Silicon photomultipliers (SiPM) are becoming more and more popular in different fields of physics. The use of SiPM arrays requires a data acquisition (DAQ) system capable of reading multiple channels for each event. A DAQ system for the control and the readout of 64-channel detectors was designed and fabricated. Significant improvements in performance and new functionalities have been done. The performance...
A three layer Compton telescope for dose monitoring in hadron therapy is under development at IFIC - Valencia. It will consist of three detector layers and each layer will be made of a continuous LaBr3 crystal coupled to four Silicon Photomultiplier (SiPM) arrays. A prototype made of two detector layers has already been assembled and tested. The detector layers consist of a 32×36×5 mm3 and 32×36×10...
Detection and spectroscopy tests of the first functional unit of a self-dependent silicon detection module constructed on the base of micro-cable and TAB technology are presented. The tests were performed using pulse-height analysis of the signals induced by gamma rays in the silicon sensor. Good shapes of the spectra and satisfactory spectroscopy resolution (given by FWHM which is less than 2 keV)...
This paper describes DAQ++, a C++ based framework for developing data acquisition software. The design of DAQ++ is fully object oriented (OO) and provides a hierarchy of objects that allow a full control of the acquisition system and, also, on-line monitoring and storage of data. Being an OO system, it is easy to extend the DAQ system over several machines using a CORBA based architecture which is...
