RUN 375: 12C pilot run |
|
|
12C beam + empty target after measurement of 9C momentum distribution.
trigger t1-8 + cats 1 2 %30000 + plastic %10000
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. |
