Phys. Lett.", year="2012", volume="101", optkeywords="SSPD; SNSPD; x-ray; Nb", abstract="Although superconducting nanowire single-photon detectors (SNSPDs) are well studied regarding thedetection of infrared/optical photons and keV-molecules, no studies on continuous x-ray photoncounting by thick-film detectors have been reported so far. We fabricated a 100 nm thick niobiumx-ray SNSPD (an X-SNSPD) and studied its detection capability of photons with keV-energies incontinuous mode. The detector is capable to detect photons even at reduced bias currents of 0.4{\%},which is in sharp contrast to optical thin-film SNSPDs. No dark counts were recorded in extendedmeasurement periods. Strikingly, the signal amplitude distribution depends significantly on the photonenergy spectrum.VC", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=878), last updated on Tue, 30 Oct 2012 16:06:57 -0500" }
