Electron beam characterization of a combined diode rf electron gun

Christoph Peter Hauri, Stefan Yves Gabriel Binder, Rasmus Ischebeck

Experimental and simulation results of an electron gun test facility, based on pulsed diode acceleration followed by a two-cell rf cavity at 1.5 GHz, are presented here. The main features of this diode-rf combination are: a high peak gradient in the diode ...

Wavelength-tunable UV laser for electron beam generation with low intrinsic emittance

Christoph Peter Hauri, Rasmus Ischebeck

We developed a powerful UV laser at a central wavelength varying from 260-283 nm. The laser system based on a frequency-trippled Ti:sapphire amplifier delivers mJ pulse energy within a duration of 1-10 ps (fwhm) with 1.5 nm spectral width (fwhm). The syste ...

Generation and measurement of sub-micrometer relativistic electron beams

Rasmus Ischebeck, Eugenio Ferrari

The generation of low-emittance electron beams has received significant interest in recent years. Driven by the requirements of X-ray-free electron lasers, the emittance of photocathode injectors has been reduced significantly, with corresponding increase ...

The ACHIP experimental chambers at the Paul Scherrer Institut

Rasmus Ischebeck, Eugenio Ferrari, Leonid Rivkin

The Accelerator on a Chip International Program (ACHIP) is an international collaboration, funded by the Gordon and Betty Moore Foundation, with the goal of demonstrating that laser-driven accelerator can be integrated on a chip to fully build an accelerat ...

High-precision x-ray FEL pulse arrival time measurements at SACLA by a THz streak camera with Xe clusters

Junqiu Liu, Christoph Peter Hauri, Rasmus Ischebeck, Leonid Rivkin, Ishkhan Gorgisyan

The accurate measurement of the arrival time of a hard X-ray free electron laser (FEL) pulse with respect to a laser is of utmost importance for pump-probe experiments proposed or carried out at FEL facilities around the world. This manuscript presents the ...

The SwissFEL soft X-ray free-electron laser beamline: Athos

Christoph Bostedt, Christopher Alexander Arrell, Rasmus Ischebeck, Eugenio Ferrari, Thomas Schmidt

The SwissFEL soft X-ray free-electron laser (FEL) beamline Athos will be ready for user operation in 2021. Its design includes a novel layout of alternating magnetic chicanes and short undulator segments. Together with the APPLE X architecture of undulator ...

A scheme for a shot-to-shot, femtosecond-resolved pulse length and arrival time measurement of free electron laser x-ray pulses that overcomes the time jitter problem between the FEL and the laser

Christoph Peter Hauri, Fernando Ardana Lamas, Rasmus Ischebeck, Ishkhan Gorgisyan

The recent entry of X-ray free electron lasers (FELs) to all fields of physics has created an enormous need, both from scientists and operators, for better characterization of the beam created by these facilities. Of particular interest is the measurement ...

A compact and cost-effective hard X-ray free-electron laser driven by a high-brightness and low-energy electron beam

Majed Chergui, Christoph Peter Hauri, Christopher Alexander Arrell, Giulia Fulvia Mancini, Leonid Rivkin, Rasmus Ischebeck, Eugenio Ferrari, Camila Bacellar Cases Da Silveira, Mike Seidel, Thomas Schmidt

We present the first lasing results of SwissFEL, a hard X-ray free-electron laser (FEL) that recently came into operation at the Paul Scherrer Institute in Switzerland. SwissFEL is a very stable, compact and cost-effective X-ray FEL facility driven by a lo ...
