Response to a single absorbed photon appears due to successive formation of a normal spot and phase-slip-centres in a narrow strip carrying sub-critical supercurrent. The detector simultaneously has a moderate energy resolution and a variable cut-off wavelength depending on both the material used and operation conditions. We simulated performance of the background-limited direct detector having the 100-micrometer cut-off wavelength. Low dark count rate will allow to realise 10-21 W Hz-1/2 noise equivalent power at 4 K background radiation. The detection mechanism provides a moderate 1/20 energy resolution at 50-micrometer wavelength.", optnote="Volume: 211408", optnote="exported from refbase (https://db.rplab.ru/refbase/show.php?record=1538), last updated on Fri, 21 May 2021 16:36:30 -0500", opturl="https://elib.dlr.de/18596/" }
