“…Fabry-Perot resonators are indeed best suited for high repetition rate lasers (above tens of megahertz) because the laser oscillator has to be locked to the cavity round-trip frequency with a very high accuracy and therefore with a feedback bandwidth between 10 kHz-1 MHz. Two-and four-mirror cavities have been successfully used to produce γ-ray beams in the continuous [12,13] and high repetition rate regime [14,15]. Another technique, namely the amplifier burst mode [16], is also being investigated but very few results have been reported so far.…”

A new kind of nonresonant optical recirculator, dedicated to the production of γ rays by means of Compton backscattering, is described. This novel instrument, inspired by optical multipass systems, has its design focused on high flux and very small spectral bandwidth of the γ-ray beam. It has been developed to fulfill the project specifications of the European Extreme Light Infrastructure "Nuclear Pillar," i.e., the Gamma Beam System. Our system allows a single high power laser pulse to recirculate 32 times synchronized on the radio frequency driving accelerating cavities for the electron beam. Namely, the polarization of the laser beam and crossing angle between laser and electrons are preserved all along the 32 passes. Moreover, optical aberrations are kept at a negligible level. The general tools developed for designing, optimizing, and aligning the system are described. A detailed simulation demonstrates the high efficiency of the device.

A conceptual design is presented of a novel energy-recovering linac (ERL) facility for the development and application of the energy recovery technique to linear electron accelerators in the multi-turn, large current and large energy regime. The main characteristics of the powerful energy recovery linac experiment facility (PERLE) are derived from the design of the Large Hadron electron Collider, an electron beam upgrade under study for the LHC, for which it would be the key 11 Author to whom any correspondence should be addressed.Original content from this work may be used under the terms of the Creative Commons Attribution 3.0 licence.

PERLE is thus projected as a facility to investigate efficient, high current (HC) (>10 mA) ERL operation with three re-circulation passages through newly designed SCRF cavities, at 801.58 MHz frequency, and following deceleration over another three re-circulations. In its fully equipped configuration, PERLE provides an electron beam of approximately 1 GeV energy. A physics programme possibly associated with PERLE is sketched, consisting of high precision elastic electron-proton scattering experiments, as well as photo-nuclear reactions of unprecedented intensities with up to 30 MeV photon beam energy as may be obtained using Fabry-Perot cavities. The facility has further applications as a general technology test bed that can investigate and validate novel superconducting magnets (beam induced quench tests) and superconducting RF structures (structure tests with HC beams, beam loading and transients). Besides a chapter on operation aspects, the report contains detailed considerations on the choices for the SCRF structure, optics and lattice design, solutions for arc magnets, source and injector and on further essential components. A suitable configuration derived from the here presented design concept may next be moved forward to a technical design and possibly be built by an international collaboration which is being established.

“…The linear accelerator will produce a 70 MeV electron beam which will be injected in the compact storage ring (greater diagonal of about 7 m length). The X-rays will be produced with the interaction between electrons and photons coming from an amplified laser within a FabryPerot cavity [4]. The purpose of ThomX is to demonstrate that historical heritage study and Xray imaging can be affordable for a museum, or a large hospital, due to the compactness of the installation.…”

Abstract. The Institut de physique nucléaire -Institute of Nuclear Physics (IPN) and the Laboratoire de l'accélérateur linéaire -Laboratory of the linear accelerator (LAL) are about to build two accelerators at the University Paris-Sud, Orsay. Andromede is a new imaging mass spectrometry instrument for surface analysis: the electron positron emission microscope (EPEM) will analyse impacts on a surface made by nano-particles (Au404) in the keV to MeV range to study ion-surface interactions. ThomX is a compact X-ray source (energy up to 90 keV -flux up to 10 13 photons.s -1 ) that will produce X-rays using Compton backscattering effect between an electron beam and a laser. In order to use these machines in the same area, hutches are designed to comply with French regulations for radiation protection. This paper presents the methods used to design the hutches, complying with safety objectives, technical issues and budget.
