Model of Electron Output Non-linearity 20m
The CYGNO collaboration is developing a gaseous time projection chamber
with optical readout of a triple-GEM stack for directional dark matter
searches. While this technique provides detailed reconstruction of event
topology, it requires operation at high gain of the amplification stage,
where nonlinearities in the GEM response become significant. We present
a model developed to describe these nonlinear effects and compare the
simulated results with experimental dataSpeaker: Davide Pinci (INFN - Roma) -
11:20
Use of Oxygen in Drift Chamber: comparison with Garfield (remote) 20m
We examined the algorithm used in Garfield++ for computing the electron attachment in gaseous mixtures
and we found that it can be corrected by hand to take into account the contributions of individual gases to
the attachment mechanism. We applied the revised calculation to compute the electron attachment as a
function of the electric field and compared the results with some experimental results, obtaining reasonable
agreement for mixtures containing noble gases, isobutane and oxygen.Speaker: Fabrizio Cei -
11:40
The modeling of rate effects in RPCs 20m
Abstract:This work introduces Markov modelling to describe how resistive plate chambers (RPC) deteriorate under uniform background irradiation. The model works for high irradiation rates and arbitrary charge spectra. Applied to M. Abbrescia’s single-cell RPC model (RC circuit), it agrees with Monte Carlo simulations and can also describe RPCs with polarizable resistive layers and in two dimensions. Including streamer-like events (large charge) allows the model to match experimental efficiency curves, showing that these events cause the reduction of the efficiency plateau at high irradiation rates. For eco-friendly gas mixtures, this means suppressing streamers is key for reaching high-rate capability.
