at the end of the procedure i got alarms from "Overpressure FPP" and a valve in the gas line of the methane system was clicking. Jack Segal is informed - but the problem disapeared by itself.
i unplugged the gas mix controler (right rack, bottom, gas shed) from AC power.
both nitrogen bottles are full one argon bottle is empty - needs to be replaced tomorrow one CO2 bottle is empty - needs to be replaced tomorrow both methane bottles are complete full, the third methane bottle (not connected) is probably still half full and can be reconnected when one of the other two runs out.
