|
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.

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. |

12C + liquid H. Before the run, the beam stopped for 2 hours due to the gate valve of E9 shut out the beam. This is because the manually operate turbo pump was turned off by itself due to unknown reason. Sébastien came to close the valve of this turbo pump and evacuate E9 using another turbo pump only. The vacuum of E9 is about 4e-5 mbar as of 9 am.The interlock is set at 9e-5 mbar.
