Full Job Description
Gaseous particle detectors are essential in particle physics and radiation detection, encompassing technologies such as Micro-Pattern Gaseous Detectors (MPGDs), straw and drift tubes, Resistive Plate Chambers (RPCs), drift chambers, and Time Projection Chambers (TPCs). These detectors - all under consideration for future experiments - differ in their underlying detector physics, readout, and specifications, yet all benefit from predictive modelling and simulation to guide design, gas choice, performance optimisation, and operation. The EP-RD group has consolidated extensive expertise in this field, establishing frameworks that link microscopic processes — including electron transport, gas amplification and signal induction — with macroscopic detector response. Building on this foundation, the fellowship will focus on two complementary objectives: development/support of modelling and simulation tools, and gas mixture optimisation and identification. Your responsibilities * Support the development and maintenance of the Garfield++ modelling and simulation framework for gaseous detectors, including the integration of novel technological approaches. * Develop and improve methodologies and software tools for the selection, characterisation, and optimisation of detector gas mixtures. This includes identifying key measurements and performance indicators, predicting trends linking medium properties to detector behaviour, and supporting experimental validation through available data and dedicated measurements. * Maintain active liaison and collaboration with modelling and simulation developers working on detector technologies relevant to CERN. * Coordinate community efforts within the DRD1 Collaboration framework towards common objectives relevant to CERN detector R&D activities. * Support a deeper understanding of detector mechanisms and providing essential guidance for detector optimisation and performance improvement. * Upgrade simulation tools to address current challeng
