- Abstract
- Begun in 2010, the Lund-York-Cologne-CAlorimeter, LYCCA, collaboration is targeted at discovering exotic nuclear reaction products whilst implementing the possibility of both position tracking and measuring residual energies of relativistic particles. Each LYCCA module is composed of a double sided silicon detector and 9 CsI(Tl) detectors. This project is primarily focused on the Si detectors, the main aim being charaterization of 10 such modules and making sure they are in satisfactory condition to be delivered to FAIR. Values for the leakage current at full depletion voltage were recorded and energy resolution were extracted. In addition to this, 18 32-channels Cologne-produced preamplifiers were tested to ensure they are fully... (More)

In addition to this, 18 32-channels Cologne-produced preamplifiers were tested to ensure they are fully functional. The data was acquired using a FEBEX-MBS fully digital data acquisition system and calibrated using a Gnuplot script. The energy resolution per strip on both p- and n- sides as well as the energy resolution as a function of energy were extracted using python. All 10 LYCCA modules tested in this work fulfilled the requirements in both energy resolution and leakage current and are fit for experimental use. (Less)
- Popular Abstract
- Double Sided Silicon Strip detectors (DSSSDs) are crystalline wafers used to detect charged particles such as exotic isotopes produced in nuclear reactions. They are used here as part of a modular detector array called the “Lund-York-Cologne-Calorimeter” (LYCCA), which aims to help shed light onto fundamental questions of physics and early conditions of the universe. In this work, 10 DSSSDs are tested and certain characteristics are extracted; such as the leakage current and energy resolution, which play an important role in identifying reaction products. This is done by collecting data from a radioactive source on each DSSSD and processing it using various programmes. The data showed that all 10 DSSSDs have a sufficient energy resolution... (More)
