The EXOGAM clover detector consists of four high-purity germanium (HPGe) crystals in a common cryostat. Each individual crystal is electrically segmented into four regions. We propose a method based on a multidimensional fitting procedure to calibrate the energy from the segments. This method could be used for any kind of segmented germanium detector. Its application to the EXOGAM clover is dis...

Because of the major impact of the radioactive materials on the environment, their characterization methods have to be well defined, complete and agreed by the control bodies and the civil society. The paper presents measurements of certified etalon gamma emitting radiation sources, in order to perform the energy and the efficiency calibration of a new HPGe spectrometric system, and to determin...

With the goal of measuring precise gamma-ray intensities for short-lived (< 5 s) accelerator-produced activities, we have calibrated the efficiency of an HPGe detector between 53 and 1836keV to sub-percent precision with a combination of source measurements and Monte Carlo calculations. Using known or independently measured detector dimensions, we have achieved both relative and absolute agreem...

The first true coaxial 18–fold segmented n–type HPGe prototype detector produced by Canberra–France for the GERDA neutrinoless double beta-decay project was tested both at Canberra–France and at the Max–Planck–Institut für Physik in Munich. The main characteristics of the detector are given and measurements concerning detector properties are described. A novel method to establish contacts betwe...

A measurement station dedicated for quantitative radiological characterisation of naturally occurring radionuclides in a metallurgical company and based on gamma-ray spectrometry was developed. The station is intended for performing quality control of final non-ferrous metal products and for radiological checks of incoming materials. A low-background point-contact HPGe-detector was used and the...
