MOPB15 | A Comparison of Front-End Design Requirements | 53 | |||
|
|||||
Front ends of the NSLS-II storage ring have numerous design requirements to ensure equipment and personal safety aspects of their designs. These design requirements, especially many pertaining to ray tracings, have gradually become overly stringent and a review is underway to simplify them for building future front ends. As a part of this effort we have assembled the front-end design requirements used in several other light sources. In this paper the assembled design requirements are discussed in comparison with those currently in use at NSLS-II. | |||||

WEOA03 | Updated High Heat Load Front-Ends for SLS 2.0 | 221 | |||
|
|||||
The Swiss Light Source (SLS) at the Paul Scherrer Institut (PSI) in Switzerland will undergo from 2021 to 2024 an upgrade named SLS 2.0 to increase brightness and coherence. This upgrade will have a significant impact on the existing front-ends. Due to the proven reliability and good concept, we plan a refurbishment strategy for all front-end (FE) components where possible. New source points for all beam-lines – resulting in shifts both lateral and tangential, newly developed insertion devices and bending magnets as well as spatial restrictions due to the multi bend achromat (MBA) design challenges this strategy. We demonstrate how we plan to deal with these challenges for the case of high heat load FEs. We will address how the acceptance of the FE was chosen due flux and power calculations of the insertion device and the design and thermal analysis of a novel primary aperture. The adaptions that will be made to the tungsten blade X-Ray beam positioning monitors (W-XBPM) and modifications on the photon shutter will be discussed. Furthermore, we will take a brief excursion on how we want to organize the refurbishment during the shutdown period of the upgrade. | |||||

Current Status of TPS XBPM System | ||||
|
|||||
The blade type X-ray beam position monitor is operating in the TPS front end. After a complete calibration process, the XBPM performed a high precision measurement for beam position monitor. This paper reports the current statuses of XBPMs in phase I TPS that discussed with the calibration method and the results after calibration. A long term record of photon beam stability will also be described in this paper. | |||||

Mechanical Aspects of the New Shutter Design at European XFEL | ||||
|
|||||
The European XFEL is a research facility which started operation in September 2017 and generates ultrashort X-ray flashes for photon science experiments with an outstanding peak brilliance. To operate the facility at full performance, an upgrade of the radiation safety system is needed. For this purpose nine Frontends and three Shutters have to be modified. This upgrade includes several mechanical changes like the replacement of the B4C absorber with a diamond and B4C absorber. Since also a new burn through monitor with a graphite block inside has to be installed in the absorber chamber the holder of the B4C has to be changed because of the space constraints in the chamber. This holder consists also of a special flexure plate fixed with springs and screws to allow a certain flexibility of the B4C. For attaching the CVDs to the absorber holder a special CVD clamp system has to be created to release the stress on the diamond and avoid their destruction. | |||||
