Title: Characterization of TimepixCam, a fast imager for the time-stamping of optical photons

Here we describe the characterization of TimepixCam, a novel camera used to time-stamp optical photons. The camera employs a specialized silicon sensor with a thin entrance window, read out by a Timepix ASIC. TimepixCam is able to record and time-stamp light flashes exceeding 1,000 photons with 15 ns time resolution. Specially produced photodiodes were used to evaluate the quantum efficiency, which was determined to be higher than 90% in the wavelength range of 430–900 nm. The quantum efficiency, sensitivity and ion detection efficiency were compared for a variety of sensors with different surface treatments. We found sensors with the thinnest window, 50 nm, had the best performance.
