ColMat BDSIM – LHC

This document provides an overview of the current progress, plans, and people involved in the BDSIM project for simulating and tracking the LHC beamline. It discusses the interface with MAD decks, GMAD, energy losses, radiation conditions, shielding, interaction regions, geometry modeling, and more. The document also highlights the current status, upcoming simulations, and future interfaces with ATLAS and other components.

  1. G A Blair, L.C Deacon ColMat Kickoff Meeting 17th June 2009 ColMatBDSIM – LHC • People • BDSIM • Plans

  2. People Grahame Blair Lawrence Deacon Currently working on BDSIM for LHC: Previous contributors/future collaborators? • Ilya Agapov • John Carter • Steve Malton • Andrea Latina 2

  3. BDSIM Builds beamline readily from MAD deck; needs a script to convert from MAD8 format. GMAD interface for defining geometries and fields Full simulation and tracking of secondaries Mapping of energy losses Sampling of particle distributions Accelerator tracking incorporated in Geant4: NIM A 10.1016/j.nima.2009.04.040 3

  4. Losses in ILC extraction line 100W/m hands-on limit 20mrad 20mr: losses < 100W/m at 500GeV CM and 1TeV CM2mr: losses are at 100W/m level for 500GeV CM and exceed this level at 1TeVRadiation conditions and shielding to be studied Losses are mostly due to SR. Beam loss is very small 2mrad 250GeV Nominal, 0nm offset 100W/m 45.8kW integr. loss Losses are due to SR and beam loss J. Carter, I. Agapov, G.A. Blair, L. Deacon (JAI/RHUL), A.I. Drozhdin, N.V. Mokhov (Fermilab), Y.M. Nosochkov, A.A. Seryi (SLAC) J. Carter

  5. Interaction Region in BDSIM • Full IR Geometry modelled in BDSIM • Using MySQL geometry database • Includes a full Solenoid Field Map Choose from TESLA, GLD, or SiD fields Will interface to detector concepts. Leading role in MDI Z Component Radial Component at 1m from beamline Screenshot of an IR Design in BDSIM J. Carter

  6. LHC Beam line layout in BDSIM Dipole magnet Final 60m (minus final drift) before ATLAS IP n-poles collimators quads L. Deacon

  7. Current Status MAD deck updated to enable LHC beamline builds. BDSIM creates last 60m of beamline before ATLAS. Can go back as far as necessary. Chiara Bracco has sent us collimator particle hits, which we can use as input to BDSIM full tracking. We plan first runs this week and present next week at CERN. Develop interface to ATLAS full simulation and beampipe upgrades. 7

  8. Summary • BDSIM is ideal for full simulation of LHC beamline including full secondary production and tracking • Interfaces to Sixtrak output have been defined • First simulations are now underway • ATLAS interfaces planned • Well defined programme; we’re ready to go…
