Abstract: Night Sky Background (NSB) is a complex phenomenon, consisting of all light detected byImaging Atmospheric Cherenkov Telescopes (IACTs) not attributable to Cherenkov light emission.Understanding the effect of NSB on cameras for the next-generation Cherenkov Telescope Array(CTA) is important, as it affects the systematic errors on observations, the energy threshold, thethermal control of the cameras and the ability of the telescopes to operate under partial moonlightconditions. This capacity to observe under partial moonlight conditions is crucial for the CTAtransient science programme, as it substantially increases the potential observing time. Usingtools initially developed for H.E.S.S. (in combination with the prototype CTA analysis packagectapipe) we will present predictions for the NSB present in images taken by the CTA Small SizedTelescope Camera (SSTCAM), showing that SSTCAM will likely be able to meet the associatedCTA requirements. Additionally, we calculate the potential observing time gain by operatingunder high NSB conditions.
