Contribution
It introduces the use of diamond detector blades for XBPMs, providing a novel approach to improve performance over existing photoemission-based monitors.
Findings
Diamond detector blades can enhance XBPM performance.
Analysis shows potential to overcome photoemission XBPM drawbacks.
Optimization based on signal spatial distribution calculations.
Abstract
Optimization of blade type X-ray Beam Position Monitors (XBPM) was performed for NSLS-II undulator IVU20. Blade material, configuration and operation principle was analyzed to improve XBPM performance. Optimization is based on calculation of the XBPM signal spatial distribution. Along with standard photoemission blades, Diamond Detector Blade (DDB) was analyzed as XBPM signal source. Analyses revealed, that Diamond Detector Blade XBPM would allow overcoming drawbacks of the photoemission type XBPMs.
