Alpha Duo Compact, all-in-one, bench-top, dual channel alpha spectrometer	Alpha Mega Compact, all-in-one, bench-top, large chamber, single channel alpha spectrometer
Alpha Ensemble Modular, all-in-one, bench-top or rack-mount, Multi-chamber alpha spectrometer

Alpha Duo
       Benchtop dual alpha spectrometer with two alpha spectroscopy channels. Each unit includes 100% fully computer controlled vacuum measurement, variable detector bias supply (switchable positive or negative), preamplifier, test pulse generator with variable amplitude, and a leakage current monitor. The Alpha Duo has dedicated independent MCAs to optimize processing time.

Alpha Mega
       Benchtop single alpha spectrometer with sample chamber designed for filters up to 4.18 inches (106 mm) in diameter. Based upon the Alpha Duo, but capable of sampling much larger samples and using large diameter detectors, it has all the same quality features and is fully computer controlled. The Alpha Mega is available in benchtop form, or as an option in our Alpha Ensemble chassis.

Alpha Ensemble
       Modular alpha spectroscopy system which may be configured with up to 4 modules in any combination of ALPHA-DUO-M1 and/or ALPHA-MEGA-M1 expansion modules. Each alpha spectroscopy module includes a vacuum gauge, variable detector bias supply (switchable positive or negative), preamplifier, test pulse generator with variable amplitude, self-controlled RCAP, and a leakage current monitor.

       Each expansion module has a separate vacuum control within an Alpha Ensemble configuration. The Alpha Ensemble may be either rack mounted or left in the table-top mounting enclosure in which it is supplied. In the Alpha Ensemble configuration, an internal USB hub provides connection via a single cable to the user’s PC. Each detection system has individual digital offset and conversion gain settings for maximum flexibility.
