New acceleration technology is mandatory for the future elucidation of fundamental particles and their interactions. A promising approach to exploit properties plasmas. Past research has focused on creating large-amplitude plasma waves by injecting an intense laser pulse or electron bunch into plasma. However, maximum energy gain electrons accelerated in a single stage limited driver. Proton bunches are most drivers wakefields accelerate TeV scale stage. An experimental program at CERN—the...
Understanding the influence of exposure biological systems to THz radiation is becoming increasingly important. There some evidence suggest that can important activities within mammalian cells. This study evaluated high peak power, low average power produced by ALICE (Daresbury Laboratory, UK) synchrotron source on human epithelial and embryonic stem The cells were maintained under standard tissue culture conditions, during which was delivered directly into incubator for various times. cell...
This report describes the conceptual design of a proposed free electron laser test facility called CLARA that will be major upgrade to existing VELA accelerator at Daresbury Laboratory in UK. able number new schemes have been but require proof principle experiment confirm they perform as predicted. The primary focus on ultra short photon pulse generation which take lasers into whole regime, enabling area science emerge.
The compact linear accelerator for research and applications (CLARA) is an ultrabright electron beam test facility being developed at STFC Daresbury Laboratory. ultimate aim of CLARA to advanced free laser (FEL) schemes that can later be implemented on existing future short-wavelength FELs. In addition, a unique provide high-quality novel concepts ideas in wide range disciplines function as technology demonstrator United Kingdom x-ray FEL facility. built three phases; the first phase, or...
We propose a Plasma Accelerator Research Station (PARS) based at proposed FEL test facility CLARA (Compact Linear for and Applications) Daresbury Laboratory. The idea is to use the relativistic electron beam from CLARA, investigate some key issues in transport driven plasma wakefield acceleration, e.g. high gradient excitation by bunch, two bunch experiment energy doubling, transformer ratio, long self-modulation other advanced dynamics issues. This paper presents feasibility studies of meet...
The Versatile Electron Linear Accelerator (VELA) facility will provide enabling infrastructures targeted at the development and testing of novel compact accelerator technologies, specifically through partnership with industry aimed addressing applications in medicine, health, security, energy industrial processing. has now been commissioned Daresbury Laboratory is being actively utilised by groups who are able to take advantage variable electron beam parameters available on VELA either...
A user facility VELA (Versatile Electron Linear Accelerator) based on an RF photoinjector has been commissioned at Daresbury Laboratory in April 2013, providing beam to first users September 2013. Machine study runs 2013-2014 have concentrated characterisation of main parameters like bunch charge, its momentum, emittance and dependence these the launching phase. Major efforts also investigation dark current from gun amplitude. Significant time dedicated relative stability LLRF drive laser...
An rf pulse propagating through a travelling wave linac can be seen to evolve due dispersion. To accurately predict the field amplitude experienced by electron bunches cavity, this evolution must well known. Here we present an method using Fourier methods. The requires two inputs calculate dispersion: group velocity as function of cell number, and phase advance. Attenuation is included in model with addition third input: cavity Q0. faster more simple than 3D modelling, allows subtle details...
Accelerator drivers for Energy Recovery Linac (ERL) and Free-Electron Laser (FEL) based light sources demand electron injectors which deliver high brightness bunches on the several hundreds of picocoulomb scale, at repetition rates between 1 MHz GHz (or higher), corresponding to an average current 0.1 100 mA. Simultaneous satisfaction these injector requirements is considerably beyond state-of-the-art. Daresbury Laboratory concentrating efforts development III-V XnY3−nSb photocathode-based...
The ALICE accelerator (Accelerators and Lasers In Combined Experiments) at Daresbury Laboratory is a 35 MeV ERL. electron beam drives an infra-red free-electron laser (FEL) THz light sources, but can also be used to generate X-rays through Compton back-scattering (CBS). acts as the injector for EMMA NS-FFAG machine. This paper will outline project status milestones achieved thus far, focussing on performance of photoinjector gun injection line.
Accelerator based Ultrafast Electron Diffraction (UED) is a technique for static and dynamic structural studies in material biological sciences. The recently commissioned VELA accelerator at the Daresbury Laboratory provides multi-MeV beams science industry will provide test bed UK electron diffraction community. We present design of diffractometer currently being installed on which allow capture single shot pattern with 1 pC bunch outline future options.
As part of the design CLARA (Compact Linear Accelerator for Research and Applications), proposed UK FEL test facility at Daresbury Laboratory, a high repetition rate S-band photoinjector RF gun is being developed. This will be able to operate up 400 Hz in single bunch mode. We present initial cavity design, including its optimisation beam dynamics CLARA. also cooling which enable rates achieved.
