XIA’s digital X-ray and Gamma-ray processors share much of their underlying architecture but are geared toward different applications. This page is intended to help customers decide which family of instruments is most appropriate for their application.

The X-ray processor employs a field programmable gate array (FPGA) as a ‘firm-wired’ yet fully programmable digital pulse shaper and pileup rejection unit in combination with a digital signal processor (DSP) that oversees pulse-height data collection according to user settings. Incoming data can be gated and resolved into separate banks of spectrum memory in real time as directed by external timing signals, allowing a wide variety of spectroscopy experiments, e.g. MCA and SCA mapping. The X-ray processor’s dead time per event is extremely low, yielding industry-leading output data rates of over 1,000,000 cps (in full MCA mode). Various time-resolved data acquisition modes make it a very powerful tool for XAFS and X-ray Mapping applications. In short, the X-ray processor family provides industry-leading performance at very high incident rates. Please visit the X-ray Products pages for further details.

The Gamma-ray processor family is intended for more sophisticated signal processing applications that require pulse-shape analysis and/or coincidence triggering. With the addition of a FIFO memory for digital signal capture and a flexible,  two-level triggering system that can span multiple modules, the DSP can not only make pulse-height measurements but can also work in real time on various user assigned pulse shape analysis tasks, such as real-time ballistic deficit correction. Incoming data may also be processed and sorted according to pulse shape information, e.g. rise-time, and further constrained by coincidence timing information from other detector elements in the system. XIA’s Gamma-ray processors pose solutions to a wide range of extremely demanding pulse processing applications in the areas of nuclear physics, strip detectors, and very high resolution gamma-ray spectroscopy. Please visit the Nuclear Products pages for further details.

The microDXP product spans both X-ray and Gamma-ray applications and is the natural choice for many handheld and portable Gamma-ray applications as well as X-ray. Whereas the microDGF is specifically designed for high-resolution HPGe Gamma detectors, the microDXP works with almost any preamplifier output signal, and is well suited for both Gamma-ray and X-ray applications requiring other detector types.

XIA’s X-ray and Gamma-ray instruments are available in several form factors, including PXI, PXI-Express, stand-alone modules with USB and Gigabit Ethernet, and as compact circuit boards for embedded OEM applications. Please contact XIA for help deciding which product is right for your application.
