FLIR project updates- Initial tests

• 10:00: Starting test in position 2 cm to the black wall.
• Parameters : 0,305 A, 05,5 V and the temperature inside the mirrors 141,8°C.
• 10:23 Finished this first tried and take snap. The image is attached below.
• The name for the picture for this tried is “AcquisitionImage(Apr-19-2023_10 23)”.

• 10:37. Starting test in another position now 3 cm distance to the black wall ( this is more close than the original position.)
• Parameters : 0,348 A, 05,5 V and the temperature inside the mirrors 160,3°C.
• 10:57 Finished this second tried and take a snap. The image is attached below.
• The name for the picture for this tried is “AcquisitionImage(Apr-19-2023_10 57)”.

• 11:03 Starting test another position 1.3 cm distance to black wall.
• Parameters : 0,347 A, 05,5 V and the temperature inside the mirrors 158,7°C.
• 11:18 Finished this second tried and take a snap. The image is attached below.
• The name for the picture for this tried is “AcquisitionImage(Apr-19-2023_11 18)”.

The next step should be fix the problem with the shape (aluminum foil lid).

• 01:50 pm: Starting test position 34 mm distance to black wall.
• Parameters : 0.100 A, 1.5 V and the temperature inside the mirrors 40°C.
• 2:09 pm : Finished the test and figured out this position it is too far the black wall so now we change for more close position.

• 2:17 pm: Starting test in another position: 10 mm distance to the black wall( this measurement is between the black wall and the aluminum lid)
• 2:26 pm : Finished this second tried and take a snap. The image is attached below.
• The name for the picture for this tried is “AcquisitionImage(Apr-21-2023_14 26)”.

Note: The second tried the temperature didn't up more than 40°C for 8 minutes so I change the current for a few seconds. I started with 0.98 A with 1.7 V and up until 0.350 A with 2.5 V, just for a few seconds and in this way the temperature up to 72°C and I get the snap.
The next step should be understand the problem with the shape and work in changes for get the triangle in the FLIR image.

• Today i wiped, bagged and tagged two cables for the vacuum system. I used IPA wipes for cleaning this two split power cord. I attached a image below.

• The new mask for the reflector.
• 1:40 pm: Started reconfiguration on the FLIR camera project. Changed the old bridge for the new mask-bridge.
• 2:00 pm: Started figure out the best way to cutting the aluminum foil with the new mask. Unfortunately, I had been some problems for cutting the perfect shape triangles with the mask because the size inside the triangle is different (smaller) than cutter/knife, so is not able to do the cut with precious and carefully then maybe I need other tool for this job. Also I tried use the scissor, didn't work. However, just for the initial testing I worked with the not perfect triangles shape.
• 2:49 pm: Started installing/attaching the light in the mask.
• 3:21 pm: Finished installing the light in the mask-bridge.
• 3:22 pm: Started testing the current and voltage in the new mask-bridge for make sure the light cable is working well.
• 3:25 pm: Started measurement the resistance with multimeter.
• 3:29 pm: The measurement looks fine. The multimeter show us 14.1 Ω;
• 3:38 pm: Started putting the reflector( with the mask attached) in front of the black wall.
• 3:44 pm: Started roll the testing with the python code to observer the behavior with this new mask. Parameters: 0.14 A and 1.9 V.
• 4:00 pm: Started snapping. Parameters: 0.13 A and 1.9 V. Final Temperature: 42.7 C.
• 4:02 pm: Started trying again with more current. Parameters: 0.16 A and 2.2 V.
• 4:36 pm: Started snapping. Parameters: 0.16 A and 2.2 V. Final Temperature: 50.3 C.
• 4:55 pm: For now, we can't see the triangles in the snap so i need do some changes.

• To do:
  1. Change the FLIR camera position for the other side on the table.
  2. Start the test without the black wall.
  3. Try a better tool to cut the triangles inside the 3D-mask.

Reinstalling the mask and Reconfiguration FLIR position.
• Today i change the aluminum foil inside the 3D mask. After some tries i was able to have a better shape for the triangles.
• I reinstalled the connections (the light with the thermometer point). Also i checked for the focal point inside the reflector, looks fine.
• I did a reconfiguration for the initial tests, without the black wall. I moved the FLIR camera and the Reflector-Mask for other position on the table.
To do:
• Start the test with the power current on.
• I need figure out a better position for the light cables because in front of the mask isn't a good position for us do measurement.

