[Halld-pid] Hamamatsu tube

[Paul Eugenio]

Hi Elton,


We have 2 types Hamamatsu units which were are testing.  These are  
H10570 SEL which uses an 8 stage R9779 tube and  H10534 SEL which uses  
a 10 stage R9779 tube.   We are focusing our studies on the 10 stage  
units for use in the TOF.

H10534 SEL
[ 2" Head On PMT for TOF, R9779 w/ 10
stages, selected for gain min = 1E+06,
Bialkali photocathode, , 1.8nS rise
time, 250pS TTS, active voltage divider
for high linearity, magnetic, per
attached drawing;
