01:24:57	Ullrich,Thomas S:	What drives the 5mm thickness of the glass backplate?
01:25:04	Ullrich,Thomas S:	Can that be reduced?
01:25:50	cole hamel:	It is driven by mechanical strain from atmospheric pressure. We have an alternative ceramic backplate that is 2 mm thick.
01:26:04	Silvia Dalla Torre (INFN-Trieste):	yes, there are title with 2 mm ceramic board as substrate of  the resistive anode
01:33:46	Ullrich,Thomas S:	That seems the way to go?!
01:34:39	Silvia Dalla Torre (INFN-Trieste):	yes, of course: the difficulty is to get an LAPPD like that from INCOM; I do not know how few they are
01:34:50	cole hamel:	Ceramic is technically more challenging to seal, but we are switching over from glass to ceramic going forward.
01:39:43	Mike Foley:	an all ceramic lower tile assembly can be fabricated routinely.  Sealing a fused silica widow to a ceramic sidewall has also become routine.  Supply chain availability of components has been slow and as Cole has mentioned , Incon is transitioning to an all ceramic package.  The smaller 10 cm HRPPD is made only in ceramic
01:57:57	Alexander Kiselev:	the 10um pore tile which eRD110 (via BNL) ordered from Incom recently, will be a short stack all ceramic body, just to mention this
02:21:31	Alexander Kiselev:	one can also use the L01i board with 8x8 6mm pixel fields, which is also passive (we used it first week at Fermilab last time, together with tile 126)
02:22:35	Ullrich,Thomas S:	Even risking to accumulate some delays in the meeting it might be beneficial  to give some more time for Q&A.
02:39:36	Alexander Kiselev:	peak stays at the same place for the first few curves
02:39:47	Alexander Kiselev:	these are single photons
02:39:55	Alexander Kiselev:	indeed
02:52:15	simona:	single photo*electrons*  :-) JINST 16 (2021) 08, P08005 and for maPMTs exclusively JINST 8 (2013) P09004
03:22:04	Zein-Eddine Meziani (he/him/his):	First tests of stripline LAPPD # 41 in Hall C at JLab with a scattered electron beam off a hydrogen target in an open environment together with tests of MaPMTs.  %\cite{Peng:2020iyl}
