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
