RADIATION BACKGROUND STUDIES
- Introduction
Already at the LHC the high levels of radiation background will be unprecedented and this has had a major impact on the design of the machine and experiments. At the SLHC the situation will be even more challenging. The backgrounds will degrade detector and trigger performance, cause detector and electronics damage, induce digital upsets that can corrupt data, and give rise to radioactivation of the experiment that will severely impact detector access and maintenance scenarios. Given the significant resource implications of upgrading ATLAS for operation at the SLHC, it is crucial that any radiation background issues are addressed as early as possible. Two broad areas of R&D can be identified. First, measurements of particle fluences at LHC luminosities should be obtained to allow benchmarking of the Monte Carlos particle transport codes. Given the reliance on these codes for large scale projects such as ATLAS, as well as future High Energy Physics projects at the SLHC or CLIC/TESLA, then the motivation for their benchmarking is obvious. Secondly, a program of simulations for the ATLAS upgrade can be defined using the existing versions of the particle transport codes.
This work is carried out by Dr. Ian Dawson and Dr. Paul S. Miyagawa, funded mainly through the STFC.