Initial tests
• 10:30 am : Started trying take some test with the new position/configuration between the 3D reflector-mask and the FLIR camera.
• 10:41 am : Started running the python code and take a snap. Parameters: 0.10 A, 1.4 V.
• 10:50 am : Started take the snap.It is possible see the triangles, this is a good thing. Negative thing: The middle/center point for the light maybe would be some problems for the future measurements. Parameters: 0.10A, 1.4 V and 41 C.
• 11:00 am : Started working to better align the entire structure. And double-check the distance between the 3D reflector-mask and the FLIR camera, following the instructions in Cassidy's Final FLIR Project Report.
• 11:10 am : Difficult point: I tried to attach the complete FLIR camera to the table, but I had a problem to secure the four screws to the table, the distance is not completely compatible with the table stand. Yesterday I just put two screws in the diagonal position, it works fine, but it's not the correct position to work.
• 12:00 am : Note: Two triangles take more long time to come back a not (low) irradiation position (east and south point).
• 2:00 pm : Started running the python code again.
• Parameters: 0.13 A 1.8 V.
• 2:30 pm: Started take snap. Parameters: 0.13 A, 1.8 V and 49.1 C
• 3:00 pm: Note: This time every triangles was able to come back a low irradiation position.

Change the 3D mask
• Started removing the old mask in the reflector.
• Started cutting the new aluminum lid for the new 3D mask and assembling in the 3D mask.
• Started doing the new cable connections for the light.
• Started testing the resistance in the new cable connections. The multimeter show us 14.2 Ω.
• Started attaching the mask with the light and the thermometer sensor.
• Started assembling the 3D mask in the reflector.
• Started the initial tests.
• 2:00 pm: Started testing the new mask. Parameters: 1.4 V 0.1A and 27 C
• 2:38 pm: Started taking snap. Final parameters:1.4 V 0.1A and Temperature: 39.9 C
• Started doing some adjustments in the triangles shapes for the futures tests.

• We changed the FLIR Focus Distance for around 0.55 m.
• Note: The old focus distance was 1.3 m.

• We tested this new focus distances and looks good. I attached a snap below.
Parameters: 0.1 A , 1.5 V and 38.4 C.

Test without the black wall.
General test:.
• 11:15 am : Started running the code. Parameters: 0.11 A, 1.9V and focus distance around 0.55m.
• 11:28 am : Started snapping the screen. Parameters: 0.12 A, 1.8V and 44.1 C .
First trying:
• 01:18 pm : Started testing and collection data. Parameters: 0.09 A, 1.4V. Reference position: (0,0).
• 01:28 pm : Started snapping the screen. Parameters: 0.10 A, 1.5V and 37.9 C. Reference position: (0,0).
Second trying:
• 01:34 pm : Started testing and collection data. Parameters: 0.08 A, 1.4V. Reference position: (0,-0.10).
• 01:44 pm : Started snapping the screen. Parameters: 0.09 A, 1.7V and 35.8 C. Reference position: (0,-0.10).
Third trying:
• 01:50 pm : Started testing and collection data. Parameters: 0.08 A, 1.3V. Reference position: (0,-0.05).
• 02:00 pm : Started snapping the screen. Parameters: 0.09 A, 1.4V and 35.4 C. Reference position: (0,-0.05).
Fourth trying:
• 02:04 pm : Started testing and collection data. Parameters: 0.09 A, 1.3V. Reference position: (0,0.05).
• 02:14 pm : Started snapping the screen. Parameters: 0.11 A, 1.6V and 41.7 C. Reference position: (0,0.05).

Note: So today i tried collecting data for every possible position in Y (height) way for starting analyses and compares the triangles shapes. I realize maybe we get a problem because i keep the same time in every try but the final temperature and the parameters change every time, so i will try do a better system to keep the parameters equal, maybe i can wait the reflector be back to a normal temperature after every test or keep the system on all the time and just change the reflector position. I pretty sure this was the problem.

Test without the black wall.

Note: So today i collected data for some positions in axis Y (height) for starting analyses and compares the triangles shapes. I tried keep the same parameters every time.

First position:
• 01:20 pm : Started testing and collection data. Parameters: 0.10 A, 1.6V. Reference position: (0,0.05).
• 01:30 pm : Started snapping the screen. Parameters: 0.10 A, 1.6V and 37.7 C. Reference position: (0,0.05).
Second position:
• 01:34 pm : Started testing and collection data. Parameters: 0.10 A, 1.6V Reference position: (0,0).
• 01:44 pm : Started snapping the screen. Parameters: 0.10 A, 1.6V and 40.6 C. Reference position: (0,0).
Third position:
• 01:50 pm : Started testing and collection data. Parameters: 0.10 A, 1.6V. Reference position: (0,-0.05).
• 02:00 pm : Started snapping the screen. Parameters: 0.10 A, 1.6V and 39.1C. Reference position: (0,-0.05).
Fourth position:
• 02:03 pm : Started testing and collection data. Parameters: 0.10 A, 1.6V. Reference position: (0,-0.10).
• 02:13 pm : Started snapping the screen. Parameters: 0.10 A, 1.6V and 39.6 C. Reference position: (0,-0.10).

