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 next generation of lepton flavor violation experiments need high intensity and quality muon beams. Production such beams requires sending a short, proton pulse to the pion production target, capturing pions collecting resulting muons in large acceptance transport system. substantial increase beam can be obtained by applying RF phase rotation on dedicated FFAG ring, which was proposed for PRISM project.This allows reduce momentum spread purify from unwanted components like or secondary...
The main obstacle to the practical implementation of dielectric wakefield acceleration (DWA) concept is development beam breakup instability due transverse dipole wakefields generated when propagates off axis in accelerating structure. One methods suppress this elliptically shape and accelerate it a planar Here, we report detailed experimental investigation dynamics elliptical beams structure with parameters mimicking future DWA modules. Both quadrupole wakefields' effects on stability...
The ALICE tomography section at Daresbury is a diagnostic setup in the injection line of EMMA, world's first non-scaling FFAG accelerator. We present our measurements and analysis transverse emittance, Twiss parameters phase space distribution electron beam that injected into EMMA. are carried out 12 MeV, for bunch charges from 20 to 80 pC. Quadrupole scans used. results show charge effect does not change emittance significantly over length section. Starting projections images, quadrupole...
Daresbury Laboratory is currently building an Energy Recovery Linac Prototype (ERLP) that will operate at a beam energy of 35 MeV. In this paper we examine the space charge effects on dynamics in ERLP injector line. A Gaussian particle distribution tracked with GPT (General Particle Tracer) through injection line to main linac calculate effect 3D dipoles. The nominal 8.3 MeV and bunch 80 pC. transverse longitudinal emittance are studied for various electron parameter settings.
Orbital period in a ring accelerator and time of flight linear depend on the amplitude betatron oscillations. The variation is negligible ordinary particle accelerators with relatively small beam emittance. In an for large emittance beams like muons unstable nuclei, however, this effect cannot be ignored. We measured orbital non-scaling fixed-field alternating-gradient accelerator, which candidate muon acceleration, compared it theoretical prediction. good agreement between them gives...
Abstract Fringe fields at the entrances and exits of multipole magnets can adversely affect dynamics particles in an accelerator, but there is also possibility that fringe could be used to enhance accelerator performance. Design work benefit from computational tools for constructing realistic models early stage design process; methods relating magnet geometry field shape beam would significant value. We explore novel techniques produce designs satisfy specific requirements dynamics. Machine...
In high chromaticity circular accelerators, rapid decoherence of the betatron motion a particle beam can make measurement lattice and bunch values, such as Courant-Snyder parameters amplitude, difficult. A method for reconstructing momentum distribution from position measurements is presented. Further analysis same monitor data allows estimates to be made amplitude coherent oscillation beam. The methods are tested through application taken on linear nonscaling fixed field alternating...
Daresbury Laboratory is currently building an Energy Recovery Linac Prototype (ERLP) that will serve as a research and development facility for the study of beam dynamics accelerator technology important to design construction proposed 4th Generation Light Source (4GLS) project. Two major objectives ERLP are demonstration energy recovery from disrupted by FEL interaction supplied infrared oscillator system. In this paper we present start-to-end simulations including such interaction. The in...
The hourglass effect arises due to a coupling between the longitudinal and transverse bunch planes. This will result in charge density distribution that vary parabolically through Interaction Point (IP). Here method of analytically determining electric field particle receives from which varies when centred at IP, is derived for 2D model Gaussian bunch.
