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.

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.
