Plugging along merrily!
Every 12 hours I have to refill the instrument dewer with liquid Nitrogen. This keeps the detector (CCD) VERY cold. Nitrogen is liquid at -196 celsius, and the instrument usually stays about -120 celsius. We want the detector cold so that there is no noise added to any images we take.
I’m getting into a good groove, and even checking out my spectra. About 20 minutes of exposure will create that graph! cool.
