• cabling and installation of the big PCBs
• preparation for detector checkout
• detector checkout

• Assembly time estimate

• Crystal stacking - COMPLETE (10 June 2022)

• onsite personnel: IJCLab-Orsay (6), AANL (2), CUA (2-3), OU (1-2); onsite contacts: Carlos, Vladimir, Brad
• All crystals are stacked and 4 full columns of PMTs and electronics are cabled - assembled NPS picture

• Preparation for detector checkout - planned for July/August

• onsite personnel: AANL (2), CUA (1-2), OU (2-3); onsite contacts: Brad, Julie/Paul, Carlos
• In order to perform the detector tests, there is work to be done outside the calorimeter box:

• HV cables, signal cables and LV cables need to be put in place and hooked to the DAQ, which needs to be setup.
• Power supplies (HV, LV) need to be setup.
• Same for slow controls (for HV and LED), etc.
