IK | Problems | | General | Run 49 |
Counting rates continued to increase (det4 > 3kHz). Beam current looked fine on the beam dump, but beam is fluctuating, and can reach 2nA on the collimator. Asked for improved focusing.
Attached screenshots and Ge spectra from before changing anything.

Collimator ~1.5-2nA when the generator retunes itself (prob the beam gets defocused at those moments)

GJ | Problem Fixed | | Hardware | TS zeroing - cables to S-IN from VME controller - between runs 49 and 50 |
Since we were observing jumps of 16 ns in timings of all channels of whole boards, the assumption was that the
signals from logical FIFO arrive at different times to S-IN inputs to zero the TS counters.
6 originally placed cables of quite the same length were replaced with 6 cables of declared 3-ns length, same
producer, borrowed from NW's equipment. |
