MEGA/DUO/Ensemble：

Alpha-DUO is a complete two-way alpha Spectrometer, used with traditional sample preparation methods alpha analysis of samples;Alpha-MEGA is a complete one way alpha Spectrometer, its shape and size are equal to Alpha-DUO, due to the enlarged measurement chamber and the possibility of using the largest3000mm2 detector, which is designed for direct measurement of the maximum 106mm diameter filter paper membrane sample.

Ensemble is a standard design that accommodates up to four or-DUO, or-MEGA, or a combination thereof.

-DUO and-MEGA Can work independently or embedded Ensemble Multiple channels are formed in the host alpha spectrometer.

Structural characteristics and performance indicators:

Detector area optional 300 /450/490/600/900/1200 mm²;The sample diameter can be obtained from 13mm to 51mm. Detector and measuredThere are 10 The gear distance is optional. The distance difference between two adjacent gears is 4mm, The maximum distance can be reached 44mm。

wan is fully digital and each channel is completely independent MCA, all parameters are controlled by computer.（Alpha Aria Vacuum control from outer panel） Vacuum Gauge: Range 10mTorr Arrive 20Torr。

Detector Bias: Range 0±100V, Size and positive and negative polarity are adjustable. Leakage Current Detector: Range 0 Arrive 10,000nA, display pointsresolution 3nA。

pulse generator; range 0 Arrive 10Mev, stability<50ppm/ºC , the pulse amplitude is adjustable.

Digitization MCA: System conversion gain can be set through software(Number of tracks)for 256、512、1024、 2048 or 4096 Tao, fine tuneThe gain is 0.25 Arrive 1; Gain stability: ≤150ppm/ºC;Conversion time of each event(dead time)：<2 µs 。

Digital spectrum stabilization,ADC zero point(ZERO)and lower threshold(LLD)All settings are adjusted by computer. The detector bias and leakage current of the spectrometer can be displayed numerically and graphically on the relevant software interface.

Input power:120/240 V ac, 50/60 Hz Input power 50W。

Communications:USB2.0 interface. every Alpha Ensemble Finally provide a cable toPC。Application software:MAESTRO-32 or AlphaVision

Ensemble-8 Dimensions:48.5cm W× 49.2cm D × 27.2cm H;Net weight:26.6 kg； working conditions: temperature 0ºC Arrive 50ºC, relative humidity ≤ 95%。

Resolution and background: based on usage 450mm² ULTRA-AS detectors and high quality ²⁴¹Am Point source, energy resolution(FWHM):≤20KeV (The distance from the detector to the source is equal to the diameter of the detector), detector efficiency:  ≥25% (The distance from the detector to the source is less than 10mm), background: in 3MeV above, Count per hour≤1。

The resolution of several other detectors (@5.486MeV）：

ENUS-490，FWHM): ≤ 22KeV； ENUS-600，FWHM): ≤ 24KeV； ENUS-900，FWHM): ≤ 29KeV； ENUS-1200，FWHM): ≤ 37KeV

Ensemble/DUO/MEGA The recoil suppression function has been implanted, you only need to configure the recoil suppression function   plate RCAP-ST This function can be realizedfunction, thereby avoiding as much as possible the detector and cabin from being alpha Particle contamination.
