Simulation of 4 HPGe Compton-Suppression spectrometer

The DGF Pixie-4 spectrometer – Compact Digital Readout Electronics for HPGe Clover Detectors

Large volume HPGe detectors are commonly used in applications that require good energy resolution and high detection efficiency, but are expensive and difficult to grow. Clover detectors consisting of 4 smaller crystals in a common cryostat are a possible alternative, but traditionally require complex readout electronics. In contrast, the DGF Pixie-4 is a compact, digital spectrometer providing...

Performance of the Compton Spectrometer at HARWI/HASYLAB*

Performance, resolution and spectral throughput both of the sagittally focusing monochromator and of the alternately installed two analysing systems, a Cauchois-type cylindrically bent crystal analyser for Compton-profile measurements, and a spherically bent crystal analyser for S(q, (^-measurements, of the new Compton spectrometer at the HARWI (harter Röntgen Wiggler) of the DORIS storage ring...

Search for the radioactivity of 180mTa using an underground HPGe sandwich spectrometer.

The radioactivity of (180m)Ta has never been detected. The present attempt to detect it was carried out using a newly developed HPGe sandwich spectrometer installed 500m water equivalent underground in the HADES laboratory. The sample consisted of 6 discs of tantalum of natural isotopic composition with a total mass of 1500 g and a total mass for (180)Ta of 180 mg. The sample was measured for 6...

Developments in High-Performance HPGe Detector Spectrometer Systems for Safeguards Applications

Both fixed and portable safeguards applications place stringent demands on spectrometer systems. Instruments must perform well spectroscopically despite operation in harsh environments. Resolution and stability requirements for Pu isotopic systems hardware are based on the complexity of the spectrum and the necessity for the analysis software codes to use multipeak regions of the spectrum.
