“…The idea of photon-assisted vortex de-pairing in superconductors strips was introduced several decades ago as a possible consequence of the interaction between light and current-carrying superconductors [2]. The topic is of renewed research interest for a variety of advanced detection applications, including superconducting nanowires (SSPDs or SNSPDs) [3] for infrared single photon detection and microscopic superconducting strips for high energy (~ 20 KeV) particle or single molecule detection [4]. Such superconducting strips based devices can be fabricated with high yield over large areas with modern mico-and nanofabrication techniques.…”

We report an experimental investigation that shows how magnetic vortices are generated and cross a currentcarrying superconducting strip when illuminated by a bright (~MeV) and fast (<500 ps duration) infrared light pulse. The work has been carried out using a strike-and-probe electro-optic technique on a device consisting of a parallel superconducting strip configuration, with wide spacing between the strips to allow the interaction of the photons with single strip. We find that photons hitting one strip induce a collective current redistribution in the parallel strips, which we can quantitatively account for in the framework of the London model by including the effect of generated and trapped magnetic vortices in the superconducting loops formed by the two adjacent slots. The amount of trapped vorticity and its dependence on increasing current density flowing in the illuminated strip is in good agreement with the photon-assisted unbinding of vortex-antivortex pairs. This work allows us to gain a deeper understanding of the interaction between photons and current-carrying superconducting strips.

“…5) Compared with avalanche photodiodes (APDs) and photomultiplier tubes (PMTs), SNSPD has many merits in near-infrared wavelength such as a negligible dark count rate (<10 Hz), a small timing jitter (~50 ps), a high counting rate (>1 GHz), and a high quantum efficiency (>25%). 6,7) For practical application of SNSPD, there are a few issues that need to be solved or further studied, for example, the photon number resolution ability, the kinetic inductance, the timing jitter, and the latching behavior.…”

Abstract:Latching is a serious issue in superconducting nanowire single-photon detector (SNSPD) technology. By extensively studying the electrical transportation characteristics of SNSPD with different bias schemes, we conclude that latching is a result of the improper bias to SNSPD. With the quasi-constant-voltage bias scheme, the intrinsic nonlatching nature of SNSPD is observed and discussed. The SNSPD working in the nonlatching bias shows a smaller jitter and a higher pulse amplitude than that in the previous anti-latching method. The quantum efficiency of SNSPD with the pulsed photon frequency up to 3 GHz is measured successfully, which further proves the nonlatching operation of SNSPD.

“…As described in Section 3, the first SSPD for TOF-MS had a sensitive area of 50×50 µm 2 and showed a τ r of 360 ps and pulse decay time, τ d , of 9 ns [7]. …”

“…[7] and [37] and the result is shown in figure 5, which shows the mass spectrum of a peptide, results were promising because of the good quantum efficiency, the fast response capability and the operating temperatures (2 -5 K). Nevertheless, it was not easy to scale the detector area to larger sizes because the meander geometry is severely limited by the kinetic inductance that is proportional to the strip length: the largest SSPD had the worst response time.…”

We review progress in the development and applications of superconducting nano-strip particle detectors. Particle detectors based on superconducting nano-strips stem from the parent devices developed for single-photon detection (SSPD) and share with them ultrafast response time (sub-nanosecond) and operation at a relatively high temperature (2 -5 K) with respect to other cryogenic detectors. SSPDs have been used in the detection of electrons, neutral and charged ions, and biological macromolecules. Nevertheless, the development of superconducting nano-strip particle detectors has been mainly driven by the use in time-of-flight mass spectrometers (TOF-MS) where the goal of 100% efficiency at large mass values can be obtained. A special emphasis will be given to this case, reporting the great progress achieved which permits to overcome the limitations of existing mass spectrometers represented by low detection efficiency at large masses and charge/mass ambiguity and could represent a breakthrough in the field. In this review article we will introduce the device concept and detection principle, stressing the peculiarities of the nano-strip particle detector as well as its similarities with the photon detector. The development of the parallel strip configuration is introduced and extensively discussed, since it has contributed to significant progress in TOF-MS applications.
