MuCap electronics cabinet

Hi Peter,

I'm currently at work on the CAENs, and I am trying to fix this damned
clock business once and for all.  After studying the signals with the
scope, I believe that the problem is most likely the NIM/ECL converter--
the ECL output signal is absolutely horrendous and distorted, so the CAENs
are not receiving the healthy 50% duty cycle signal they require.

Therefore, I would like to first attempt to swap modules, and see if that
remedies the situation.  The problem is that I cannot get into either the
electronics cabinet (on the landing above the muE4 area), or the lockbox
just inside the door of our barrack, where I know that our keys are
sometimes kept.  Do you know where any of these keys could be found?

BTW, if the CAEN problems have been due to a faulty ECL signal, then it is
likely that we could return the CAENs to a 50 MHz signal after all.  I
will, of course, check that the CAENs operate properly at that rate, but
the CAEN people seemed to think that 50 MHz would be fine.

P.S.  I almost forgot--are any of our PSI bicycles still here?  I could
really use one.
