Restoring PS test setup [1]

• • Fabricating prototype consisting of 5x5 PWO4 and 5x5 LG modules

  • LG modules will be instrumented with the resistive dividers (borrowed from Hall D)
    • - all dividers were testes
    • - modified PMT coupling to the LG block, use G10 tensioning plate to push the PMT towards the module
    • - testing LG PMTs (FEU-84)
  • The prototype will be places inside the CCAL box
    • modified the cooling plate to accommodate all modules
