%X We have developed a cryogenic measurement system for single-photon counting, which can be usedin optical experiments requiring high time resolution in the picosecond range. The system utilizesniobium nitride superconducting nanowire single-photon detectors which are integrated in a timecorrelatedsingle-photon counting (TCSPC) setup. In this work, we describe details of the mechanicaldesign, the electrical setup, and the cryogenic optical components. The performance of the completesystem in TCSPC mode is tentatively benchmarked using 140 fs long laser pulses at a repetitionfrequency of 75MHz. Due to the high temporal stability of these pulses, the measured time resolutionof 35 ps (FWHM) is limited by the timing jitter of the measurement system. The result was crosscheckedin a Coherent Anti-stokes Raman Scattering (CARS) setup, where scattered pulses from aβ-barium borate crystal have been detected with the same time resolution.
