“…Higher resolution spectral data (e.g., from high-purity germanium, HPGe, detectors) are conventionally considered more suitable for radioisotope identification but in many situations, particularly in field applications, a poorer resolution detector (such as NaI(Tl) and LaBr 3 scintillators) equipped with a proper isotope identification algorithm are used. 3,4 In the development of an RIID both the detector and identification algorithm must be considered, because they depend on each other.…”

“…Two components are essential for a RIID 2 : (a) a detector measuring good quality spectra (high energy sensitivity, high energy resolution and small spectral artifacts or distortions) and (b) software able to match the characteristics of the spectra obtained by a given detector (measured spectra are always detector dependent). Higher resolution spectral data (e.g., from high‐purity germanium, HPGe, detectors) are conventionally considered more suitable for radioisotope identification but in many situations, particularly in field applications, a poorer resolution detector (such as NaI(Tl) and LaBr 3 scintillators) equipped with a proper isotope identification algorithm are used 3,4 .

This is a computational study to develop a rugged self-powered Radioisotope Identification Device (RIID). The principle of operation relies on the High Energy Current (HEC) concept (Zygmanski and Sajo, Med Phys. 43 4-15, 2016) with measurement of fast electron currents between low-Z and high-Z thin-film electrodes separated by nanoporous aerogel films in a multilayer detector structure whose prototypes were previously investigated (

“…Its excellent timing properties (down to 100 ps in optimal conditions [2][3][4]), temperature stability [5,6] and high energy resolution for a scintillator (3% at 662 keV [7,8]), which is dominated by statistical contributions [9], have made LaBr 3 :Ce the material of choice for many nuclear physics experiments including γ-ray spectroscopy [10,11], medical imaging [12,13] or industrial applications [14,15]. The high light yield (165% of that of NaI) and the very short scintillation light decay constant (between 20 and 30 ns [5,6]) pose LaBr 3 :Ce as a well suited candidate material to allow γ-ray spectroscopy at very high count rates.…”

The applicability of LaBr 3 :Ce detectors for high count rate γ-ray spectroscopy is investigated. A 3"x3" LaBr 3 :Ce detector is used in a test setup with radioactive sources to study the dependence of energy resolution and photo peak efficiency on the overall count rate in the detector. Digitized traces were recorded using a 500 MHz FADC and analysed with digital signal processing methods. Good performance is obtained using standard techniques up to about 500 kHz counting rate. A pile-up correction method is applied to the data in order to further improve the capabilities at even higher rates with a focus on recovering the losses in efficiency due to signal pile-up. It is shown, that γ-ray spectroscopy can be performed with only moderate lossen in efficiency and high resolution at count rates even above 1 MHz and that the performance can be enhanced in the region between 500 kHz and 10 MHz by using the applied pile-up correction techniques.
