Description
The MAGIC telescopes on La Palma detect Cherenkov radiation induced by particle showers. Photomultiplier tubes (PMTs) are currently used as photodetectors. In order to extend the duty cycle of such telescopes and improve their general robustness the use of silicon based photodetectors (SiPMs) is tested.
As part of achieving a better understanding of operation of SiPMs in Imaging Atmospheric Cherenkov Telescopes (IACTs) the mean arrival time of signals detected by the SiPMs and their timespread are analyzed and compared to the data produced by the PMTs.
To reduce the costs of the camera, in a previous work the design of the lightguides, that collimate photons towards the detectors, has been adjusted. After being installed in the camera their performance is checked against the more complex lightguide design. The objective is to have no severe loss in light intensity and at the same time no increase in background light.
