 My research thus far has been focused on examining the electronic properties of the active collimator. I spent a few weeks working on capturing waveforms with a [[Media:jbtdsmanual.pdf|Tektronix TDS 2024 Digital Storage Oscilloscope]] by tapping the pin cushions with a piece of metal that I was holding in order to build up a charge on the cushion. I connected each of the tungsten pin cushions within the active collimator to cables with an RF coaxial adapter input which was connected to the face plate and a BNC output which was connected to a [[Media:JbAmplifier.pdf|PMT-5R amplifier]]. I used a [[Media:JbPowersupply.pdf|F-100PS 15 Volt DC Power Supply]] to power the amplifiers. However, I did not have control over the amplifier's gain setting with this setup.
-Igor developed a data acquisition LabView program for the active collimator. The program allows the user to vary the gain setting on the amplifiers from 10^6 to 10^12, record the potential difference across each of the tungsten pin cushions at a frequency of about 80 data points per second, and calculate Fourier transforms on the received signals. The program is run on a PC that Alex Barnes and I built which contains a  data acquisition card. Below are pictures of the pieces of equipment used for data acquisition.
