| MOPJE084 | Particle-in-cell Simulations of a Plasma Lens at Daresbury Laboratory | 518 |
|
||
| Feasibility of a focusing element using the transverse fields provided by a plasma cell was studied numerically. In this paper, an experimental set up is proposed for various beam parameters available from the VELA and CLARA beam lines at Daresbury Laboratory. 2D simulation results from VSim, and expected results from planned measurement stations are presented. Field properties and the advantages and disadvantages of such an instrument compared to conventional focusing elements are discussed. | ||

| TUPJE059 | Modeling of an Electron Injector for the AWAKE Project | 1762 |
|
||
|
Funding: Cockcroft Institute Core Grant Particle in cell simulations were performed to characterise an electron injector for AWAKE project in order to provide a tuneable electron beam within a range of specifications required by the plasma wakefield experiments. Tolerances and errors were investigated. These results are presented in this paper alongside with the investigation regarding the beam dynamics implications of the 3GHz travelling wave structure developed for the injector. |

| The interaction of the witness beam with the surrounding plasma particles and wakefields was studied. The implications of the elastic scattering process on beam emittance and, emittance evolution under the focusing and acceleration provided by plasma wakefields were discussed. Simulations results from GEANT4 are presented in this paper. | ||

| WEPWA048 | Design Studies and Commissioning Plans for PARS Experimental Program | 2612 |
|
||
|
Funding: Science and Technology Facilities Council and Cockcroft Institute Core Grant PARS (Plasma Acceleration Research Station) is an electron beam driven plasma wakefield acceleration test stand proposed for VELA/CLARA facility in Daresbury Laboratory. In order to optimise various operational configurations, 2D numerical studies were performed by using VSIM for a range of parameters such as bunch length, radius, plasma density and positioning of the bunches with respect to each other for the two-beam acceleration scheme. In this paper, some of these numerical studies and considered measurement methods are presented. |

| WEPWA049 | Low Energy Beam Tracking Under Scattering for a Cold Electron Source in Manchester | 2615 |
|
||
| High quality electron beams, with high spatial and temporal resolution, have an important use in electron diffraction experiments to probe and study the constituents of matter. A cold electron source is being developed based on electron ionisation from an atom cloud trapped by using AC magneto-optical methods in the University of Manchester. The technique will produce bunches of electrons well suited for high precision and single shot electron diffraction. In this paper issues of modelling at low energies for this state of art electron source with very low energy spread are presented, with a focus on newly developed tools to model the scattering in the meshes used to support the extraction electric fields. The dependence on emittance growth on mesh wire thickness is studied. | ||

| WEPWA051 | Investigations into Dielectric Laser-Driven Accelerators using the CST and VSIM Simulation Codes | 2618 |
|
||
|
Funding: European Union’s 7th Framework Programme for research, development and demonstration under grant agreement no 289191 and the STFC Cockcroft core grant No.ST/G008248/1. Dielectric laser-driven accelerators (DLAs) based on gratings structures confine the laser-induced accelerating field in a narrow vacuum channel where the electrons travel and are being accelerated. Recent proof-of-principle experiments have successfully demonstrated acceleration of electrons with accelerating gradients of up to 250 MV/m in such novel structures. This contribution presents detailed numerical studies into the acceleration of relativistic and non-relativistic electrons in double gratings silica structures. The optimization of these structures with regards to maximum acceleration efficiency for different spatial harmonics is discussed. Simulations were carried out using the commercial CST and VSIM simulation codes and results from both codes are shown in comparison. |

| THPF103 | Current Status of the SANAEM RFQ Accelerator Beamline | 3952 |
|
||
| The design and production of the proton beamline of SPP, which aims to educate accelerator physicists and serve as particle accelerator technologies test bench, continues at TAEK-SANAEM as a multi-phase project. For the first phase, the 20 keV protons will be accelerated to 1.3 MeV by a single piece RFQ. Currently, the beam current and stability tests are ongoing for the Inductively Coupled Plasma ion source and the measured magnetic field maps of the Low Energy Beam Transport solenoids are being matched to the RFQ acceptance with various beam configurations of the ion source by using computer simulations. The production of the RFQ cavity was started by using high grade aluminum material which will be subsequently coated by Copper to reduce the RF losses. The installation of the low energy diagnostics box was also completed. On the RF side, the development of the hybrid power supply based on solid state and tetrode amplifiers continues. All RF transmission components are already produced with the exception of the circulator and the power coupling antenna which are in the manufacture and design phases, respectively. The acceptance tests of the produced RF components are ongoing. This work summarizes the design, production and test phases of the above mentioned SPP proton beamline components. | ||
