/ D'Alessandro, Gian Luigi (CERN ; JAI, UK) ; Banerjee, Dipanwita (CERN) ; Bernhard, Johannes (CERN) ; Boogert, Stewart T (JAI, UK) ; Brugger, Markus (CERN) ; Doble, Niels (CERN ; Mainz U.) ; Gatignon, Laurent (CERN ; Lancaster U.) ; Gerbershagen, Alexander (CERN) ; Gibson, Stephen M (JAI, UK) ; Marchevski, Radoslav (CERN ; Mainz U.) et al.
The NA62 experiment is a fixed target experiment located in the North Area of CERN and has as main goal the measurement of the branching ratio of the rare decay K±>pi+vv. The primary proton beam from the SPS accelerator interacts with the T10 beryllium target and the generated 75 GeV/c secondary particles, containing about 6% of positive kaons, are transported by the K12 beamline to the NA62 experiment.

CERN has a unique set of secondary beam lines, which deliver particle beams extracted from the PS and SPS accelerators after their interaction with a target, reaching energies up to 400 GeV. These beam lines provide a crucial contribution for test beam facilities and host several fixed target experiments. [...]

Recent BDSIM Related Developments and Modeling of Accelerators
/ Nevay, Laurence J (JAI, UK) ; Abramov, Andrey (CERN) ; Alden, Siobhan E (JAI, UK) ; Boogert, Stewart T (JAI, UK) ; D'Alessandro, Gian Luigi (JAI, UK) ; Gibson, Stephen M (JAI, UK) ; Gnacadja, Eustache (Brussels U.) ; Hernalsteens, Cédric (CERN) ; Lefebvre, Helena (JAI, UK) ; Liu, Shan L (DESY) et al.
Beam Delivery Simulation (BDSIM) is a program based on Geant4 that creates 3D radiation transport models of accelerators from a simple optical description in a vastly reduced time frame with great flexibility. It also uses ROOT and CLHEP to create a single simulation model that can accurately track all particle species in an accelerator to predict and understand beam losses, secondary radiation, dosimetric quantities and their origin.

Muon background minimisation using the second achromat of the NA62-BD experiment

The K12 beam line and NA62 experiment in the North Area at CERN in beam dump mode exploits the interactions of 400 GeV protons with a movable dump-collimator, the so-called XTAX. Such interactions are theorised to generate potential light dark matter candidates such as the axion. [...]

First Studies of Ion Collimation for the LHC Using BDSIM

At the Large Hadron Collider (LHC) at CERN ion physics runs are performed in addition to proton physics runs. In ion operation the cleaning efficiency of the collimation system is lower than in the case of protons and the ion showering process is more complicated and produces a larger variety of secondary particles.

The Physics Beyond Colliders initiative aims to exploit the full scientific potential of the CERN accelerator complex and its scientific infrastructure for particle physics studies, complementary to current and future collider experiments. Several experiments have been proposed to fully utilize and further advance the beam options for the existing fixed target experiments present in the North and East Experimental Areas of the CERN SPS and PS accelerators.

Investigation of CLIC 380 GeV post-collision line
/ Bodenstein, Ryan (JAI, UK ; Oxford U. ; CERN) ; Abramov, Andrey (JAI, UK ; Royal Holloway, U. of London ; CERN) ; Boogert, Stewart (JAI, UK ; Royal Holloway, U. of London) ; Burrows, Philip (JAI, UK ; Oxford U. ; CERN) ; Nevay, Laurence (JAI, UK ; Royal Holloway, U. of London ; CERN) ; Schulte, Daniel (CERN) ; Tomás, Rogelio (CERN)
It has been proposed that the Compact Linear Collider (CLIC) be commissioned in stages, starting with a lower-energy, 380 GeV version for the first stage, and concluding with a 3 TeV version for the final stage. In the Conceptual Design Report (CDR) [1] published in 2012, the post-collision line is described for the 3 TeV and 500 GeV stages. [...]

The P42 beamline transports 400 GeV protons from the CERN SPS between the T4 and T10 targets. A secondary particle beam is produced at the T10 target and transported along the K12 beamline to the experimental cavern ECN3, presently housing the NA62 experiment. [...]

The K12 beamline for the KLEVER experiment

The KLEVER experiment is proposed to run in the CERN ECN3 underground cavern from 2026 onward. The goal of the experiment is to measure ${\rm{BR}}(K_L \rightarrow \pi^0v\bar{v})$, which could yield information about potential new physics, by itself and in combination with the measurement of ${\rm{BR}}(K^+ \rightarrow \pi^+v\bar{v})$ of NA62.
