“…[8]) or novel medical gamma cameras (e.g. [9]). Since the simulation of the flood field data and the data processing with the adaptive algorithms can be performed within the same package, the users have a simple opportunity to evaluate performance of the adaptive algorithms for a custom detector configuration.…”

The software package ANTS (Anger-camera type Neutron detector: Toolkit for Simulations), developed for simulation of Anger-type gaseous detectors for thermal neutron imaging was extended to include a module for experimental data processing. Data recorded with a sensor array containing up to 100 photomultiplier tubes (PMT) or silicon photomultipliers (SiPM) in a custom configuration can be loaded and the positions and energies of the events can be reconstructed using the Center-of-Gravity, Maximum Likelihood or Least Squares algorithm. A particular strength of the new module is the ability to reconstruct the light response functions and relative gains of the photomultipliers from flood field illumination data using adaptive algorithms. The performance of the module is demonstrated with simulated data generated in ANTS and experimental data recorded with a 19 PMT neutron detector. The package executables are publicly available at http://coimbra.lip.pt/~andrei/

“…Furthermore, BGO provided low photon count rate due to the small light yield. The energy resolution was poor (about 18% for 511 keV) compared to the array type, but it showed good linearity for the energy spectrum obtained with a single type of compact dimension [8] . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 Therefore, the sensitivity of the detector was compared according to the geometrical location of the source [2].…”

Next-generation compact radiation detector was studied for more accurate measurement of radiation and improvement of reliability of the detector with purpose of developing of radiation protection technology and military application. The radiation detector which was used previously had some limitations due to the bulky size, limited range and the environment of radiation measurement. On the other hand, the compact radiation detector under this study which has adopted the silicon photomultiplier seems to be suitable for the application because of its physical excellence which are characterized by its small size, high sensitivity and durability. Accordingly, a SiPM based Scintillation detector has been made as a part of basic study of military radiation detector development. The detector has been tested for obtaining the operating characteristics of a sensor and analyzed with variation of parameter values and the efficiency of detection in accordance with the factor of measurement environment of radiation. The two SiPM based Scintillation detectors with the LYSO, BGO and CsI:Tl scintillator were made and the detectors were analyzed with the variation of operating characteristics as reverse bias, operating temperature and high magnetic field that are depend on environmental changes of radiation measurement. The results of three scintillators for a photon count rate and spectra were compared with each other. It was found that there are variations of radiation detection which are characterized by reverse bias, temperature and high magnetic field. Also, It was found that there were the 11.9 % for the LYSO, 15.5 % for BGO and 13.5 % for CsI:Tl energy resolution using array SiPM, and 18 % for CsI:Tl energy resolution using single SiPM, respectively when we measured energy resolution of 511keV for ²²Na. The results demonstrate the potential of SiPM based compact radiation detector to be used widely for Homeland Security applications.Index Terms-Silicon photomultiplier (SiPM), lutetium yttrium oxyorthosilicate (LYSO), bismuth gemanade (BGO), thallium doped cesium iodide (CsI:Tl), reverse bias, temperature, magnetic field, photon count rate, energy resolution, direction, homeland security applications.
