- Note down pressure of all gas bottles
- give that list to the beamline staff (it is an information, wether a bottle can be reused the next time)
- CLOSE all gas bottles
- inert gases like Helium might stay opened, let the valves and the bottle regulators stay opened
- Release Pressure: connect the equipment with tubes to the exhaust and let the exhaust suck the gases
- the bottle has to be closed, the pressure regulator and all ball valves should be opened
- PURGE all your equipment, as well as the gas-tubes and MFC system with helium
- Connect the single tubes at the wall to the exhaust
- Connect the Gas-Outputs at the wall (singlewise) to the exhaust
- close the bottle-pressure-regulator
- disconnect the tube at the pressure regulator and connect it to an inert line
- PURGE the lines with helium
- Disconnect all tubes in the Experimental hutch (EH)
- Tidy up
