摘要：

In this work, we describe the optical properties of the single photoelectron (SPE) calibration system designed for NectarCAM, a camera proposed for the Medium Sized Telescopes (MST) of the Cherenkov Telescope Array (CTA). One of the goals of the SPE system, as integral part of the NectarCAM camera, consists in measuring with high accuracy the gain of its photo-detection chain. The SPE system is based on a white painted screen where light pulses are injected through a fishtail light guide from a dedicated flasher. The screen - placed 15 mm away from the focal plane - is mounted on an XY motorization that allows movements over all the camera plane. This allows in-situ measurements of the SPE spectra via a complete scan of the 1855 photo-multiplier tubes (PMTS) of NectarCAM. This calibration process will enable the reduction of the systematic uncertainties on the energy reconstruction of gamma-rays coming from distant astronomical sources and detected by CTA. We discuss the design of the screen used in the calibration system and we present its optical performances in terms of light homogeneity and timing of the signal.
