Description
PARSIFAL (PARametrized SImulation) is a software tool designed to reproduce the complete response of Gaseous Detectors. It models the involved physical processes through simple parametrization, thus achieving a fast processing times. Existing software, such as GARFIELD++, while robust and reliable, is highly CPU time-consuming. The development of PARSIFAL is motivated by the need to significantly reduce processing time without compromising the precision of a full simulation. A set of parameters, extracted from GARFIELD++ simulations, are used as input, allowing PARSIFAL to run independently. By sampling from parameterized distributions, PARSIFAL can rapidly simulate high-statistics samples, integrating various steps including ionization, diffusion, multiplication, signal induction, and electronics. For the µ-RWELL, the effect of the resistivity layer on the charge spread on the readout has been incorporated, following the treatment proposed by M.S. Dixit and A. Rankin.
PARSIFAL is used to simulate MPGDs, specifically triple-GEM and µ-RWELL chambers. Initially, the results were tuned to match experimental data from test beams using the APV-25 frontend readout by the SRS system, which was simulated within the code. The same procedure was later applied to more modern electronics, namely the TIGER ASIC and the GEMROC system. This new electronics package was implemented in PARSIFAL, and a tuning of the simulated data to real experimental results was performed. This contribution will present the full code, focusing on its latest implementations and a comparison with experimental data obtained from the $\mu$-RWELL.The tuned simulations are now being used for the optimization of new readout electronics. This involves simulating and analyzing the impact of key electronic parameters, such as the dynamic range, noise level, readout segmentation, and the FFT analysis of the waveform.
The final application of the $\mu$-RWELL detector is the muon system for the IDEA experiment proposed for FCC-ee. Optimizing the detector performance in conjunction with the electronics is a key task for the future experiment's design. The main challenge for the muon system is to ensure a good spatial resolution of the order of O(200 $\mu$m) and achieve high granularity to minimize the channel count.
