OuroborosBEM: Simulation of space-charge effects in gazeous detectors using GPUs, and more…

Samuel Salvador (LPC Caen, France)

When it comes to simulating the behaviour of gaseous detectors, not many tools are available on the market. In the scientific community, an open-source software created by a CERN member is used for years, Garfield++, but has many flaws concerning up-to-date simulations of specific detectors. In fact, the microscopic simulation process is very slow, it cannot be used to generate complex electric fields and does not include any space-charge effects. Those space-charge effects are of importance when looking for instance into the details of a large avalanche in a Gaseous Electron Multiplier (GEM) detector or in the case of high intensity beams. OuroborosBEM has been developed to overcome all those issues at once. For that, it is based on the CUDA programming language for nVidia Graphic Processor Units (GPU) to speed-up all the processes. The tremendous computational power of those made it possible to include the possibility to process electric fields from complex geometries (with electrodes and dielectric materials) and even include the space-charge effects at the microscopic level.
