“…Proton-proton collisions were simulated using the SIBYILL model in the Cosmic Ray Monte Carlo (CRMC) event generator [3]. Generated particles are propagated towards FASER using the Beam Delivery SIMulation (BDSIM) particle tracking code [4] capable of generating a Geant4 model [5] and tracking particles through an accelerator lattice and surrounding material. Particles reaching the FASER interface plane (IP, a virtual plane 1 m 2 in front of FASER detector) are passed to FASER detector software for reconstruction and analysis.…”

The ForwArd Search ExpeRiment (FASER) is a planned small-scale experiment designed for the search of light and weakly-interacting particles at the Large Hadron Collider (LHC). The FASER detector will be located along the beam collision axis, 480 m downstream from the ATLAS interaction point (IP), in an unused service tunnel. A full Geant4 model of the LHC accelerator as well as the surrounding tunnel complex has been developed to simulate the propagation of the products of the proton-proton collisions from the ATLAS IP to the FASER detector. The simulation also handles radiation from LHC beam induced background sources. The simulated fluences of Standard Model particles, which constitute the main signal and background of the experiment are presented.

“…The protons were propagated through the electron plasma using VSIM to simulate the impact of a number of plasma instabilities that have been observed experimentally [63,64]: a hollow electron ring and the diocotron instability [65]. The diocotron modes observed in the simulations corresponded to higher order modes with an azimuthal mode number m > 1.…”

An electron plasma lens is a cost-effective, compact, strong-focusing element that can ensure efficient capture of low-energy proton and ion beams from laser-driven sources. A Gabor lens prototype was built for high electron density operation at Imperial College London. The parameters of the stable operation regime of the lens and its performance during a beam test with 1.4 MeV protons are reported here. Narrow pencil beams were imaged on a scintillator screen 67 cm downstream of the lens. The lens converted the pencil beams into rings that show position-dependent shape and intensity modulation that are dependent on the settings of the lens. Characterisation of the focusing effect suggests that the plasma column exhibited an off-axis rotation similar to the m=1 diocotron instability. The association of the instability with the cause of the rings was investigated using particle tracking simulations.

“…Performance estimation was therefore performed using Monte Carlo particle-tracking from the ion source to the end station. BDSIM [81], which is based on the GEANT4 toolkit, was used for the simulation of energy deposition arising from beam interactions with the material in the accelerator and the end station. GPT [82] was used for evaluating the full 3D impact of space-charge effects.…”
