Terahertz (THz)-driven electron manipulation is a novel technique being explored with the goal of compact, efficient acceleration, compression, and deflection of electrons with tight-scale time control. In the Terahertz Acceleration Group, we have demonstrated significant advances in the field of novel electron manipulation methods, mainly using dielectric-lined waveguides (DLWs). We have...

The Zero Power Tuneable Optics (ZEPTO) project at STFC Daresbury Laboratory has developed several prototype permanent magnet quadrupoles with tuneable magnetic field gradient. These magnets have the largest tuning range so far demonstrated for permanent magnet quadrupoles, and operate by moving permanent magnet blocks relative to fixed steel structures that define the flux path, allowing...

Laser Wakefield Acceleration (LWFA) enables GV/m acceleration gradients, promising compact accelerator designs with advantages in cost, environmental impact and portability. Standard LWFA schemes can suffer from poor shot-to-shot stability and beam quality, resulting in broad energy spectrums, beam current variations, high emittance and limited intensity. External injection schemes attempt to...

Field emission or 'dark current' in the CLARA electron source(s) has been studied and monitored on the CLARA accelerator at Daresbury for its entire history. Dark current is an important topic in electron guns, usually for its potential negative consequences, and is the subject of study worldwide in many accelerators and gun development programmes at accelerator laboratories. We outline recent...

High performance electron accelerators require high brightness electron beams. To achieve this a photocathode with a high quantum efficiency (QE) and low intrinsic emittance is required while also being robust with a long lifetime and low dark current. Photocathodes based on alkali metals can fulfil these requirements and, as such, are an important area of research for the accelerator physics...

FLASH Radiotherapy is an emerging novel type of radiotherapy where dose rates of higher than 40Gy/s are used compared to conventional radiotherapy where less than 1Gy/s are used. This study will consider the usage of Photons to achieve the FLASH effect. Whilst not understood, dose rates of this magnitude harm healthy tissues less than that of tumours. There is currently a lack of research into...

ISIS is a pulsed neutron and muon source at the Rutherford Appleton Laboratory in the UK. The accelerator complex consists of a 70 MeV H(-) linac and an 800 MeV proton Rapid Cycling Synchrotron (RCS), which delivers beams of up to 3e13 protons to its fixed targets. A 50 kV electrostatic beam chopper is installed in the High Energy Drift Space (HEDS) which connects the linac to the RCS for...

Laser wakefield acceleration (LWFA) can generate accelerating fields of several hundred GV/m, offering a promising route towards compact and cost-effective accelerator systems. Carbon nanotube (CNT) bundle-based targets have attracted increasing interest as solid-state plasma sources because of their high plasma density (>10$^{19}$ cm$^{-3}$), tunable effective density, excellent thermal...

Modern particle accelerators have been used in a wide range of fields, including scientific research and medical applications that demand a high-quality particle beam. To achieve an excellent beam standard for these applications, an accelerator requires reliable and accurate diagnostic instruments capable of measuring the phase space distribution of the beam in complex experiments. Tomography...

Reliable access to radiotherapy remains unsatisfactory in many Lower- and Middle-Income Countries (LMICs) to date, where a lack of Linear Accelerators (LINACs) and consistent machinery failures cause delayed treatment. In some cases, machine downtime can leave patients without care for extended periods of time. Previous studies identified the Multileaf Collimator (MLC) as an under-studied...

It is known that the addition of a static magnetic field has a degrading effect on the performance of RF cavities, a situation presenting particular problems for the cooling channel of a muon collider. Within this environment, a strong external magnetic field (2–5 T) is superimposed upon the RF field in order to provide beam focusing. The RF field for such systems is required to be in the...

Terahertz (THz) driven dielectric lined waveguides (DLW) have recently been demonstrated to provide relativistic acceleration, femtosecond control of electron beams and longitudinal beam diagnostics via THz-driven streaking. [1] But to achieve optimal efficiency, these structures need narrowband sources at a target frequency and precise timing with high THz pulse energies (on the order of...

In this work, we assess the performance and limitations of Mach-Zehnder interferometry for plasma diagnostics using a fully synthetic, numerically generated dataset. We explore regions of parameter space that are difficult to access experimentally, including fringe behaviour, the dynamic range of measurable phase shifts, and the resolution limits for low-density plasmas. By introducing...

CLARA is a 250 MeV linear electron accelerator which operates as a test facility for particle accelerator techniques and technology. As a photoinjector machine the properties of the electron beam initially depend heavily on the properties of the incident laser pulse, and the need for a source of high brightness and reliable electron bunches with flexible parameters put strenuous requirements...

There is a growing demand for generating and transporting ultrashort, high-charge-density relativistic electron bunches for applications ranging from free-electron lasers to future high-energy colliders. Laser-plasma wakefield accelerators (LWFAs) offer a promising route towards compact high-gradient acceleration; however, electron bunches generated through plasma self-injection often suffer...

Dielectric-lined waveguides (DLWs) can support hybrid modes with strong accelerating longitudinal and transverse focusing electric-field components. By precisely tailoring the waveguide geometry, the electromagnetic field profile, phase velocity, and group velocity can be tuned to maintain synchronisation between relativistic bunches and the accelerating mode over extended distances. When...
