Slow Halo Collimator Drives for SIS100

SIS100 will be equipped with a halo collimation system to remove unwanted halo particles and catch systematic losses caused by the extraction process. It is required to protect sensitive accelerator components from unavoidable beam loss. Among other components, the halo collimation system consists of moveable collimator blocks. The movability is realized by stepper motor drives with linear guiding systems. This tender includes seven drive systems with collimator blocks and mounting system. The mounting system allows an active cooling of the collimator blocks.
