[RASMB] max out photomultiplier

[Hermes Reyes Caballero]

Dear RASMB members,

 

I was cleaning the slit ensemble in the XL-A and I though of cleaning the
PMT too. So I did it with ethanol and expose the PMT to the light when the
machine was turn on. I read somewhere in this forum that can cause the PMT
to max out, and in fact the intensity was around 6-fold lower than before
the cleaning procedure. I turn off the machine for 12 hrs and the intensity
is still very low, with no apparent recovery. Does anybody know if this PMT
will comeback? 

 

Have a nice day!!

 

Hermes
