Simulating and measuring radiation backgrounds at LHC experiments

Ian Dawson

University of Sheffield (UK)

Abstract: Modern high energy collider experiments are designed to operate in harsh radiation environments. Simulation is crucial for understanding and providing information about the complex radiation backgrounds, and this is vital input in the choice and design (and therefore cost) of detector systems. In this seminar I will first discuss how the LHC radiation fields are simulated to produce particle fluence and ionising dose estimates, and show how this information is used to predict radiation damage in silicon sensors and electronics. I will also describe how since 2010 the measured responses of ATLAS detector systems, as well as dedicated radiation devices, have been used to validate the radiation background simulations, and explain why this is important for future upgrades. Finally, the same simulation framework is used for estimating the residual dose rates to personnel from activation, an understanding of which is crucial for planning access for maintenance and decommissioning scenarios. 

Seminar takes place on Tuesday, September 12th 2017 at 2:00 PM
in the IEAP meeting room, Praha 2 ‐ Albertov, Horská 3a/22.
