Sensitivity and Tolerance Analysis of a New Bunch Arrival Time Monitor Pickup Design for Flash and Xfel
نویسندگان
چکیده
New pickup designs for a Bunch Arrival time Monitor (BAM) at the Free Electron Laser in Hamburg (FLASH) have been developed and simulated [1, 2] with CST PARTICLE STUDIO R ©. With regard to the signal characteristics and manufacturability a cone-shaped pickup was selected as a prospective candidate. At high frequencies, small manufacturing tolerances might have great influence on the pickup signal. A sensitivity analysis considering several manufacturing tolerances regarding their influence on the output signal was carried out. It shows that the output signal is insensitive with respect to manufacturing tolerances of most geometrical parameters.

Bpms for the Xfel Cryo Module
The European XFEL is based on superconducting accelerator technology developed in the context of the TESLA collaboration [1]. The accelerator itself consists of cryo modules equipped with 8 cavities, followed by a quadrupole/steerer package, a BPM and a HOM absorber. This contribution will present the layout of the BPM system for the cryo modules, describing the monitor itself, its integration ...
متن کاملComparative Study of Bunch Length and Arrival Time Measurements at Flash
Diagnostic devices to precisely measure the longitudinal electron beam profile and the bunch arrival time require elaborate new instrumentation techniques. At FLASH, two entirely different methods are used. The bunch profile can be determined with high precision by a transverse deflecting RF structure, but the method is disruptive and does not allow to monitor multiple bunches in a macro-pulse ...
متن کاملFemtosecond Resolution Bunch Arrival Time Monitor
A need for femtosecond resolution beam arrival time measurements has arisen with the transition from manypicosecond-long bunches in ring-based accelerators to a few femtosecond-long bunches in high-gain free-electron lasers. Here we present an electro-optical detection scheme that uses the signal of a beam pick-up to modulate the intensity of a femtosecond laser pulse train. By detecting the en...
متن کاملHigh Precision Sc Cavity Diagnostics with Hom Measurements
Experiments at the FLASH linac at DESY have demonstrated that the Higher Order Modes induced in Superconducting Cavities can be used to provide a variety of beam and cavity diagnostics. The centers of the cavities can be determined from the beam orbit which produces minimum power in the dipole HOM modes. The phase and amplitude of the dipole modes can be used as a high resolution beam position ...

The bunch arrival monitor (BAM) for the IV generation synchrotron light source FERMI@Elettra is presented. It is based on an original idea developed at FLASH/DESY, specifically designed and built in-house for FERMI@Elettra. Each BAM station consists of a frontend module, located in the machine tunnel, and of a backend unit located in the service area. It makes use of the pulsed optical phase re...
