The width and location of the measured in-air change in temperature profile has been determined to be 0.045m and 0.137m respectively. Subsequently, a fake irradiance profile was able to be generated that best resembled what the actual irradiance profile could be using this information for testing in COMSOL. The generated irradiance profile that output the most similar change in temperature profile as the measured in-air profile has been included as well as the change in temperature profile it produced on the blackbody screen "test mass" model in COMSOL. |

Cynthia | Update | Interferometer Simulations | O4 vs O5 cavity scans with ITM plume guess or ETM |
| So far the proposed solution for what to use for O5 ITM mirror for SIS simulations is either the plume guess file or using the O5 ETM mirror for ITM. I had ran a cavity scan for both of these possibilities and it seems like the results produced are fairly different. The next step is most likely moving on to adding the Frosti effects including both of the proposed possibilities, and before this, a few confirmations and verifications are needed using similar previous studies to make sure my code produce the right result. |

Cynthia | Update | Interferometer Simulations | current status on cavity scan with effects of FROSTI |
| I used the code and arm cavity model used for previous O5 study on mirrors and HOM (the pdf of the study and the result can be found at https://dcc.ligo.org/LIGO-G2100878), but it seems like the result I obtained is different from the study result. Since my cavity scans codes have a large portion of it relying on this code, I will have to go over the study result and the code to make sure there is no issue with that code itself first. There are also some other updates or issued encountered when I tried to plot the mirror maps with effects of FROSTI. |

Cynthia | Update | Interferometer Simulations | corrections on assumption for O5 coating |
| The document recording ETM07 and ETM08 coating (T2300093) was discussed:
the current plume files are not necessarily correct in a way that LIGO lab have tried to add it on uncoated ETM such as ETM07 and it does not match what the coated ETM07 would look like.
the plume should be added on top of the uncoated ETM instead of assuming an ideal ETM. According to Garilynn, the imperfection on uncoated ETM matters.
So far the possible ETM data used for O5, ETM 11,14,19, and 20 are all uncoated, and different ways could be used to predict the plume, including the plume data on LIGO dcc or subtract the uncoated data from the coated for O4 ETM and use that as another guessed plume. |

| Today I unpacked and installed the new HEPA filter for the lab. It is an Omni CleanAir OCA1210 capable of 1200 CFM. This flow rate is sufficient to turn over the air in the room once every 4 minutes, or 14 times per hour. Hopefully this will cut down on our particulate accumulation issues. |

The first set of 2 measurements from today were under the table by the clean room entrance, the next two were under the table by the vacuum chamber, the next two were on the floor by the vacuum chamber lid, and the last two were on top of the table for comparison. All measurements were taken using 2 minute sample time. |

| Today I was able to come in and wipe down both sides of the vacuum chamber lid using the regular alcohol wipes and also wipes that were left to dry in the fume hood then saturated with acetone. I managed to get a good amount of the residue off both the inside and outside surfaces of the lid, then did a test wipe of both sides using acetone-soaked wipes; pictures of the wipes are attached below. Once I finished with the lid, I used another acetone wipe to test wipe the inside of the vacuum chamber. The inside is still giving off residue, but very minimally, a photo for this is attached as well. |

We flip the chamber and put chamber on the table again. A picture of the specific situation is attached below. The next step from here would be to finish the cleaning the floor .
The black residues on the side of the table probably is some reaction between the Vinil and the wipes so is not necessary cleaning this part deeply. |

Hand cleaned stainless steel containers and silver coated screws. Designated each container with its contents with the label maker and placed inside the clean room. Should be noted that the fasteners were very clean before the hand cleaning and showed not dirt on the wipes. Added these parts to the clean and bake data base sheet and designated the type of cleaning as "rough cleaning". Gabriella helped with this cleaning and today was her first day in the lab. |

I also was going to bag the viton O-Ring from the previous Batch, however it seems to have broken during the bake and I am leaving it inside the oven for now. |

Jon, Cao, Peter
This morning Facilities delivered and installed two new cabinets with sliding glass doors.
The smaller of the two (36" W x 13" D x 84" H) has been installed in the Clean & Bake area adjacent the flow bench. The larger one (48" x 16" D x 84" H) has been installed in the back of the room next to the electronics bench. Both cabinets have been securely anchored to the wall in two places each for earthquake safety.
We also installed the sliding glass doors and leveled them. However, we have not installed any of the shelves yet because the cabinets are quite dirty from the installation. Everything needs to be wiped down with IPA wipes, and it will be easier to do that before the shelves are in place. |

Possible is necessary order more IPA wipes for keep cleaning in nexts weeks.

Aiden | Summary | General | Clean and Bake batch 7 |
| Today gave another cleaning to the MDC gate valve. It is still very dirty an will need more cleaning. I also cleaned the other 3 valves and the argon leak. These are also in bags inside the clean room. I cleaned them by hand with IPA wipes and had to specifically give the MDC up to air valve a harder clean with acetone as it was not getting clean with the IPA. This valve still has a ring around the face as shown in the first image. Be very cautious when moving the parts in the large ESD bag, it may be heavy and the parts will move inside. |

Aiden | Summary | General | Clean and Bake batch 8 |
| Starting off Peter and I refilled the deionized water barrel.
Then Aiden Cleaned and Bake the FROSTI arms and bases in liquinox for 5 minutes. Then placed them in the oven where they will undergo the following steps;
1. Ramp to 100 degC in 15 min.
2. Dwell at 100 degC for 30 min.
3. Ramp to 120 degC in 30 min.
4. Dwell at 120 degC for 48 hours.
5. OFF
Also cleaned the 2.75 MDC Gate valve for 20 minutes (10 minutes each side) in liquinox. It looks significantly cleaner in areas I could not reach before. However some areas like the flat bottom threaded holes are still very dirty. I also made sure to dry it thoroughly and wrapped it in UHV foil until I further cleaning is decided. |

| Bagged and Tagged the reflector arms and bases and placed them inside the clean room. Total of 2 bags used. Cleaned and Baked parts in batch 9 on the spread sheet and used the following procedure;
1. Ramp to 100 degC in 15 min.
2. Dwell at 100 degC for 30 min.
3. Ramp to 200 degC in 30 min.
4. Dwell at 200 degC for 48 hours.
5. OFF
Also soaked the 2.75" CF gate valve in acetone to try and clean the open threads around the part. Then cleaned it in the ultrasonic washer with liquinox for 20 minutes (10 minutes each side). It looks better than it used to but the threads still seem to be the problem and will probably need even further cleaning. |

Shane | Update | General | Clean room recertification particle counts |
| Attached are the five zone particle measurements for the clean room now that the fan speeds have been set to MEDIUM. 2 min sample time, 3 samples per zone. The occupied clean room measurements were unusual in that they generally got larger towards minute 6 instead of settling and going to zero, and for this reason didn't stay beneath the class 5 requirement at the end of the samples. The unoccupied counts look more similar to what was expected, and generally settle under the class five requirement. |

I wiped the RGA vacuum component for around 25 minutes after that I bagged and tagged this part and put inside the cleanroom. The RGA vacuum component have a big size and because off that i used the big bag.
I wiped one power cable (2 meters), bagged and tagged that and inside the cleanroom.
For the parts in the oven, a bunch of screws, I bagged and tagged the screws and put inside the cleanroom.
I put photos below about this process. |
