| − | * Reviewed minutes from last meeting
| |
| − | * Looked at Sasha's installation wiki page
| |
| − | ** Showed different possible damage to wrapping of existing lead glass modules
| |
| − | ** Is aluminum being stuck to module surface a performance issue (light yield)?
| |
| − | *** Really no way to test now
| |
| − | *** Need to decide threshold for re-wrapping
| |
| − | ** Some inspection/labelling needed prior to unstacking of blocks
| |
| − | ** Sasha proposed that him and Arshak inspect each module after removal to decide on action to be taken -
| |
| − | ** Mark and Malte need to be in loop for base and pmt changes
| |
| − | *** Possibly test light yield on first 100
| |
| − | ** Malte asked who unstacked the original modules from BNL and what were the issues
| |
| − | ** Looks like we will have about 500 good PMT spares
| |
| − | ** Sasha presented manpower requirements
| |
| − | *** would need 2 students for 30 weeks to re-wrap all old modules
| |
| − | *** Total 11 students for 3 months will be needed for project (Eugene to check budgets)
| |
| − | *** JLAB folks responsible for unstacking modules - Hall D Techs/DSG?
| |
| − | *** Sasha/Arshak would train students to do module refurb
| |
| − | *** Students would label and bundle cables
| |
| − | *** JLAB tech staff handle structure, darkroom, cable trays, racks
| |
| − | *** JLAB electronics group handle crate installation and cabling possibly with help from DSG
| |
| − | *** Students would handle moving existing cables to adjacent crates on north and south racks
| |
| − | *** Need to get a final list of universities supplying students
| |
| − | *** Maybe best to downgrade the hall from RAD worker 1 to Gert only
| |
| − | ** Sasha mentioned the need to re-strap some existing 25 micron brass strap crystal modules
| |
| − | ** Need to start developing procedures for all aspects of the project
| |
| − | ** Need to define workstations needed - add to Sasha's table and develop a layout
| |
| − | * Need to have electric power added to south side of FCAL platform
| |
| − | * Need to update strawman schedule with more detail including resources
| |
| − | * Lead glass acrylic sheet same design as original - need to remake panes for new geometry
