TUPRB032 | The CompactLight Design Study Project | 1756 |
|
||
Funding: This project has received funding from the European Union’s Horizon2020 research and innovation programme under grant agreement No 777431 The H2020 CompactLight Project (www. CompactLight.eu) aims at designing the next generation of compact X-rays Free-Electron Lasers, relying on very high gradient accelerating structures (X-band, 12 GHz), the most advanced concepts for bright electron photo injectors, and innovative compact short-period undulators. Compared to existing facilities, the proposed facility will benefit from a lower electron beam energy, due to the enhanced undulators performance, and will be significantly more compact, with a smaller footprint, as a consequence of the lower energy and the high-gradient X-band structures. In addition, the whole infrastructure will also have a lower electrical power demand as well as lower construction and running costs. |

TUPTS024 | Design of a Full C-Band Injector for Ultra-High Brightness Electron Beam | 1979 |
|
||
High gradient rf photo-injectors have been a key development to enable several applications of high quality electron beams. They allow the generation of beams with very high peak current and low transverse emittance, satisfying the tight demands for free-electron lasers, energy recovery linacs, Compton/Thomson sources and high-energy linear colliders. In the paper we present the design of a new full C-band RF photo-injector recently developed in the framework of the XLS-Compact Light design study and of the EuPRAXIA@SPARC_LAB proposal. It allows to reach extremely good beam performances in terms of beam emittance (at the level of few hundreds nm), energy spread and peak current. The photo-injector is based on a very high gradient (>200 MV/m) ultra-fast (RF pulses <200 ns) C-band RF gun, followed by two C band TW structures. Different types of couplers for the 1.6 cell RF gun have been considered and also a new compact low pulsed heating coupler working on the TM020 mode on the full cell has been proposed. In the paper we report the design criteria of the gun, the powering system, and the results of the beam dynamics simulations. We also discuss the case of 1 kHz repetition rate. | ||

WEZPLM1 | The LATINO Project - An Italian Perspective on Connecting SMEs with Research Infrastructures | 2277 |
|
||
Funding: The LATINO project is co-funded by the Regione Lazio within POR-FESR 2014-2020 European activities (public call ’Open Research Infrastructures’). The National Laboratories of Frascati (LNF) are the first Italian research facility for the study of nuclear and subnuclear physics with accelerators and are the largest laboratories of the Italian National Institute for Nuclear Physics (INFN), the public body whose mission is theoretical, experimental and technological research in subnuclear, nuclear and astroparticle physics. LNF have an extensive experience in designing, installation, testing and operation of particle accelerators and the related technologies. The competences range over almost all the technologies related to particle accelerators, including radio frequency, vacuum, magnets and mechanics. LNF have always had a close relationship with the regional and national industries, stimulating the development and growth of the industrial background by means of close collaboration with partners. The LATINO (a Laboratory in Advanced Technologies for INnOvation) project is an initiative that fits into this path and aims to strengthen this relationship, allowing access to the technologies, instruments and competences not otherwise available to the enterprises. A modern vision of advanced economies recommends the Technology Transfer from the research world to the productive activities through the creation of research infrastructures as the most efficient system for generating innovation and economic development [1-3]. The Regione Lazio, despite hosting centres of excellence, has a delay in the establishment of this kind of infrastructures. |

WEZZPLS2 | EuPRAXIA, a Step Toward a Plasma-Wakefield Based Accelerator With High Beam Quality | 2291 |
|
||
Funding: European Union’s Horizon 2020 research and innovation programme under grant agreement No. 653782 The EuPRAXIA project aims at designing the world’s first accelerator based on plasma-wakefield advanced technique, which can deliver a 5 GeV electron beam with simultaneously high charge, low emittance and low energy spread to user’s communities. Such challenging objectives can only have a chance to be achieved when particular efforts are dedicated to identify the subsequent issues and to find the way to solve them. Many injection/acceleration schemes and techniques have been explored by means of thorough simulations in more than ten European institutes to sort out the most appropriate ones. The specific issues of high charge, high beam quality and beam extraction then transfer to the user’s applications, have been tackled with many innovative approaches*. This article highlights the different advanced methods that have been employed by the EuPRAXIA collaboration and the preliminary results obtained. The needs in terms of laser and plasma parameters for such an accelerator are also summarized. *- in 2017: Phys. Plasmas, 24,10,103120; Nat.

WEPGW022 | A Numerical Analysis to Choose the Most Performing Optical Transition Radiation Screen | 2518 |
|
||
Optical Transition Radiation (OTR) screen represents the most appropriate instrument to measure and verify the characteristics of a beam spot size produced by a particle accelerator. In order to measure such beam properties, OTR screens have to sustain thermal and mechanical stresses due to the energy that several bunches deposit. Owing to these requirements, it is essential to identify the more suitable material to optimize the OTR dimensions and to get reliable measures from the diagnostic system. In this paper, we describe a numerical procedure to choose the most performing material taking into account the physical requirements of a multi-bunch high brightness. The procedure is based on a dedicated ANSYS script able to evaluate the fatigue life time of the material considering a high number of thermal cycles generated by several bunches. The main characteristic of this script is the capability to simulate the real thermal and mechanical effect on the target that the hitting particle beam produces. The numerical procedure has been applied to compare the performance of three relevant materials-Aluminium, Silicon and Graphite simulating a beam hitting with well-known parameters. | ||

SUSPFO037 | use link to see paper's listing under its alternate paper code | |
|
||
Operation of modern particle accelerators require high qualitity beams and conseguently sensitive diagnostic system in order to monitories and characterize the beam during the acceleration and transport. A turn-key high level software BOLINA (Beam Orbit for Linear Accelerators) has been developed to fully characterise the 6D beam phase space in order to help operator during commissioning with an easily scalable suite for any high brightness LINAC. In this work will be presented the diagnostic toolkit is presented as designed for the ELI-NP Gamma Beam System (GBS) a radiation source based on the Compton back scattering effect able to provide tunable gamma rays in the 0.2-20 MeV range with narrow bandwidth (0.3% and a high spectral density (104 photons/sec/eV) by the Compton backscattering effect. BOLINA suite is design to be machine independent, thanks to the file exchanges with the EPICS based control system. Simulation of raw data of the ELI-NP-GBS accelerator has been used to test the capabilities of the diagnostic toolkit. | ||
