LUNEX5 (free electron Laser Using a New accelerator for the Exploitation of X-ray radiation of 5th generation) aims at investigating the production of short, intense, and coherent pulses in the soft X-ray region. It comprises two types of accelerators connected to a single Free Electron Laser (FEL), enabling the most advanced seeding configurations : High order Harmonic in Gas (HHG) seeding and Echo Enable Harmonic Generation (EEHG) with cryogenic in-vacuum undulators. The 400 MeV Conventional Linear Accelerator (CLA) uses superconducting cavities, compatible with a future upgrade towards high repetition rate for investigating advanced FEL schemes. It will also enable multi-user operation by splitting part of the macropulse to different FEL lines. A 0.4 - 1 GeV Laser Wake Field Accelerator (LWFA) will also be qualified in view of FEL applications, in the single spike or seeded regime. After the Conceptual Design Report, R&D has been launched on a cryo-ready 3 m long in-vacuum undulator, variable strong permanent magnet quadrupoles, Smith-Purcell and electro-optics diagnostics. A test experiment is also under preparation for validating the computed beam transport from the LWFA.

Supratech is a facility at CEA/Saclay that enables tests on superconducting and high power RF components for particle accelerators. The facility comprises a home-made hard tube HV modulator powering up to 95kV-20A at 2.1ms/50Hz and a 700MHz pulsed klystron developed by CPI able to produce RF up to 1MW-2ms/50Hz. A new compact HV and RF interlock system including klystron HV diagnostics has been implemented on Supratech test facility. This paper describes in more detail the klystron interlock system and the results of the first tests.

The accelerator of the European Spallation Source (ESS) is a 5 MW proton linac to be built in Lund Sweden. Its superconducting section is composed of 3 cavity families: double spoke resonators, medium beta and high beta elliptical multicell cavities. This paper presents the electromagnetic and mechanical design of the 704.42 MHz elliptical cavities. Both elliptical famillies are housed in 4-cavity cryomodules which share a common design and set of components which will be described here.
