  Due to the large stored beam energy in the HL-LHC new collimation technologies must be used to protect the machine. Active halo control of the proton beam halo with a Hollow Electron Lens can give a kick to protons at the edge of the beam without effecting the core. Various modes of operation are possible for example the electron lens can have a continuous current or it can be pulsed to different amplitudes for each passage of the proton beam. In this article we use Merlin++ simulations to show the performance of these modes for HL-LHC parameters. We also present recent simulations comparing scattering models in Merlin++.

  Precise neutrino cross section measurements and search for sterile neutrinos can be done with neutrino beams produced from muons decaying in a storage ring due to its precisely known flavour content and spectrum. In the proposed nuSTORM facility pions would be directly injected into a racetrack storage ring, where circulating muon beam would be captured. The storage ring has three options: a FODO solution with large aperture quadrupoles, a racetrack FFA (Fixed Field Alternating gradient) using the recent developments in FFAs and a hybrid solution of the two previous options. Machine parameters, linear optics design and beam dynamics of the hybrid solution are discussed in this paper.

The Large Hadron Collider (LHC) has attracted significant attention from the general public. The science of the LHC and Higgs Boson is primarily communicated to school children and the wider public using visual methods. As a result, people with visual impairment (VI) often have difficulty accessing scientific communications and may be culturally excluded from news of scientific progress. Tactile Collider is a multi-sensory experience that aims to communicate particle accelerator science in a way that is inclusive of audiences with VI. These experiences are delivered as a 2-hour event that has been touring the UK since 2017. In this article we present the methods and training that have been used in implementing Tactile Collider as a model for engaging children and adults with science. The event has been developed alongside experts that specialise in making learning accessible to people with VI.
