2014 19th IEEE-NPSS Real Time Conference
Year: 2014 | Conference Paper |
The European XFEL [1] timing system [2],[3] delivers drift-compensated precise timing and trigger information for its experiments. It consist of a double-size AMC module for micro-TCA crate system and complies with the MTCA.4 specifications. Clocks and triggers are delivered through the front-panel, the MTCA.4 backplane or through a Rear-Transition Module (RTM) connector. To accommodate the need f...Show More

Many applications require some type of phase detectors to determine the phase relation between synchronous clocks. The European XFEL timing system [1],[2],[3] utilizes numerous phase detectors to monitor and keep clocks and triggers phase stable.Modern digital systems are often based on FPGAs. These FPGAs could be used as phase detectors as well, with proper design considerations for the hardware ...Show More
Multi-Processor Based Fast Data Acquisition for a Free Electron Laser and Experiments

Free electron LASer in Hamburg (FLASH) at DESY is a user facility with laser-like radiation source in the VUV and soft X-ray range. It is also a pilot facility for the future XFEL. A fast data acquisition system (DAQ) to support the accelerator operation and the user experiments was developed. The system collects data from hundreds of ADC channels in the range of 1 M up to 2 G samples per second. ...Show More
Measurement of the beam's trajectory using the higher order modes it generates in a superconducting accelerating cavity

2007 IEEE Particle Accelerator Conference (PAC)
Year: 2007 | Conference Paper |
It is well known that an electron beam excites higher order modes (HOMs) as it passes through an accelerating cavity. The properties of the excited signal depend not only on the cavity geometry, but on the charge and trajectory of the beam. It is, therefore, possible to use these signals as a monitor of the beam's position. Electronics were installed on all forty cavities present in the FLASH lina...Show More

Beam position monitor calibration at the FLASH linac at DESY
N. Baboi;P. Castro;O. Hensler;J. Lund-Nielsen;D. Nolle;L. Petrosyan;E. Prat;T. Traber;M. Krasilnikov;W. Riesch
2007 IEEE Particle Accelerator Conference (PAC)
Year: 2007 | Conference Paper |
In the FLASH (free electron LASer in Hamburg) facility at DESY more than 60 BPMs (beam position monitors) with single bunch resolution are currently installed, and more are planned for future installation. Their calibration has been initially made by measuring each electronics board in the RF laboratory. However the ultimate calibration of each monitor is made by measuring its response to beam mov...Show More

The use of wake field acceleration basically is aimed to obtaining of high acceleration rate in comparison with traditional methods of acceleration. Meantime in the last years in YerPhI it was offered to use wake field acceleration for acceleration of high-current electron bunches on energy about 100 MeV. Experimental installation for research of formation of high-current electron bunches of the g...Show More
