Overview

Detector History

The detector was constructed during the summer of 2004 by 6 high school students from the Pittsford Mendon, Canandaigua Academy, and Harley under the supervision of a physics teacher from each high school. The group was directed by Professor Kevin McFarland. The project was part of PARTICLE, a program to encourage more in depth study of the standard model in high school class rooms.

Detector Components


The detector is composed of two stacked scintillating panels, each approximately 0.75m x 3m and 200lb
Each panel has a Photo-Multiplier Tube on each end. The two PMT's are wired into a junction box for each panel.
The two junction boxes are wired into a QuarkNet DAQ board, which is interfaced to a computer running Linux.
In addition, small scintillator paddles of known efficiency have been placed above and below the detector to monitor the efficiency of each large panel.

A more in depth description of the DAQ board and software is available in the Technical section.
