B150 has a bunch of old AOMs of various shapes and sizes. We set up a circuit to test them. We used the signal analyser to output a signal into a mixer, have that signal go to the AOM and reflect back to the input of the analyser. The idea being we should see dips in this signal near the AOMs resonance. We did this for ~8 AOMs that we had, and have identified ones that are clearly not in working condition. The remaining ones in the ULine cabinet should all be working, with resonances observed between 60-150MHz. We will need a beam profiler to continue with AOM testing from here (maybe one of the NIR cameras that are suppose to arrive this week).
