The Cryogenic Dark Matter Search (CDMS) is an experiment to directly detect dark matter, a mysterious substance that makes up the majority of the matter content in the Universe and has so far only been observed due to its gravitational effects. CDMS uses high-purity Ge (HPGe) crystals as detectors for dark matter in the form of weakly interacting massive particles (WIMP). In order to reduce sys...

Abstract A standard procedure for characterizing the high-purity germanium detector (HPGe), manufactured by Canberra Industries Inc [1], is performed directly company using patented methods. However, usually expensive and must be repeated because characteristics of HPGe crystal change over time. In this work, principles a technique are developed use in obtaining optimizing based on cost-effecti...

This document contains a proposal of the BEPC-II collider beam energy calibration system (IHEP, Beijing). The system is based on Compton backscattering of carbon dioxide laser radiation, producing a beam of high energy photons. Their energy spectrum is then accurately measured by HPGe detector. The high-energy spectrum edge will allow to determine the average electron or positron beam energy ε ...

One of the goals of hypernuclear physics is to study the properties of baryon-baryon interaction including the strangeness contribution. Double hypernuclei can provide information about the ΛΛ interaction in addition to the hyperon-hyperon and hyperon-nucleus one. A new technique for producing double hypernuclei using antiprotons is foreseen in the PANDA experiment at FAIR. Gamma ray spectrosco...

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...
