The REGAE Accelerator Vacuum System
9th International Particle Accelerator Conference, IPAC'18, VancouverVancouver, Canada, 29 Apr 2018 - 4 May 20182018-04-292018-05-04  GO
Since 2011 the Relativistic Electron Gun for Atomic Exploration (REGAE) is operated at DESY in Hamburg. The accelerator consists mainly of a high gradient S-band RF-gun, which generates ultra-low emittance electron bunches, and an S-band RF-buncher cavity for bunch compression. [...]

Status of the ARES RF Gun at SINBAD: From its Characterization and Installation Towards Commissioning
9th International Particle Accelerator Conference, IPAC'18, VancouverVancouver, Canada, 29 Apr 2018 - 4 May 20182018-04-292018-05-04 , 3 pp. () [10.3204/PUBDB-2018-01981]  GO
The SINBAD facility (Short and INnovative Bunches and Accelerators at DESY) is foreseen to host multiple experiments relating to the production of ultra-short electron bunches and novel high gradient acceleration techniques. The SINBAD-ARES linac will be a conventional S-band linear RF accelerator allowing the production of low charge (0.5 pC - tens pC) ultra-short electron bunches (FWHM length ≤ fs - few fs) with 100 MeV energy.

Analysis of the Production, Installation and Commissioning of the European-XFEL Frequency Tuners
18th International Conference on RF Superconductivity, SRF2017, LanzhouLanzhou, China, 17 Jul 2017 - 21 Jul 20172017-07-172017-07-21 JACoW , 5 pp. () [10.3204/PUBDB-2017-13966]  GO
In the European-XFEL superconducting linac, mechanical frequency tuners equipped with stepper motors and piezoelectric actuators provide cold tuning of each of the 768 1.3 GHz cavities. More than 820 complete tuning systems were fabricated and pre-assembled in industry, tested at several stages before and after assembly and successfully commissioned during cryo-module cold tests at AMTF (DESY).
