Funding: Work supported by the French Agence Nationale de la Recherche as part of the program EQUIPEX under reference ANR-10-EQPX-51, the Ile de France region, CNRS-IN2P3 and Université Paris Sud XI A collaboration of seven research institutes and an industry has been set up for the ThomX project, a compact Compton Backscattering Source (CBS) based in Orsay – France. After a period of study and definition of the machine performances a complete description of all the systems has been provided. The infrastructures work is started and the main systems are in the call for tender phase. In this paper we will illustrate the definitive machine parameters and components characteristics. We will also update the results of the different ongoing R&D on optical resonators, fast power supplies for the injection kickers and on the electron gun. |

Funding: Work is supported by the French "Agence Nationale de la Recherche" as part of the program "investing in the future" under reference ANR-10-EQPX-51, and also by grants from Region Ile-de-France. The Compton back-scattering based compact X-ray source ThomX is under construction in LAL/IN2P3, CNRS, France. This machine will serve as a demonstrator in producing up to 1013 ph/s for imaging and cultural heritage recovery. The high level applications of the ThomX machine for the future commissioning and operations are being developed using Matlab Middle Layer (MML) which is broadly used in the modern synchrotron light sources. In this article, we report the nearest progresses of high level applications of the ThomX machine, and present the nonlinear response matrices to correct the tune, chromaticity and orbit, and the algorithm to correct the orbit in the transfer line. |

The goal of 3-phase method is to determine the length of an electron beam without dedicated diagnostics by varying the measurement conditions of its energy spread, through a change in the RF phase of an accelerating structure. The originality here comes from the fact that it is applied on high-brightness electron beams of few MeV generated by RF photo-injectors. It allows testing the accuracy of 3-phase method, since the length to reconstruct is known as being that of the laser pulse generating the beam. It requires establishing the longitudinal transfer matrix of a RF photo-injector, which is difficult since the electron velocity vary from 0 to relativistic during its path*. The 3-phase method in RF photo-injector has been simulated by ASTRA and PARMELA codes, validating the principle of the method. First measurement has been done on PHIL accelerator at LAL, showing a good agreement with the expected length. I will then show results obtained at PITZ with a standing wave booster and a comparison with those coming from a Cerenkov detector. Finally, measurements at higher energy performed on the SOLEIL LINAC with travelling wave accelerating structures will be exposed.
