HOW TO USE:
Click on the names in the key to hide/show a dataset. Use the highlighter bar to select the time window you would like to view (or use the zoom buttons on the top left if enough data is available. I will likely not store data for longer than a couple days.). Just ignore the "Load Historical ... " button. The drop-down menu is used to select various channels but I only have a single channel so far. The "5 Loads" concerns the "Load Historical" so ignore it just as much. You can grab a picture of the graph or even download a csv of the data itself by clicking on the top right drop-down menu.
NOTES:
- The pressure axis is logarithmic while the temperature axis is linear.
- When the pressure suddenly flys up to 0.00989 torr, the gauge has been turned off. There are typically two reasons to turn off the gauge: (1) the chamber is at a high pressure ( >1E-5 torr) and so the filament is turned off for its protection or (2) sensitive optical experiments are being run. The ion gauge filament emits a fairly bright yellow glow that floods our ccd, making such experiments impossible.
- Experiments are usually run at room temperature (295 K) but are also conducted at either 80 K or 5 K with liquid N2 or He, respectively, using a flow cryostat.
- Breaks in the data are due to the crashing/breaking of the python script. I'm still working out all the kinks.
