TTF Beam Trajectory Monitor

Project Goal:

Development and realization of TTF-FEL beam trajectory monitor using silicon pixel detectors sensitive to soft X-Rays.

Project Status:

Finished in 2003

In order to achieve the high brightness promised by the single-pass Free Electron Laser (FEL) at the TESLA Test Facility (TTF) at DESY, the electron beam position must be controlled better than 10 μm over a distance of 15 m. The silicon pixel detector, which is critical to this monitor, must have a position resolution of 1 µm and an excellent sensitivity for soft X-rays above 150 eV.
