- Update on liquid sample on Readout Assembly used for testing (001)
- See Sep 24, 2013 Calorimetry for background information.
- File:Readout001 Analytics.pdf Report indicates propylene glycol is the main component in the liquid, which is the additive in the anti-freeze coolant we were using. The liquid was found on the #1 modules used for testing of modules after gluing light guides.

Minutes
Attendees: Elton, David, Alam, Beni, John, Dan, Yi (JLab); Shawn (NW); Matt (IU); Zisis, Shaun? (UofR had trouble with Seevogh connections, participated by audio)
- Announcements
- Action Items
- Monitoring
- Documentation for the controls for Fcal on DocdB.
- Switches are being currently installed .
- Electrical work is ongoing with clean power expected within a week
- As soon as connected, will check interaction of control circuits with PLC
- FCAL
- Plexiglass monitoring panels arrived
- Two of the four panels were not machined correctly. Replacement panels were shipped from Eljen and arrived last Friday.
- John and Dan checked dimensions and sanded circular area to match the Athens test piece
- They have been transported down to the hall. The non-conforming panels will be shipped back to Eljen.
- The LED boards will be secured to the panels once the panels are in place. They will be equally spaced except to avoid the support brackets.
- The plan is to attach the boards to the panels using UV curing glue.
- FCAL Calibration
- Nice summary of the expected calibration procedure by Matt
- Shawn had several questions and comments
- Shawn: Should we use the gain as an indicator of dead channels? Elton: Should have an additional quality factor for each channel
- Shawn: How is the type (color) of LED recorded in the data? We need to make sure this gets into the data stream.
