Our Background

Amptek was founded in 1977 by Alan C. Huber and John A. Pantazis to fulfill the needs of space instrumentation for off-the-shelf, high performance, high reliability, small size and low power dissipation instruments and components. Shortly thereafter, Amptek hybrid preamplifiers became the standard for the space industry as they were used worldwide by instrument makers in both Earth satellites and deep space probes. In 1986 Amptek expanded to designing and manufacturing full satellite instruments. Numerous plasma analyzers, electron and ion detectors, and radiation monitors have been developed by Amptek and flown in both military, research, and commercial spacecraft. Amptek designed and built 42 complete space instruments.

Amptek applied its experience and knowledge of high performance space instruments to developing commercial radiation detectors and electronics in the 1990’s. In 1994 it received the R&D 100 award for the XR-100 X-Ray detector as one of the years most technologically significant products. The XR-100 opened new markets as the technology was both cost effective and portable. In 1996 it was selected for the Mars Pathfinder Mission and landed on Mars on July 4th, 1997. By 2003 the XR-100 was the standard in the industry. It is now the foundation for the most widely used X-Ray detectors for XRF in the world.

On August 4, 2014, Amptek was acquired by AMETEK, Inc. where it is now a unit of the Materials Analysis Division.

Space Related Products

Over the years many of Amptek's products have been selected for spaceflight applications.  Amptek products chosen for spaceflight missions include hybrid preamplifiers, front-end electronics, plasma analyzers (ESA), radiation monitors/dosimeters (CEASE), and of course, our x-ray detectors and digital pulse processors. This link has examples of specific missions where Amptek products were flown.

Commercial Products

Our Products are used by researchers, educators, scientists, and OEMs to measure X-Rays, Gamma rays, and for other applications.

XR-100 X-Ray Detector

Taking advantage of its experience in building hybrid circuits and satellite instrumentation Amptek developed the XR-100 X-ray detector for commercial use. After winning the coveted R&D 100 award in 1994, this simple to use, thermoelectrically cooled X-Ray detector has been the technological breakthrough responsible for replacing cumbersome liquid nitrogen cooled detectors in many applications. Although developed for commercial use, the XR-100 was selected for the Pathfinder Mission to Mars where it successfully analyzed rocks and soil using X-Ray Fluorescence techniques (XRF). This successful instrument is the detector of choice in numerous Original Equipment Manufacturers’ (OEM) applications using the XRF method.

When Amptek began development of the thermoelectrically cooled detector there was virtually no hand-held or portable XRF market. No cost-effective technology existed with good enough performance in a small enough package that could be incorporated into a portable XRF analyzer. As the detector resolution improved, more applications emerged and the XR-100 series became the standard of the industry. The thermoelectrically cooled detector has lowered the cost of XRF analysis, therefore providing access to the technique to markets and users never before thought possible by the analytical industry. With a low cost, high performance solution, XRF will expand and find new markets and applications as technological challenges demand innovative and reliable solutions.

DPP Digital Pulse Processors

The Amptek DPP is a state of the art, high performance, low power digital pulse processor. It digitizes the preamplifier output signals, replacing both the shaping amplifier and MCA in a traditional, analog spectroscopy system. The DPP offers several clear advantages over traditional systems, including improved performance (very high resolution, reduced ballistic deficit, higher throughput, and enhanced stability), enhanced flexibility, low power consumption, small size, and low cost. 

X-123 X-Ray Detectors

Amptek's X-123 represents the culmination of x-ray detector development at Amptek.  The X-123 detectors are small and require low power but provide high performance data all while still being simple to operate. The X-123 exemplifies this Amptek philosophy by providing in a single package, the x-ray detector, its charge sensitive preamplifier; the DP5 Digital Pulse Processor with pulse shaper, MCA, and interface; and the PC5 Power Supply. All that is needed to operate the complete x-ray spectrometer is a 5 Volts DC input and a USB, ethernet or RS232 connection to your computer.
