Digital X-ray Processor (DXP) and Digital
Gamma Finder (DGF) share much of their underlying architecture but
are geared toward different applications. This brief description is
intended to help customers decide which family of instruments is most
appropriate for their application.
The DXP 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 mapping and SCA
mapping. The DXP's dead time per event is extremely low, yielding industry-leading
output data rates of over 700,000 cps (in full MCA mode!). In short,
the DXP is a versatile digital spectrometer with industry-leading performance
at very high incident rates. Please visit the DXP
Products pages for further details.
The DGF 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 DGF's 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 realtime ballistic deficit correction. Incoming data may also
be processed and sorted according to pulse shape information, e.g. risetime,
and further constrained by coincidence timing information from other
detector elements in the DGF system. The DGF poses 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 DGF Products
pages for further details.
