University of Florida - DCRC Noise Analysis
In March 2012 I was awarded a research scholarship through the University of Florida titled University Scholars. I used these research funds to perform noise analysis tests on a circuit board. This board is the main communication device used to interface with dark matter detectors in the Super Cryogenic Dark Matter Search (SuperCDMS).
Abstract - This project is done in support of the Super Cryogenic Dark Matter Search experiment (SuperCDMS) and involves analyzing the effect that environmental electrical noise has on a Detector Control and Readout Card, or DCRC board. Sources of electrical noise can come from lights, pumps, air conditioning units, electronics, and many other places. The method used in this project takes a signal measurement in the lowest possible noise environment and compares that to various situations of different noise. The power spectral densities of various signals were analyzed. Once it is understood how noise affects the board, steps will be taken to eliminate removable sources whether by shielding or otherwise. Ultimately, the researchers of SuperCDMS will be aware of how the signal they receive is affected by noise.
