NectarCAM is a Cherenkov camera that will be installed on Medium-Sized Telescopes of the
northern array of the Cherenkov Telescope Array Observatory (CTAO). It is composed of 265
modules, each of which includes 7 photo-multiplier tubes, a Front-End Board and a camera
trigger system for data collection. The first NectarCAM unit is currently being integrated at
CEA Paris-Saclay in France. Once installed at the CTAO’s northern site, the NectarCAM’s timing
abilities will be crucial for reducing noise in images, improving image cleaning, and distinguishing
between gamma-ray photons and cosmic-ray background. Additionally, it will enable coincidence
identification with neighboring telescopes for stereoscopic observations. The timing system of
NectarCAM has been tested in a dark room with various light sources. The results of the tests,
including timing precision and accuracy of the trigger arrival relative to a laser source, and the
timing of individual and multiple pixel signals, will be presented.
