Recent development of the LED based monitoring system for CALIFA CALorimeter for In flight detection of γ rays and high energy charged pArticles — •Christian Sürder, Anna-Lena Hartig, Alexander Ignatov, Thorsten Kröll, and Han-Bum Rhee for the R3B collaboration — Institut für Kernphysik, Technische Universität Darmstadt, Darmstadt, Deutschland
CALIFA is part of the R3B setup of the future FAIR facility. The used detector units consisting out of an Avalanche Photo Diode and a CsI(Tl) scintillation crystal. With these detector units it is possible to built a high resolution calorimeter, which is insensitive to present magnetic fields. It is common to monitor the properties of a calorimeter with a corresponding monitoring system. For CALIFA it was decided to implement a LED based monitoring system, which delivers a light pulse via plastic optical fibers to monitor the detection process starting from the scintillation crystal. To have control over the LED source, a reference system with a detector and a standard radioactive source runs alongside. The recent status and the developments of this system will be presented.
