“…In 2021, the installation of a bunch compressor [41] and the Polarix TDS [6] will bring ARES closer to the goal of generating and characterizing fs to sub-fs short electron bunches. New diagnostics, such as the low-charge, beam profile monitor STRIDENAS (Strip Detector for Novel Accelerators at SINBAD) will be tested in the future [42].…”

Over the years, the generation and acceleration of ultra-short, high quality electron beams has attracted more and more interest in accelerator science. Electron bunches with these properties are necessary to operate and test novel diagnostics and advanced high-gradient accelerating schemes, such as plasma accelerators and dielectric laser accelerators. Furthermore, several medical and industrial applications require high-brightness electron beams. The dedicated R&D facility ARES at DESY (Deutsches Elektronen-Synchrotron) will provide such probe beams in the upcoming years. After the setup of the normal-conducting, radio-frequency (RF) photoinjector and linear accelerating structures, ARES successfully started the beam commissioning of the RF gun. This paper gives an overview of the ARES photoinjector setup and summarizes the results of the gun commissioning process. The quality of the first electron beams is characterized in terms of charge, momentum, momentum spread and beam size. Additionally, the dependencies of the beam parameters on RF settings are described. All measurement results of the characterized beams fulfill the requirements for operating the ARES linac with this RF photoinjector.

Over the last years, the generation and acceleration of ultra-short, high quality electron beams has attracted more and more interest in accelerator science.

“…In this context, a collaboration between DESY, PSI and CERN was established to develop and build an advanced modular X-band TDS system which included the novel feature of providing variable polarization of the deflecting force. The possibility of changing the orientation of the streaking field to an arbitrary azimuthal angle opens new opportunities for extended beam characterization which makes particular use of the variable streaking direction, such as 5D phase-space characterization 23 or the retrieval of the three-dimensional charge distribution. 24 Combining these novel and more extended beam characterizations with the capability of achieving sub-fs temporal resolution, this diagnostic tool will be able to provide new insight on the multidimensional beam phase-space characterization with sub-fs resolution.…”

X-Ray Free-Electron Lasers: Advances in Source Development and Instrumentation VI

Radiofrequency (RF) transverse deflection structures (TDSs) are fundamental time-resolved diagnostics in x-ray free-electron lasers. Two x-band TDSs with variable polarization of the deflecting force were recently installed after the undulators of Athos, the soft x-ray beamline of SwissFEL. This contribution summarizes the experience gained over the last few months during the commissioning of the RF system and the measurements made during operations, focusing on the setup of the entire complex RF system, the calibration and the time-resolved measurement that, combined with an energy spectrometer, provides longitudinal phase-space measurements of extreme importance for the commissioning of the complex FEL schemes implemented in the Athos beamline.
