description: The subject of the graduate qualification work is âParameterization of the Tracking System Response for the SPD Experiment at the NICA Colliderâ. The given work is devoted to a realistic parameterization of straw tube signals of the SPD Straw Tracker using predictions of the Garfield++ simulation program. The work aims the following goals: 1. To study physical processes of gaseous detectors, in particular, of straw drift tubes. 2. To simulate processes of the straw response to a 1 GeV muon traversing the tube using the Garfield++ program for four boundary cases of possible magnetic field, 0 and 1.3 T, and the inclination angle of the charge particle tracks, 13â¦ to 90â¦, which will be realized in the SPD Straw Tracker. 3. To study the Straw Tracker electronics response for a given readout electronics modeled with LTSpics package for given input signals produced in the Garfield++ simulation. 4. To study influence of the realistic electronics noise and electronics thresholds on the performance of the Straw Tracker and to chose the safe threshold settings for the given readout electronics type. 5. To create parametrization of the most probable value and distribution width of time distribution representing the straw signal registration time. The work was performed on the premises of the Research Center KI PNPI and JINR where work on the SPD Straw Tracker development is ongoing. A realistic model of the Straw Tracker readout electronics was developed in JINR. Within the master thesis work, passage of the muons through a straw tube and straw signal formation was modeled with Monte Carlo methods using the Garfield++ package providing an input to the electronics model and the analysis. The analysis of the modeled signals was performed as well. As a result, the straw response time distribution was obtained as a function of the relative muon track coordinate and parameterized for further implementation into SPDroot, the software describing work of the SPD detector. Influence of the track inclination and magnetic field strength were studies as well.
