As demand increases for better and improved techniques for cancer treatment in Portugal, there is an ongoing discussion on the need to build a proton therapy center, as well as to train skilled workers in this field. As a result, there is the need for high precision measurement instruments that provide real-time absorbed dose measurements on the patients at tissue or DNA level.
The goal of the present work is to develop a new detector capable of measuring real-time absorbed dose with sub-millimeter resolution. The device is constructed using juxtaposed thin scintillating plastic optical fibers (SPOF) readout by a multi-anode photomultiplier (MAPMT, 64 channels) and a suitable data acquisition (DAQ) system. In this article, we discuss the characterization of the full detection chain: SPOFs, MAPMT and DAQ.
