For the first time in the history of ground-based y-ray astronomy, the on-axis performance of the dual mirror, aspheric, aplanatic Schwarzschild-Couder optical system has been demonstrated in a 9:7-m aperture imaging atmospheric Cherenkov telescope. The novel design of the prototype Schwarzschild-Couder Telescope (pSCT) is motivated by the need of the next-generation Cherenkov Telescope Array (CTA) observatory to have the ability to perform wide (≥8°) field-of-view observations simultaneously with superior imaging of atmospheric cascades (resolution of 0:067 per pixel or better). The pSCT design, if implemented in the CTA installation, has the potential to improve significantly both the x-ray angular resolution and the off-axis sensitivity of the observatory, reaching nearly the theoretical limit of the technique and thereby making a major impact on the CTA observatory sky survey programs, follow-up observations of multi-messenger transients with poorly known initial localization, as well as on the spatially resolved spectroscopic studies of extended x-ray sources. This contribution reports on the initial alignment procedures and point-spread-function results for the challenging segmented aspheric primary and secondary mirrors of the pSCT.
The Cherenkov Telescope Array (CTA) will be the future observatory for ground-based TeV gamma-ray astronomy. At two sites, one in the northern and one in the southern hemisphere, CTA will feature about one hundred telescopes of different size classes in order to significantly improve the sensitivity and energy range with respect to current Cherenkov facilities. FlashCam is a camera system proposed for the medium-sized telescopes of CTA that implements a fully-digital readout and trigger processing, which allows the reconfiguration of the trigger algorithm and the signal shaping. For the mass production of a substantial number of FlashCam cameras, efficient and reliable testing routines have been developed. In this contribution, the concept and the procedures for large-scale testing of the readout electronics are outlined. Additionally, a fast multi-channel pulse generator specifically designed for the functional testing of FlashCam FADC modules setup is presented.
