intro: this doc will walk you through starting up the RGA, gathering data, and sending it off for qualification
highest pressure for RGA use: 7.6E-6 torr
[or, if you want to use faraday mode (but why would you want to do that?), max pressure = 5 x 10-4 Torr]
connection issues? see Computer Recognition of RGA
Gathering data:
double check:
- pressure is below 7e-10 torr
- valve to RGA is open
heck, double check all valves!
software settings:
filament on
accuracy 6
electron multiplier
(w/ the lowest option in the drop-down menu)
saving data
to prevent the computer falling asleep: open an image (any image) and put it on slideshow
*insert video of RGA startup*
Email data to Peter Stefan (CC Brady Robertson and Cynthia Melendrez) for official qualification judgement:
- The pressure that the cold cathode gauge reads as data collection stops.
- The data file. Found here:
- Cart number
