Capacitive Coupling

This folder contains example files and configuration for the CapacitiveTransfer module.

The capacitive_coupling.conf configuration file, as it is, simulates 6 FE-I4b planes (aligned as in a telescope) with a FE-I4b as a device-under-test (DUT) between the 3rd and 4th telescope planes. This geometry is defined in the ccpd_example_detector.conf file. The SimpleTransfer module is used for the telescope planes while the CapacitiveTransfer module is used for the DUT. The DUT is simulated with specific angles, nominal and minimum gaps, obtained from real measurements. The simulation results, regarding the DUT, should present a lower efficiency on the bottom left corner of the DUT due to the increasing gap between the pixels, towards this direction, and consequently a smaller coupling capacitance. The coupling capacitance for each gap is retrieved from the gap_scan_coupling_sim.root ROOT file. More information are provided in the CapacitiveTransfer module documentation.

The capacitance_matrix.txt file contains a generic relative coupling matrix (same as in the configuration file) that can be used to simulate the cross-coupling effects in parallel CCPDs assemblies. More information on possible configurations of the CapacitiveTransfer module are provided in its documentation.
