Beamstopper-Integrated Sensors (BIS) based on silicon carbide (SiC) represent a novel class of compact, radiation hard devices that combine beam interception with real-time diagnostics. We present the first characterization of fourquadrant BIS designed for simultaneous intensity and position monitoring on synchrotron beamlines. Based on the established reliability of single-pixel BIS as intensity monitors at SLS, we demonstrate quadrant-resolved response and linearity with photon flux, despite minor contacting issues in one channel. These results establish SiC BIS as robust, visible-blind diagnostics, leading the way for deployment of position-sensitive BIS in high-brilliance undulator experiments.

Abstract
Beamstopper-Integrated Sensors (BIS) based on silicon carbide (SiC) represent a novel class of compact, radiation hard devices that combine beam interception with real-time diagnostics. We present the first characterization of fourquadrant BIS designed for simultaneous intensity and position monitoring on synchrotron beamlines. Based on the established reliability of single-pixel BIS as intensity monitors at SLS, we demonstrate quadrant-resolved response and linearity with photon flux, despite minor contacting issues in one channel. These results establish SiC BIS as robust, visible-blind diagnostics, leading the way for deployment of position-sensitive BIS in high-brilliance undulator experiments.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
