Bent silicon crystals have been integrated into the Large Hadron Collider (LHC) as part of the collimation system. More are planned to be installed this year for a fixed-target experiment. I present a summary of recent measurements with LHC crystals using CERN facilities, and introduce the future experiments TWOCRYST and ALADDIN.
In AWAKE, the Advanced WAKefield Experiment, relativistic proton bunches produced by the CERN Super Proton Synchrotron (SPS) are used to drive high gradient plasma wakefields for the acceleration of short-pulse electron bunches to 2 GeV in a 10 m plasma cell. Precise control of the injected electrons is vital for operation of the seeding of the self modulation of the proton bunch, therefore...
3D imaging is a key diagnosis tool within medical contexts. This is particularly important in applications such as chest scans, where the symptoms of interest, such as pulmonary nodules, may be obscured by layers of tissue and other overlapping biological structures. The higher image resolution required to make the structures of interest identifiable in this context creates the demand for...
At NNL we have a developed a new tool, the Computational Assessment of Radionuclide Production tool, or CARP for short, which models the evolution of a target material's nuclide inventory when irradiated by an incident particle beam. The intention of the tool is to allow quick assessments of radionuclide production, highlighting the yield of any nuclides of interest and the downfalls of the...
We present a laser-assisted electron injection scheme for beam-driven plasma wakefield acceleration. The laser is colinear with the driver and triggers the injection of hot electrons into the plasma wake by interaction with a thin solid target. We explore the scheme through numerical simulations, using the AWAKE Run 2 parameters as a baseline. The final beam quality is better than similar...
Interaction between laser-generated terahertz (THz) radiation and high-energy electron beams has become a research topic of interest, owing to the higher field gradients available compared to conventional radio-frequency (RF) accelerators, and the utility of mm-scale wavelengths for sub-ps bunch manipulation and diagnostics. We have shown that multi-cycle THz energy modulation of relativistic...
Ballistic damage due to scattering plays a key role in the degradation of nuclear materials. Due to the challenge of low flux, material activation and irrelevant beam spectra, researchers into fusion materials often rely on simulating ballistic damage through ion implantation. In this work, heavy ion implantation has been carried out in HZDR using a Ti ion beam at 500 °C and a fluence of...
