Plasma-wakefield acceleration offers a promising alternative to radio-frequency technology for future accelerators due to the very high accelerating gradients (>GV/m) it can sustain. However, key challenges remain before meaningful application can begin, for example the staging of multiple plasma modules (to achieve very high beam energy) and achieving MHz-GHz repetition rates (to achieve very...

Understanding femtosecond longitudinal electron bunch properties including the temporal profile and slice parameters, together with the synchronisation to an external laser system is of key importance for accelerators operating with ultrashort bunches, such as UED machines, FELs, LWFAs. A well-established route to measuring these properties is to use radio-frequency transverse-deflecting...

With improvements in RF technology, as well as potential novel THz or plasma-based acceleration mechanisms, particle bunches have the potential to be compressed down to the 10 fs scale and below. To complement these advances and allow exploitation of these ultrashort beams, more precise longitudinal beam diagnostics are required.
Well-established electro-optic (EO) techniques offer...

We introduce a novel scheme for the simulation of plasmas and accelerator beams: the moment-based particle-in-cell (PIC) code. This scheme is similar to a standard PIC code, with the key distinction being that the simulation objects have a dynamic shape. These simulation objects, called super-macroparticles (SMPs), are assigned a phase-space distribution at runtime, the dynamics of which are...

The Future Circular Electron-Positron Collider (FCCee) requires calibration of the collision energy to within an error of a few 10 keV. This high precision can be reached via Resonant Depolarisation (RDP), which requires a precise and consistent measurement of the polarisation of pilot bunches in the collider ring. The design of an inverse Compton polarimeter is presented, along with the...

Bhabha scattered electrons are used to measure relative luminosity away from the IP. At SuperKEKB, this has been demonstrated using CVD diamond detectors at 4m from the IP. LGADs (Low Gain Avalanche Diode) have recently been tested as a potential alternative with the Lumibelle2 collaboration. This sensor has a much faster rise time, on the order of a nanosecond, but may be more susceptible to...

The Electron-Ion Collider (EIC) is a high-current, high luminosity (10^34 cm^2 s^(-1)) machine designed to reveal the internal spin structure of the proton by colliding beams of electrons and heavy ions such as lead and uranium. Frequent small angle Coulomb scattering, known as intra-beam scattering of the ion beam causes emittance growth, degrading luminosity. Coherent electron cooling is...

The Ghost Collider (GC) is an innovative proposal for a 550 GeV centre-of-mass (275 GeV per beam) linear collider with four interaction regions arranged in series, each with the design luminosity. The primary innovation is the use of “ghost bunches” containing equal numbers of electrons and positrons, thereby net electrically neutral. In the linacs, energy is transferred between electrons and...

With cancer rates increasing, the need for effective treatments is urgent. Very High Energy Electron (VHEE) and FLASH therapies could revolutionise cancer treatment, offering effective cancer cell killing while reducing induced side effects and reducing treatment delivery time. CLARA beamline upgrades make VHEE beam production at conventional (CONV) and ultra-high dose rates (UHDR) possible...

Here we present a conspectus of very high energy electron (VHEE) developments and the potential for FLASH radiotherapy across multiple accelerator facilities. FLASH radiotherapy (FLASH-RT) delivers radiation at ultra-high dose rates (>40 Gy/s) and has demonstrated the potential to reduce normal tissue toxicity while maintaining tumour control compared with conventional dose-rate irradiation....

LhARA is a multidisciplinary collaboration that aims to use laser-driven ions in a hybrid acceleration scheme with an FFA both to deliver a systematic radiation biology programme and to lay the technological foundations for the transformation of proton and ion beam therapy. The UKRI Infrastructure Fund ‘Ion Therapy Research Facility’ Preliminary Activity supported the preparation of a...

Ion beams with energy up to a few MeV have been widely produced and used at Surrey Ion Beam Centre for various applications. Now we have five tools available for ion beam modification of materials, and one more new tool is under development for ion beam deposition. Examples of applications are: the manipulation of electrical conductivity; the investigation of irradiation induced stress and...

The Hybrid Electromagnet-Permanent Magnet Tuneable Optics (HEPTO) magnet has been designed and built as part of the I.FAST collaboration as an energy saving alternative to traditional resistive electromagnets. The prototype magnet has been designed to meet the magnetic field requirements of the combined function dipole-quadrupole (DQ) magnets required for the Diamond-II upgrade. The prototype...

X-ray based Cargo and Vehicle Inspection (CVI) systems are used for security and customs inspection applications. CVI systems primarily require compact and reliable linear accelerators for Bremsstrahlung-based X-ray transmission imaging of threats and contraband. X-ray imaging quality of CVI systems is impacted by the beam dynamics of linear accelerators.
Therefore, the Rapiscan Linac Test...

Superconducting radio frequency (SRF) cavities underpin many modern particle accelerators, enabling highly efficient acceleration with high duty cycle or continuous wave operation. However, SRF technology currently relies almost exclusively on bulk niobium cavities operating at around 2 K, resulting in significant capital and operational costs while performance approaches the theoretical...
