Installation and calibration of a HPGe detector in a deep underground facility
(2002)Medical Physics Programme
- Abstract
- The aim of this thesis work has been to set up an ultra low-level gamma-ray spectrometry system in the underground laboratory HADES and applying the system to measurements of activation products in tantalum discs in order to determine low neutron fluxes. The main part of the work has been the efficiency calibration of the detector and the implementation of a computermodel for Monte Carlo simulations of the detectors full energy peak efficiency in different source-detector geometries.
- Abstract (Swedish)
- Den här uppsatsen handlar om installationen och kalibreringen av en halvledardetektor i en underjordisk anläggning. Avsikten men att placera sin detektor långt ner under markytan är att minimera inflytandet av den kosmiska bakgrundsstrålningen. I kalibrerings förfarandet konstruerade vi en datormodel av detektorn. Med denna datormodel kan man simulera effektivitetskalibreringen av olika strålkälla-detektor geometrier, vilket underlättar om man behöver mäta prover av många olika storlek och form.
