We found the target temperature suddenly increased at around 3:40 13th.
The online beam image is still indicating the target is filled up to now. |

|
Here is the run summary of the setting 9C beam + liquid H2 target.
Up to now, we have obtained 78 hours data, including missing strips in CATS , MUST2*BEAM trigger test, and half-filled target.
We will go to 9C + empty setting from 9:10.
See spreadsheet for the detail.

start 20h47 / stop 21h08
During this run, wien filter was tuned to center the beam vertically. Final setting is 2.5 kV for negative and 2.5 kV for positive.
The run started with a primary beam intensity of 350 enA. We found that CAVIAR is counting too much and leakage current of CATS1 (0.18 micro A) and 2 (0.14 micro A) are higher than in the 9C measurement. We reduced the beam intensity to 220 enA. The leakage current of CATS1 and 2 are 0.10 and 0.08 micro A, respectively. The plastic rate is about 80 kpps. |
