Fri May 31 19:12:01 2024, CB, EM, Run 13 - test with beam
|
20:00
The beam is set at the correct energy, operators cross-checked it again. What we see at 750 is due to the molecular beam. The operotors
are trying to optimize and get rid of this in the next 30min. |

Thu Dec 8 14:41:19 2022, PJCS, Results of tests on AIDA PSU in DL T9 8x
|
We opened one up and soldered a co-ax cable to one of the +6v power contacts at the output of the filter board.
Connecting this to a 'scope we observed a level of +/- 5mv noise with no FEE connected.
Connecting one FEE made little difference. |
