The Prototype

This prototype was designed and build by Marco and Mike (graduated 2012) to model a small section of the SHMS Kaon Aerogel Detector, and to study the characteristics and behavior of both the aerogel panels and the 5" diameter PMTs. It is composed of a single metal light box in which the aerogel panel is held by a wire grid (note that the aerogel is not flush with the sides of the light box). The 5" PMT window is positioned in the bottom half of the light box, and the lid of the light box is removable to allow for changing the number of aerogel tiles stacked within.

The Experimental Setup

The experimental setup will be composed of a triple coincidence with the initial gate being provided by two 2" diameter PMTs with plastic scintillator paddles.

2" PMT Double Coincidence Runs

The 2" PMTs are currently being tested in double coincidence for optimization. Runs have been performed over a range of high voltages (1600-2200V). There is approximately 55cm^2 of overlapping scintillator paddle area, and the scintillators are approximately 1 cm apart.

Upcoming projects include creating a more stable setup for both the double coincidence tests and the triple coincidence setup for the prototype experiment.
