Equipment Setup
We got our pulse height to be 3 V. 2.4 was not super attainable. Oh well. PZ was adjusted
Once at 20microsecond timescale we noticed some undershoot going on. Pole zero adjustment was modified to compensate for this.
We got a spectrum that we recorded for 1 minute. It looks like 5.9 after changing vertical scale to "A" for auto.
We had to adjust 11to 595.6V on the high voltage power supply to get our spectrum in the right place.
We set the lower level discretization to 130. 75 still incorporated background noise.
Accurate coefficients are in the cobalt ASCII file.
First rip on the unknown sample, 616 counts at 658kev
Exercise 5.7 Best guess rubidium at 657.777 134 cA gross area 2507 With Cs source now, gross area 6886 background count gross area 81