• Today we change the distance between the FLIR camera and reflector (3D-Mask with mirrors and light). Now the distance is 0.2032 m.
• Note: This distance is just for take a snap most close possible but we need move again for a little far way because in this distance we can't move up and down the reflector for have data to compare.

• Used the closest point possible for the reflector in front of the FLIR camera.
• 11:32 am : Turned on the electronic device (current on) for started taking data.
• 11:50 am: Started checking the temperature and the parameters.
• 12:04 pm: Started taking snap after waited for 30 minutes with the current on. Parameters: Current: 0.13A , Volt: 1.8V and Temperature: 51.4 C.
• Note: This snap is in the most close point possible, after that I should be change the reflector position and also the optical focus distance in the FLIR camera.
We can see, in the photo attached below, thought in this closest position the cable connect to reflector is a bit problem to take a good snap also the have issues to keep very uniform triangles (temperature) in the reflector.
• To do: I'll change the position on the light inside to see if the problem it is in the focal point inside the reflector (mirror).

Cleaning the heater system parts.
• 04:32 pm: Started wiping the heater system parts.
• 06:38 pm: Finished wiping the heater and some parts to the system. I wiped, tagged and bagged the heater system, power cables, adapter cables and power connectors. Also I wiped, bagged and tagged the aluminum foil tape.
• 06:43 pm: I putted all bags inside the cleanroom.
• To do: I started but I was not able to finished wiping the heating and cords for the heater system so I will finished this parts after.
• I attached the photos below.

• Cleaning the heater system parts.
• 09:13 am: Started wiping the last parts for the heater system (heating and cords).
• 10:18 am: Finished wiping the parts to the heater system (heating and cords). I wiped, tagged and bagged the heating and cords.
• Note: In some parts looks like the silicone insulation material is having some sort of residue on the wipe so I wiped very careful this part and just for a few minutes.
• 10:23 am: I putted all bags inside the cleanroom.

I attached the photos below.

Heating system installation

• Today we started installing the equipments for the heating system.
• First: Started installing the heating cable on the top lid and covered it with aluminum tape.
• Second: Started installing the insulation cover on top of the chamber lid.
• Third:Started installing the heating cable from under the vacuum chamber and covered with aluminum tape.
• Forth: Started installing the insulation cover under the vacuum chamber
• Note: The under part of the chamber vacuum was very difficult to cover, so we spent a little time on it and we couldn't finish the whole installation today. So tomorrow we should be able to keep doing the installation.

Dr. Richardson installed the new cabinet outside the room for the PPI equipments, and then I wiped all surfaces inside and outside of the new cabinet.

Dr.Richardson and I have finished organizing the PPI within the new cabinet. Also we have new supplies of gloves, and will likely have more supplies for other PPIs soon.

Heating system installation - Second day.

• Today we kept installing the equipment for the heating system.
• First: Started installing the two heating cable around the chamber vacuum, the arms and covered it with aluminum tape.
• Second: Started installing the insulation stuff around the vacuum chamber and around the connections points (the arms) in the vacuum chamber.
• Third:Started installing the heater system (electronic device) and tried testing.
• Note: The around part of the chamber vacuum was difficult to cover, so we spent a little time on. Also one heater system electronic device wasn't working because one fuse is burned so we could not finished this part and we need wait for a new one to replace and working on it.

Today I change the distance between the FLIR camera and reflector (3D-Mask with mirrors and light). Now the distance is 0.3282 m.

• Note: In this distance is possible move up and down the reflector and take data to compare.
• The focal point inside the reflector keeping like little problem, every time I tried adjust this I got some triangles is not with "perfect emission" (looks like different than the others). Also if I move up or down the focal point inside the reflector have some issues as well.Therefore I am working on that.

• 08:59 am: Turned on the electronic device (current on) for started taking data.
• 09:37 am: Tried understanding the error in the focal point. I realized the pillars was in the wrong place and because of that we got problems to keep the reflector in the correct position to FLIR focus.
• 09:58 am: Started checking the temperature and the parameters.Changed the pillars to the original position (0.5645m) just for checking with the problem was the pillar in the wrong place.
• 10:06 am: Changed the reflector to point (0.3282m) and now in the correct position for the pillars. Started take snap and collecting data. I moved up and down the reflector for got data to compare later.
• 10:37 am: Used the closest point possible for the reflector in front of the FLIR camera with the correct spot for the pillars.(0.2032m)
• 11:00 am: Started taking snap after kept the current on for a few hours. Parameters: Current: 0.10A , Volt: 1.3V and Temperature: 41.9 C.
• I attached below the snap in the most close point possible, now i can see a better photo and I think a fixed the problem about the focal point in the reflector for have more uniformity between the triangles, isn't perfect yet but now is just some adjustments. Furthermore after that I should be change the reflector position and also the optical focus distance in the FLIR camera and try use the black wall.
