Below is a list of action items which we would like accomplish before the PrimEx Phase II run in Spring/Summer of 2021
- Aligning FCAL in the Hall
- Moving FCAL platform by about 5 mm in X-direction to make sure that the beam goes through the middle of the FCAL hole (3x3 modules). The exact position should be confirmed by the alignment group -- Tim Whitlatch
- Perform preventative replacement of FCAL bases in 4 inner rings, which is critical for reconstruction of Compton events.
- Several bases have already been replaced in this area. The status of FCAL bases in the 3 inner FCAL rings was provided by Colin and is presented in the link below.
- Status of FCAL dividers in 3 inner rings
- Perform preventative maintenance of FCAL bases.
- Diagnose and subsequently replace (reapair) bases which draw excessive current (typically larger than 15 mA), which is an indication of the possible failure. Currently estimate about 200 - 300 such bases -- Chris Stanislav, Fernando Barbosa, Matt Shepherd
- Refurbish CCAL active bases -- Support needed from Chris Stanislav and Fernando Barbosa
- manufacture 150 new active bases according to V. Popov modifications and install them on the CCAL
- Chris has already prepared a new PCB design
