1. 1. Dosimetric Characteristics of CVD Single Crystal Diamond Detectors in Radiotherapy Beams

   University essay from Medicinsk strålningsfysik (tills m KI)

   Author : Anna Ärlebrand; [2008]
   Keywords : Diamond detector; CVD; Priming dose;

   Abstract : Dosimetric characteristics of a CVD single crystal diamond detector have been evaluated. Detector stability, linearity, optimal bias, temperature dependence, directional dependence, priming and pre-irradiation behaviour, depth dose curves and dose profiles were investigated. The optimal bias was determined to be 50 V. READ MORE

3. 2. Determination of the effective volume of a detector

   University essay from Medicinsk strålningsfysik (tills m KI)

   Author : Jonas Grafström; [2007]
   Keywords : Gamma knife; Semi conductor; Detector; Effective volume; 60Co;

   Abstract : A method to establish the boundaries of the sensitive volume for a chosen detector to within 50µm (as specified by Elekta Instuments AB) was investigated and is presented in this project. The detector studied was fixed to a positioning system with possibility to move with sub micrometer increments, and scanned in a narrow photon field. READ MORE
