keyword=OTR Runs
Runs 504,505 have OTR in. The operators are searching for the gamma beam on
the CsI crystal.. They are unable to see it.
Run 506 has unknown beam conditions or OTR position
Run 508 has C1 voltage =OTR 800v and c2 =1100 to stop saturation. Added 40 db of attentuator to GCALOLD . OTR is in. Do not see much in GCAL or ag1Si. Can see signal on PLIC so bckgnd is high because of OTR.
Note ag1 and CsISLAC have tripped. Dont know how to reset.
