The eMorpho is the
smallest, fastest, USB-powered single-card
MCA currently on the market. At only 2-inch
by 2-inch, and a very competitive price, the eMorpho
is an ideal solution for standalone and embedded
applications. The device is entirely controlled and
powered through its USB port. Using
real time digital signal processing the
eMorpho achieves unrivaled processing speed, up to
16 Mcps, and can accommodate any known
scintillator.
 Beyond spectroscopy, the
eMorpho offers built-in extended
functionality such as waveform capture for
diagnostics, real time pulse shape analysis for phoswich
detectors and list mode data acquisition for monitoring
systems. 13 general purpose I/O lines support
daisy-chaining of clocks, triggers and data
for use in detector arrays such as radiation portal monitors.

The TwinBase product line
introduces the next generation of advanced embedded
PMT HV-supplies. The TwinBase pairs up a high voltage
generator with a very low power transistorized high voltage
divider to energize the photomultiplier dynodes. This ensures
a perfect match between these crucial components creating the
best possible system performance.
 The TwinBase
provides exceptional linearity and gain
stability while drastically cutting power
consumption. The TwinBase is the
ideal solution for battery-operated systems that have to
perform reliably and with accuracy under high-count rate
conditions.
Using the TwinBase eliminates the need for
external high voltage supplies and high voltage cables. This
reduces system complexity, improves reliability,
ruggedness and safety.

The R2D nuclear radiation
sensor utilizes a matched scintillator crystal
and photomultiplier combination, powered by a
TwinBase and read out by an eMorpho
digital MCA. The R2D sensors use a single
USB interface for both, data and power. All components have
been selected and designed to optimize system
performance.
The R2D delivers stable and precise
high-speed spectroscopy even in intense radiation
environments, reducing operating costs
associated with measurement time. The sensors are delivered
with calibration data and a unique identifier stored in
non-volatile memory. As there are no manual adjustments
necessary, sensors can be deployed by minimally trained
personnel.
The R2D
sensors are sold with a variety of crystals, such as NaI(Tl)
and CsI(Na), suitable to different application. All sensors
are fully characterized at the factory and
carry a performance guarantee. The sensors
have built-in support for array applications, such as
radiation portal monitors. The combination of these features
makes the R2D an outstanding solution for a
wide range of applications.

CsI-Advantage
is a class of R2D detectors with extraordinary energy
resolution, typically 5.6% fwhm at 662 keV.
Better energy resolution, paired with the high stopping
power of CsI, translates into higher sensitivity and
shorter counting times. Unlike LaBr3, CsI(Na) is
free of any radioactivity and very suitable for low-background
counting-where achieving the highest sensitivity is of ultimate
importance.
We have achieved this outstanding performance by using
off-the-shelf, but select-grade, crystals and highly
gain stable and linear PMTs. We have created special eMorpho
units in which analog signal conditioning and digital
signal processing are optimized for CsI(Na)light pulses.
In order to maintain and guarantee this performance in the future
we are working closely with the manufacturer on establishing
a crystal selection procedure exclusively for the CsI-Advantage
detector series.

The muon counters
are a complete system for safe and reliable muon detection
and measurement. Two standard configurations are available,
using either one or two paddles.
A muon counter system includes one or two paddles, HV supplies
and an eMorpho for data acquisition. The entire system is
powered and controlled via a USB port on a PC or laptop.
The muon counters are a great tool for serious science as
well as for teaching cosmic radiation physics, particle physics
and statistics at various levels of understanding.
The included software features a graphical user interface,
which allows students to immediately observe cosmic radiation.
An oscilloscope-like display shows the photo-multiplier pulses
as the muons pass though the scintillator. Students can observe
single and coincidence traces and can even observe muon decay
live on their computer screen.
