Abstract
In this work, the required amount of protons needed to obtain a specific accuracy in the detection of 4.44MeV gamma rays in a carbon target has been determined for different parameters. With this information, a beam time plan can be composed to execute this experiment. This experiment is useful for the development of Positron Emission Tomography (PET)-verification in proton therapy and could compensate for the uncertainties proton therapy entails. Furthermore, the behavior of a PET detector was analysed when it was switched off and on. The recovery period of the PET detector can be divided into two phases. In the fast recovery period, which is about 0.5ms after the detector has been switched back on, the signal is unstable. In the beginning of the slow recovery period, which has a duration of approximately 25ms, the 511keV photon peak was positioned at a value of 488.1keV and this peak moves during the recovery slowly back to its original position.
