Abstract

For better tuning and control of the longitudinal beam parameters two Bunch Shape Monitors (BSM) and one Bunch Length and Velocity Detector (BLVD) have been developed and installed in the DESY H/sup -/ linac (Linac-III). The BSMs have a standard function to measure the longitudinal distribution of particles in bunches and the mechanical layout has been optimized in order to fit the extremely narrow space between the DTL tanks. The BLVD has an additional feature to measure the beam absolute energy and is installed downstream of the linac. Due to the use of a thin wire as a source of secondary electrons the devices can be used as a nondestructive beam diagnostic tool during linac operation. The performance of the BSMs as well as the results of the Linac-III beam studies using the new devices are presented.
