Beam time at KVI:

  • Myroslav offered short term beam time at KVI for proton irradiation tests of light pulser and THMP components (done on June 28th/29th)
  • More KVI proton beam tests foreseen (Pawel: Versatile Link components, Giessen: Barrel crystals)

VPTT capsules:

  • Problems with mountability of recovery LED cut out VPTT capsules
  • Thinking of 4 crystal-plastic-spacer to replace capsules of 4 crystals each
  • In the meantime the problems turned out to be caused by bad manufactured VPTT capsules - there have been similar problems with the APD capsules which led to a new production run back then, in case of the VPTT capsules the faults are less obvious
  • Sorting out the bad capsules allows going back to the original design, even cut out for recovery LED no longer needed
