Monte Carlo simulations are used to test the Pulse Shape Comparison Scanning (PSCS) technique implemented at the IPHC scanning table . The tests, performed on a high purity germanium (HPGe) detector unit of the AGATA array, aim to quantify the accuracy of the system and validate it. The simulations use a combination of tools such as Geant4, SIMION and the Agata Detector Library (ADL). Quality parameters are extracted at various gamma-ray energies and the impact of the input statistics on the parameters is also analyzed.

“…However, some characteristics of the detectors such as the real impurity distribution and the thickness of the dead layers are not always correctly known and their implementation is subject to uncertainties. A novel approach to database construction is the implementation of full volume characterization of the detectors via three-dimensional scans realized with dedicated tools called scanning tables [17][18][19][20]. A first kind of such tables [17,18] performs scans of germanium detectors by irradiating them from below with a collimated gamma-ray source.…”

“…A second kind of scanning tables [19,20] make use of the two 511 keV gamma rays emitted back-to-back from the β + decay of a 22 N a source to determine precisely the emission direction with an imaging detector. The scanned germanium detector is exposed two times from two orthogonal directions and the database is built by reconstructing off-line the position of crossing interacting gamma rays (voxels of ∼ 8 mm 3 ).…”

Scanning tables use collimated gamma-ray sources to perform full volume characterization of position sensitive detectors. One of such tables is hosted at IPHC Strasbourg. It was designed and built within the AGATA collaboration. It exploits the Pulse Shape Comparison Scanning (PSCS) technique to build databases of pulses used to characterize the response of high purity germanium (HPGe) detectors and perform R&D on such crystals. Ultimately, measured databases could be used by the pulse shape analysis (PSA) algorithms employed in AGATA experiments. The table can perform full volume scans of large volume detectors in short times, with a good spatial resolution and at different energies. Lately, the table was upgraded with a new 152 Eu source, which emits gamma rays in cascades of different energies. A scan with such source is performed for the first time. It allows to build different energy databases in one single scan. The present work aims at testing the performances of the PSCS technique with a multienergetic source and verifying some assumptions of the Shockley-Ramo theorem which are at the base of the PSA algorithms used for gamma-ray tracking arrays.

A methodology including software tools for analysing NORM building materials and residues by low-level gamma-ray spectrometry has been developed. It comprises deconvolution of gamma-ray spectra using the software GALEA with focus on the natural radionuclides and Monte Carlo simulations for efficiency and true coincidence summing corrections. The methodology has been tested on a range of building materials and validated against reference materials.
