ORTEC’s
DSPEC
(pronounced D–Spec) is an industry first — the first integrated, digital-
signal-processor-based, digital gamma-ray spectrometer for use with all types of germanium
detectors, including super-large detectors.
DSPEC combines all the best features of low- and high-rate analog systems in a single, PC-
based package that is easily connected to local area networks (LANs). This highly automated,
yet flexible, hardware and software combination is suitable for most spectroscopy applications.
From all sides, environmental measurement through physics research to on-line industrial
measurements, the question has often been posed: “Why can’t one system provide the best in
resolution, throughput, and stability simultaneously? Why do we always have to make a less-
than-ideal compromise when the detector itself is capable of more performance?” Until now,
these questions have remained unanswered. Now DSPEC provides those answers:
In Environmental Counting, DSPEC provides extremely high stability over long counting
times. DSPEC solves the ballistic deficit problem that often degrades the resolution of large
HPGe detectors. It delivers the best resolution of which any detector is capable. A
statistical
preset optimizes sample throughput, and delivers lower cost per sample
.
DSPEC is
highly automated
, ending forever the need to use screwdriver or oscilloscope to
achieve the best performance.
Recognizing that not all counting rooms provide “laboratory conditions,” DSPEC also
provides
unprecedented temperature stability
for varying ambient temperature.
For applications involving high or widely varying count rates — such as intermediate-level
waste measurement or post accident sampling — DSPEC has
unmatched count-rate stability
in both peak position and resolution.
For industrial applications and when LANs are a requirement, DSPEC’s
built-in Ethernet
port
allows direct connection to the network. No other integrated instrument can do this.
Those wanting to wring the last drop of resolution performance from their detector will
appreciate the
built-in InSight
™
“Virtual Oscilloscope.”
DSPEC is a truly unique package, providing real benefits “where it counts,” for all gamma
spectroscopy operations:
