Monte Carlo performance study for the PANDA MVD — •Simone Bianco1,2, Elena Botta1, Kai-Thomas Brinkmann2, and Thomas Würschig2 — 1Università degli Studi di Torino — 2HISKP - Universität Bonn
The Micro Vertex Detector is the innermost component of the PANDA spectrometer. Therefore it is important to understand its influence on particles crossing it. The material budget introduced by active elements (the sensors) and the passive ones (frontend electronics, cooling, support structures, signal and supply cables) must be mapped and taken into account while simulating events in PANDA. This work is showing the implementation of a detailed geometry where all the components of the MVD were introduced. This geometry was later on used to perform simulations in order to evaluate the effect of Coulomb multiple scatterings. Both the barrel part and the forward arm of the tracking system were analyzed. The final result of these simulations is a full scan with different particles (protons, muons, pions and electrons) of the track displacement introduced by the presence of the MVD using different initial momenta. The second part of the talk will address the solid angle coverage of the MVD. Using a dedicated tool a highly detailed definition of the sensors was introduced in the simulations. The coverage of the detector was studied as a function of the initial direction of the particles, their momentum, charge and mass. Both a qualitative and a quantitative analysis were realized.
