PIER Workshop on Non-Sensitive Materials in High Energy Physics

One of the challenges of future high-energy physics experiments at the high-luminosity LHC and the future Linear Collider is to reduce the passive material in the sensitive volume of the inner tracking detectors while increasing the granularity and complexity of the detector systems in order to cope with the increased occupancy. Moreover, the upgraded high-luminosity LHC trackers will have to be cooled to a temperature of below -20°C in order to allow for an operation in the harsh radiation environment. For both, the future CMS tracker modules and the ATLAS Silicon Strip Upgrade, the requirements of mechanical stability, heat transport and material reduction leads to multi-layer sandwich constructions of various materials with different properties. While cooling and power consumption are not the main issue for the Linear Collider, the material budget is ultimately the limiting factor for the physics performance. Therefore ultra-light detector structures are mandatory.
This workshop with participants from industry and academia will review the requirements and collect the needs of the particle physics community as well as collect information from industrial companies on high-tech materials with specific thermal and mechanical properties. It will open possibilities of in-depth discussion in order to understand options and limitations and, ideally, to open up new possibilities for collaborations and solutions.
