We study photon count statistics in superconducting
single-photon detectors (SSPD) consisting of up to 70 narrow superconducting strips connected in parallel. Using inter-arrival
time analysis we demonstrate that our samples are operated in ‘arm-trigger’ regime and require up to 7 subsequently absorbed photons to form a resistive state in the whole sample. We also performed numerical simulation of the light and dark count rates vs detector bias current which are in good agreement with the experimental results.
