Development of a calibration light source based on a unique modification of an integrating sphere

Popis výsledku v původním jazyce

The precise determination of the energy scale is of utmost importance for many experiments in astroparticle physics. Thus, the detectors of such experiments have to be properly calibrated. This paper focuses on the complex but cost-effective modification of a general purpose integrating sphere to develop a calibration light source. The key parameter of the calibration light source is the radiance uniformity, which is optimized using a validated optical simulation model. Based on the results of the optical simulation, a prototype of a modified integrating sphere is assembled in our laboratory. Its radiance uniformity is subsequently measured and crosschecked with the optical simulation, proving the concept of the optimization. The achieved improvement in the radiance uniformity is discussed and demonstrated by a comparison of the results of the developed prototype with the results of the general purpose integrating sphere.
