Journal ArticleDOI
First lasing of the darmstadt cw free electron laser
M. Brunken,Steffen Döbert,Ralf Eichhorn,Harald Genz,Hans-Dieter Gräf,H. Loos,Achim Richter,B. Schweizer,A. Stascheck,T. Wesp +9 more
TL;DR: The Darmstadt linac-based FEL as discussed by the authors was designed for wavelengths between 3 and 10 μm driven by the superconducting electron accelerator S-DALINAC first lased on December 1st, 1996 and has operated thereafter successfully in the wavelength region between 6.6 and 7.8 μm.
Journal ArticleDOI
Status and recent developments at the polarized-electron injector of the superconducting Darmstadt electron linear accelerator S-DALINAC
Y. Poltoratska,C. Eckardt,Wolfgang Ackermann,K. Aulenbacher,Thore Bahlo,R. Barday,M. Brunken,C Burandt,Ralf Eichhorn,Joachim Enders,M. Espig,Sylvain Sebastian Franke,C. Ingenhaag,J. Lindemann,Wolfgang Franz Otto Müller,M. Platz,M. Roth,F. Schneider,Michael Wagner,A. Weber,Thomas Weiland,B. Zwicker +21 more
TL;DR: In this article, the authors report on the performance of the teststand, simulations, developments on the laser systems, new radio-frequency components for the S-DALINAC injector, and the status of the implementation of the source.
Results from a 850 c heat treatment and operational findings from the 3 ghz srf cavities at the s-dalinac*
Ralf Eichhorn,Asim Araz,M. Brunken,Jens Conrad,Hans-Dieter Gräf,M. Hertling,Florian Hug,Martin Konrad,Thorsten Kürzeder,M. Platz,Achim Richter,Sven Sievers,Tobias Weilbach +12 more
TL;DR: In this article, a gas analysis during the heat treatment procedure showed that the cavities were strongly contaminated which might explain the low field flatness of the 20 cell elliptical cavities.
Journal ArticleDOI
3 GHz digital rf control at the superconducting Darmstadt electron linear accelerator: First results from the baseband approach and extensions for other frequencies
Araz Araz,Uwe Bonnes,Ralf Eichhorn,Florian Hug,Martin Konrad,M. Platz,Achim Richter,Rolf Stassen +7 more
TL;DR: In this article, the authors present the concept of the digital low-level rf control loops in detail and report on the results gained during first operation with a superconducting cavity.
Proceedings ArticleDOI
New injector cryostat module based on 3 GHz SRF cavities for the S-Dalinac
TL;DR: The Darmstadt electron linear accelerator S-DALINAC as mentioned in this paper was designed to accelerate electron beams with gradients up to 5 MV/m at a frequency of 3 GHz.
