The Amptek PX5 interfaces between (1) an X-ray and gamma-ray detector with its preamplifier and (2) a computer running data acquisition and control software. Designed principally to support Amptek’s XR-100 series of SDD, Si-PIN, and CdTe detectors, it can be used with many other radiation detectors and preamplifiers, including HPGe detectors and scintillators. It is compatible with both reset and feedback preamplifiers of either polarity. The PX5 includes (1) a high performance digital pulse processor (replacing a conventional shaping amplifier), (2) a multichannel analyzer, and (3) both low and high voltage power supplies (±HV).
The PX5 offers several advantages over traditional systems, including improved performance (very high resolution, reduced ballistic deficit, higher throughput, and enhanced stability), many more configuration options to optimize the system, and many communications and output options. The PX5 is based on Amptek’s latest generation of digital pulse processing technology, also used in the DP5 family of products.
The signal input to the PX5 is the preamplifier output. The PX5 digitizes the preamplifier output, applies real-time digital processing to the signal, detects the peak amplitude (digitally), and bins this value in its histogramming memory, generating an energy spectrum. The spectrum is then transmitted over the PX5’s USB, Ethernet, or RS-232 interface to the user’s computer.
The PX5 is compatible with both 32 and 64 bit operating systems, including Windows 10.
Features- Single unit compatible with all current Amptek SDD, Si-PIN, and CdTe detectors
- Includes
- Digital pulse shaping amplifier
- Integrated multichannel analyzer
- Power supplies
- Supports detectors from other manufacturers, and both reset and feedback preamplifiers of either polarity
- Trapezoidal, and new Cusp shaping with wide range of peaking times to optimize performance
- High count rate capability with excellent baseline stability, throughput, and pile-up rejection
- Up to 8k output MCA channels
- Oscilloscope mode – DAC output for pulse monitoring and adjustment
- 8 single channel analyzer outputs
