L980519423:01:14I'm having trouble with the Rayleigh system will take 0EG
a look at it when it get more dark
L980519423:20:31I switched to the 10% PMT. And I got some counts. I think77370EG
that when the High voltage unit failed the 90% PMT must
have gone with it at the same time. I will swap those tubes
later on in the run to see if the 10% PMT will give me
some counts in the 90% position. Turning off coolers
