ORTEC MODEL A-576 A-PAD Preamplifier, Amplifier, Discriminator with Bias Supply 1. DESCRIPTION The ORTEC Model A-576 A-PAD is a single- wide The energy ranges controllable from the front panel NIM module intended for performing alpha are 3 to 8 MeV, 4 to 7 MeV, 3 to 5 MeV, 4 to 6 MeV, 5 spectroscopy and counting when used in conjunction to 7 MeV, and 6 to 8 MeV. -
