Investigation of magnetic-field effects on photomultiplier tubes for the first Large-Sized Telescope of the Cherenkov Telescope Array Observatory

Yukiho Kobayashi, Dai Tateishi, Yuji Sunada +28

Photomultiplier tubes (PMTs) are widely used in imaging atmospheric Cherenkov telescopes. Their response can depend on the telescope pointing direction through changes in their ori…

Multimodal Shifts in the Dark Current of Silicon Photomultipliers

Ryu Kawarasaki, Akira Okumura, Kazuhiro Furuta +1

The dark count rate is one of the key properties of avalanche photodiodes (APDs) and silicon photomultipliers (SiPMs). Previous studies have reported discrete shifts in the dark co…

Competition between Increasing and Decreasing Effects of the Afterpulsing Rate of PMTs during Night-Sky Observations

Takuto Kiyomoto, Tsutomu Nagayoshi, Shunsuke Sakurai +13

Photomultiplier tubes (PMTs) have been widely used in imaging atmospheric Cherenkov telescopes (IACTs). The Large-Sized Telescopes (LSTs) of the Cherenkov Telescope Array Observato…

Imaging Atmospheric Cherenkov Telescopes pointing determination using the trajectories of the stars in the field of view

Mykhailo Dalchenko, Matthieu Heller

We present a new approach to the pointing determination of Imaging Atmospheric Cherenkov Telescopes (IACTs). This method is universal and can be applied to any IACT with minor modi…
