TESLA 2000 - 09 May 2000 A Test of the Laser Alignment System ALMY at the TTF - FEL
نویسندگان
چکیده
The laser alignment system ALMY was tested at the undulator section of the TESLA test facility. The positions of the undulator modules relative to each other have beendetermined with a precision of 0.1 mm, limited by the accuracy of the mechanical support of the sensors. Additionally, ALMY allows to measure movements or drifts over several days and we found that the undulator components are stable within 10 m. The resolution of the sensors is better than 2 m over the 15 m long alignment system.

Cavity-type Beam Position Monitors for the SASE FEL at the TESLA Test Facility
Cavity-type beam position monitors were developed to measure the beam alignment at the undulator section of DESY’s TESLA Test Facility (TTF). This paper describes some theoretical aspects and the experimental setup. The results of some in-beam measurements at the TTF are presented and pros and cons of the monitor concept are discussed.
متن کاملTest Results on the Silicon Pixel Detector for the TTF-FEL Beam Trajectory Monitor
Test measurements on the silicon pixel detector for the beam trajectory monitor at the free electron laser of the TESLA test facility are presented. To determine the electronic noise of detector and read-out and to calibrate the signal amplitude of different pixels the 6 keV photons of the manganese Kα/Kβ line are used. Two different methods determine the spatial accuracy of the detector: In on...
متن کاملWakefield Induced Correlated Energy Spread and Emittance Growth at TTF FEL
An electron beam with a small energy spread (0.1%) and a small normalized emittance (2 mm.mrad) is required to drive a Free Electron Laser at the TESLA Test Facility (TTF) at DESY. During FEL operations, the longitudinal and transverse wakefields which are generated by vacuum components, principally by RF cavities, bellows and valves, will induce an additional energy spread and emittance growth...
متن کاملOptimization of Beam Injection into the First Accelerating Module at Ttf with Cavity Dipole Mode Signals
The TESLA Test Facility (TTF) is a user facility for intense VUV-FEL light. The facility is densely equipped with diagnostics, essential in obtaining the necessary beam parameters, in particular the low emittance. However there is no dedicated component for alignment of the beam in the accelerating modules, each containing eight superconducting cavities. Large beam offsets can lead to an increa...
متن کاملDevelopment of a Femtosecond Soft X-ray SASE FEL at DESY
In this paper we describe the extension of the soft X-ray SASE FEL at the TESLA Test Facility (TTF) at DESY for generation of femtosecond pulses. The idea is based on a technique of \manipulating" the energy spread along the electron bunch. Since the radiation ampli cation process is extremely sensitive to the value of the energy spread, only that part of the electron bunch radiates which has l...
