Abstract

The figure-of-merit for a gelled NE213 scintillator cell from Bubble Technology Industries is determined for a variety of digitizing speeds and vertical resolutions using the digital-charge-integration-comparison method for pulse shape discrimination. If a digitizing board allows for an increase in the vertical resolution at the expense of the digitization rate, then there is an optimal combination of the two. For the Gage Board 82G, a board that does allow this tradeoff to be made, the best pulse shape discrimination occurred for digitization rates and vertical resolutions of 1 GS/s and 8 bits, 500 MS/s and 9 bits, and 250 MS/s with 9 bits.
