Venting

Case 1: Auger connected to Echo turbo/RM through bellows

(Assuming Auger is pumped down, not questionably vented to air through leaks, etc)

Make sure trolley is not in Echo LC
Turn up Echo N2
Close Auger ion pump gate valve. Do not turn off ion pump.
Turn off Auger ion gauge
Turn off Echo LC ion gauge
Turn off Echo turbo
After turbo spins down and the Pirani gauge pressures for the Echo LC and RM are approximately equal (around 30 Torr) open all metal valve between Echo LC and RM (scroll should still be on)
Open viton seal between Auger bellows and RM
Slowly open AMV between Auger and RM
Turn off scroll
Open viton seal on RM to N2 line
Slowly leak in N2 via green 1/4 turn valve until Auger reaches atmosphere

(To be updated)

Close green 1/4 turn valve
Close viton seal valve
Turn down N2
Turn on scroll pump
When scroll bottoms out, turn on turbo
When turbo reaches min pressure, close Auger AMV
Very slowly open Auger ion pump GV (if pressure/current spikes, back off opening GV. If ion pump overheats it will shut off)
Turn on Auger ion gauge
Turn off LC turbo (goal: leave Echo RM at normal rough vacuum, not at turbo pumped pressure)
When turbo spins down, close viton seal between Auger bellows and RM
Close AMV between Echo LC and RM
Turn on Echo LC turbo
Turn on Echo LC ion gauge
Run standard LC bake on Echo
