Preparation for 2021 Run

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 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 preventive 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.
