- Particles account
- 10:37 am: Starting the particles account
- Zone 3:
- 0.3u: 1662
- 0.5u: 872
- 1.0u: 415
- Zone 4:
- 0.3u: 831
- 0.5u: 124
- 1.0u: 0
- 11:14 am: Start removal of calibrated leak to install 45 deg elbow
- 11:21 am: Elbow installed, re-install calibrated leak back on
- 11:29 am: Finished re-install calibrated leak, start installing gate valve on pump line
- 11:47 am: Finished installing gate valve, start installing reducing cross onto gate valve
- 12:02 pm: Finished installing reducing cross, start installing 90 deg elbow to reducing cross
- 12:17 pm: Finished installing reducing cross, lunch break
- 01:24 pm: Come back to the lunch break.
- 01:26 pm: Start installing vacuum hose to elbow.
- 01:40 pm: Finished installing vacuum hose.
- 01:43 pm: Start installing turbo pump.
- 02:00 pm: finished installing turbo pump .
- 02:10 pm: Start installing standard wall hose from turbo pump to scroll pump
- 02:21 pm: finished installing hose onto scroll pump, start installing lid. Remove lid from chamber, insert viton O-ring. Place lid back
- 02:30 pm: Secure lids with screw. Start installing turbo pump controller cable: Pass cable from outside (controller) up the top of clean tent and connect to 8 pin connector on turbo pump
- 03:00 pm: Installing air cooling unit for turbo pump, found 8 M3 screws for air cooling unit in the C&B cabinet to install the fan bracket onto the back of turbo pump. Fan control cable is routed up to the top of the cleanroom to the controller
- 03:15 pm: Installing full-range gauge cable to the controller outside cleanroom. Ethernet cables 1 and 2 are used. Cable 1 is used on the RGA line gauge. Cable 2 is connected to the main body gauge. Cable1 and 2 are connected controller's channel 1 and 2 respectively.
- 04:00 pm: Finish installing gauges cables. Cables are routed up along the frame to the controller sitting outside the cleanroom
- 04:15 pm: Finished. End-of-date particle count
