Title :
Beam position monitors in the TESLA Test Facility linac

Abstract :
The transverse position of the beam in the TTF linac will be measured using two different types of monitors. For the alignment of the quadrupoles, a circular cavity was designed because of the desired resolution of 10 μm and the limited longitudinal space. The amplitude of the TM110-mode will be measured in a homodyne receiver, using a signal from the timing system as a reference. Stainless steel prototypes were tested. Furthermore, the single bunch behaviour was measured at the CLIC Test Facility. Coaxial striplines will be installed in the experimental area, having a resolution of better than 100 μm. The averaged position of the whole bunch train or the position of an individual bunch will be measured using the amplitude-to-phase conversion
