Ultra low-temperature cascade refrigeration system repair @AppliedScience

I bought a -100*C refrigerated cold trap from a surplus sale, which was not operational. In this video, I describe how the unit works after recharging its second stage with R1150 (ethylene) refrigerant.

$Use an oscilloscope to collect optical spectral data Im using my new Tek oscilloscope to collect data from a DIY spectrometer. The scope is in X-Y mode with infinite persistence. The X axis is controlled by the rotational position of the diffraction grating in the spectrometer, and the Y axis is controlled by the photomultiplier tube, which is detecting the spectra. In this video, I discuss the scope setup, and in future videos, I will talk more about the spectrometer, and how to use it.$
