Quick summary - to be updated

CRYSTAL TESTING 2015/16

  • Discussion about available facilities
  • IPN-Orsay: Transmittance (L&T, Varian Cary 4000), irradiation with source, Light Yield with cosmics
  • Giessen Univ: Transmittance (L&T, Varian Cary 5000), Irradiation with source (Co-60, uniform), Light Yield with source (T=18 degrees +- 0.1 deg)
  • CUA/CU: Transmittance (L&T, Perkin-Elmer Lambda 750), irradiation option with Xrays, Light Yield with Na-22 source (temperature stabilization better than 1 degree)
  • Caltech: Transmittance (L&T, Perkin-Elmer Lambda 950), irradiation with source (Co-60, Cs-137 - pointlike?), Light Yield with source
  • JLab: Transmittance (L&T, integrating sphere), prototype testing, fADC-based readout
  • Discussion about crystal selection and testing sequence at different institutions
  • Select a sample from 10+5 (2014) and from 30 (2015) crystals, then test at one institution, and send sample to the next institution
  • Discussion about using PbWO4 crystals at an EIC
  • Action item: GEMC of crystal matrix in EIC detector environment


MAGNET UPDATE

  • Discussion of two options for NPS magnet steel
