JB Undergraduate Research Progress, Fall 2013

This page gives an overview of the work I have done under the supervision of Dr. Richard Jones during the Fall 2013 semester.

Finalizing summer work

I worked in the lab as a student worker during the summer of 2013. I spent my time working on a proposal for a chilled water line for the servers in P403. I finalized this document in the beginning of the Fall 2013 semester. It can be found here.

Familiarizing myself with the active collimator

When I first gained access to the active collimator, I took it apart in order to understand its structure. Below are pictures that I took upon its disassembly.

I read Igor Senderovich's PhD thesis very carefully in order to understand the active collimator's purpose and how it works. This project is largely based on Senderovich's work from his time under Dr. Jones's supervision. The active collimator has been quality assured by Alex Barnes, James McIntyre, and Dr. Jones. A detailed PowerPoint regarding the use of the active collimator in the GlueX experiment was written by Dr. Jones, Igor Senderovich, and Ann Marie Carroll for an APS/DNP meeting in October of 2012.

Data Acquisition

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 Tektronix TDS 2024 Digital Storage Oscilloscope. I connected each of the tungsten pin cushions within the active collimator to a cable with an RF coaxial adapter input which was connected to the face plate and a BNC output which was connected to a PMT-5R amplifier.
