Stray light analysis of the optical chamber at the PANTER X-ray test facility

Accurate characterization and control of stray light are crucial in ensuring the precision and reliability of the test facilities. This paper focuses on the comprehensive stray light analysis conducted on the optical chamber at the PANTER test facility. Employing simulation tools and observation results, the study investigates the potential sources and pathways of stray light within the optical chamber, which possibly interferes with the performance verification of the X-ray optics. Results from the study provide valuable insights into the stray light environment within the PANTER optical chamber, aiding in the optimization of testing conditions and contributing to the broader understanding of maintaining precision in optical measurements. This work is essential for enhancing the overall performance and reliability of future measurement and calibration campaigns.
