Abstract

CERN has a unique set of secondary beam lines, which deliver particles extracted from the PS and SPS accelerators after their interaction with a target material reaching energies up to 400 GeV. These beam lines provide a crucial contribution for test beam facilities, and host several fixed target experiments. A correct operation of the beam lines requires precise simulations of the beam optics and studies on the beam-matter interaction, radiation protection, beam equipment survival etc. BDSIM combines tracking studies with energy deposition and beam-matter interaction simulations within one software framework. This paper presents studies conducted on secondary beam lines with BDSIM for the beam lines T9 and T10. We report the tracking analysis and the energy deposition along the beam line. Tracking analysis validation is demonstrated via comparison to existing tracking codes.

Summary

INTRODUCTION

Beam Delivery Simulation (BDSIM) [1] is an open source software developed at Royal Holloway, University of London It is a C++ program that utilises the Geant toolkit to simulate both the transport of particles in an accelerator and their interaction with the material. Secondary beam lines at CERN are utilised as a facility for test beams and fixed target physics experiment. This paper presents studies on secondary beam lines simulated with this software. The secondary beam lines subject to these studies are T9 and T10 located in the East Area on the Meyrin site of CERN, see Figure 1. 3. OPTICS In the past, three software codes were used for the East Area secondary beam lines studies, TRANSPORT, TURTLE and BEATCH [4][5][6]. At this point a comparison between MADX and BDSIM is possible
