IDM-200-V The IDM-200-V Interchangeable Detector Module from ORTEC is a high performance gamma-ray spectrometry “building block” for use in multiple applications. It is a completely self-contained package, comprising a single, large-area, mechanically cooled high-purity germanium (HPGe) detector of standardized crystal dimensions and all necessary spectrometry electronics in a RUGGED, low-power configuration. The IDM-200-V includes everything needed for the high resolution spectrometry task, producing either a resultant spectrum in memory or delivering a digitized pulse stream in list mode...

The ~50% relative efficiency HPGe detector in the IDM-200-V is of an “over-square” diameter-to-length profile. The large diameter enhances low energy efficiency. The figures below show the point source absolute efficiency curves of an IDM-200-V in comparison with a more conventionally profiled detector of almost the same relative efficiency (51%). The IDM-200-V shows much higher efficiencies at low to medium energies, where container or matrix absorption effects are possible to be problematic to measurements. See detailed specifications below for more information. Radiation Entrance Window:...

IDM-200-V Data Collection Modes Data are usually collected by the IDM-200-V in Pulse Height Analysis (PHA) mode and transferred to a PC for further analysis. There is a small dead time when the data are being transferred during which new data are not collected. If absolutely no loss of data is an essential need, then, a solution exists in the form of List mode acquisition. In the List mode of operation, data are stored directly to computer memory, event by event, with a time stamp (200 nanoseconds). These data can then be reconstructed into separate spectra by time, energy, or position....
