keyword=FPP eff. drop, seems to be gas mixture problem.
Since FPP eff. was dropping on every chamber, we (Bogdan and I ) think it is clearly a gas mixture problem. Went to the gas house to
check it out. Nothing seems to be wrong, except that one of the two CO2 gas bottle alarm (right side bottle) was beeping, indicating EMPTY. But the left CO2 bottle was OK. Should check the gas mixture control unit. Paged Jack at 11:30pm.
