Research Gallery Images collected while performing research at the College of the Holy Cross. (Click on an image for an expanded view) Cosmic ray telescope. Scintillator paddles shaped as isoceles trapezoids (outlined in red) emit light energy as energetic particles pass through. Telescope PCB image. Created using PCBExpress, this PCB image illustrates every connection between electric components on the circuit board. Red connections are on top of the board, while the green connections go underneath the board. You can download a copy of the PCB file here. Circuit board schematic page 1. Also created using PCBExpress, this schematic conceptualizes the connections between components with no regard to physical location. Page 1 focuses upon connections between the binary clock system. You can download a copy of all four schematic pages here. Circuit board schematic page 2. Major components include the Arduino Leonardo, coincidence logic gates, and clocked data flip-flops. Circuit board schematic page 3. Crystal oscillator, more logic gates, and a binary counter. Circuit board schematic page 4. Voltage regulators, analog to digital converters, and some capacitors.
