XIA LLC (formerly X-Ray Instrumentation
Associates) produces advanced X-ray and gamma-ray detector electronics
and related instruments with applications in research and industry.
The introduction of digital signal processor
(DSP) technology has revolutionized the field of X-ray and gamma-ray
spectroscopy, and X-ray Instrumentation Associates (XIA) has been
at the forefront of this revolution since the beginning.
For nearly a decade XIA has pioneered the use of DSP and field-programmable-gate-array
(FPGA) technologies working in concert to produce the fastest
and most powerful spectrometers on the market. In our patented
core technology, a reconfigurable FPGA carries out the brute-force
work of FIR shaping and pileup detection, reducing the digitized
raw detector signal to a few user-defined metrics per detected
event, and thus freeing the DSP to carry out various high-level
post-processing functions to produce spectra of very high quality
while dramatically boosting throughput.
XIA offers a full range of spectrometers,
separated into two categories:
The Digital X-ray Processor (DXP)
series is used by researchers and companies worldwide for XRF,
EDX, and XAFS materials analysis.
The Digital gamma-ray
processor (DGF) series is used for general gamma-ray
spectroscopy, coincidence spectroscopy and for instrumenting entire
nuclear physics experiments.

a detailed comparison of the DGF and DXP instruments.
Both series are available in three form factors:
- Single-channel benchtop spectrometers for top performance.
- Compact independent or integrated multi-channel spectrometer
systems for multi-element detectors, including segmented HPGe-detectors.
- Miniaturized autonomous single-channel spectrometers for low
power, hand-held, and embedded applications.
XIA can readily modify its standard products
to meet individual or OEM applications. Our hardware can be adapted
to fit specific size, shape, temperature range, I/O protocol and
power requirements if necessary. However, most adaptations require
only firmware or software changes, since all signal processing
is accomplished digitally in our spectrometers. This flexibility
reduces cost and time to market; and, as your needs evolve, so
too can the software. For instance, we can adapt the on-board
software to integrate auxiliary control signals, to customize
trigger and coincidence decisions, and to calculate derived quantities
on-line. The built-in pulse shape analysis capability has been
used for 3D position reconstruction in coaxial segmented HPGe-detectors,
for neutron/gamma discrimination in NE213 and
for alpha/gamma/neutron particle identification using CsI(Tl).
Finally, if you have a problem whose solution
requires a really unusual combination of capabilities, we can
design a completely customized solution based upon our proven
core technologies that will cost effectively provide world class
performance.
