Sentinel Watchdog Kit G2 GAGG
Beam stop with X-ray detector provides real-time X-ray beam monitoring and dosing information without interfering with diffraction data collection.
- Upgraded Scintillator (GAGG) and Housing (Tungsten)
- Continuously monitor beamline stability.
- Calibrate X-ray beam intensity.
- Record intensity during data collection and determine exact sample radiation dose exposure.
- Micro-sized for minimum shadowing of the diffraction pattern.
