Alpha Suite

AlphaSuite
All-In-One Integrated Alpha Spectrometers
“Advanced Digital Alpha Spectrometers
to Meet Every Counting Laboratory Need.”
AlphaSuite
With the Alpha Suite range of integrated
Alpha Spectrometers, ORTEC is able to
address the needs of ANY counting
laboratory, large or small, upgrading or
just starting out. The latest advanced
digital design, together with a modular
mechanical approach, aligns value and
performance with unparalleled
configuration flexibility. Any of these
spectrometers may be added to existing
ORTEC systems simply by installing the
latest drivers included with the
instrument.
All Alpha Suite models feature the following:
• A complete instrument requiring vacuum, power and connection to a PC only.
• Simple, high speed USB connection to computer.
• Internal advanced DIGITAL MCA.
• Digital Spectrum Stabilizer.
• Computer controlled preamplifier, HV supply, and calibration pulser.
• High Quality Nickel-plated Brass Vacuum chamber, easily decontaminated
• Optional Alpha Recoil protection system available.
• Compatible with all previous ORTEC Alpha Spectrometer Systems.
• MAESTRO® MCA Emulation Software.
Alpha Aria®
A single alpha spectroscopy channel in a 2-wide NIM chassis. The digital MCA is built right in, so a USB
connection is all that is needed to start counting. A simple to operate PUMP/HOLD/VENT control is mounted
on the front panel. The Alpha Aria is easy to add to existing NIM installations.
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.
