Development and Performance of FlashCam

FlashCam is a high-performance, fully digital camera system developed for use in imaging atmospheric Cherenkov telescopes, particularly for the Medium-Sized Telescopes of the upcoming Cherenkov Telescope Array Observatory (CTAO). The camera features a fully digital trigger and readout architecture, enabling high event rates and precise control over the trigger system. A novel front-end electronics design provides a wide dynamic range of over 3,000 photoelectrons per pixel using a single readout channel, simplifying hardware without compromising performance. This contribution presents an overview of the development and performance of FlashCam, focusing on time reconstruction, charge reconstruction and temperature stability.

Abstract

FlashCam is a high-performance, fully digital camera system developed for use in imaging atmospheric Cherenkov telescopes, particularly for the Medium-Sized Telescopes of the upcoming Cherenkov Telescope Array Observatory (CTAO). The camera features a fully digital trigger and readout architecture, enabling high event rates and precise control over the trigger system. A novel front-end electronics design provides a wide dynamic range of over 3,000 photoelectrons per pixel using a single readout channel, simplifying hardware without compromising performance. This contribution presents an overview of the development and performance of FlashCam, focusing on time reconstruction, charge reconstruction and temperature stability.
