Description
The cryogenic beam vacuum system work package (WP 4) is developing a technical design concept for the FCC-hh beam screen based on the requirements and constraints that emerge from the arc design and magnets work packages (WP 2 and WP5). Within this framework, a measurement setup was designed with the goal of determining the photodesorpotion yield, synchrotron radiation heat loads and photo electron generation inside the FCC-hh beam screen prototype. Measurements on several beam screen setups, both at cryogenic and room temperature, will be carried out in the ANKA light source, which has a synchrotron radiation spectrum similar to FCC-hh. We present here a status report of the installation of the rst setup at ANKA, together with the results obtained after the conditioning of the installed equipment.
