  • A measurement method for responsivity of microwave kinetic inductance detector by changing power of readout microwaves

    Superconducting detectors are a modern technology applied in various fields.
    The microwave kinetic inductance detector (MKID) is one of cutting-edge
    superconducting detector. It is based on the principle of a superconducting
    resonator circuit. A radiation entering the MKID breaks the Cooper pairs in the
    superconducting resonator, and the intensity of the radiation is detected as a
    variation of the resonant condition. Therefore, calibration of the detector
    responsivity, i.e., the variation of the resonant phase with respect to the
    number of Cooper-pair breaks (quasiparticles), is important. We propose a
    method for responsivity calibration. Microwaves used for the detector readout
    locally raise the temperature in each resonator, which increases the number of
    quasiparticles. Since the magnitude of the temperature rise depends on the
    power of readout microwaves, the number of quasiparticles also depends on the
    power of microwaves. By changing the power of the readout microwaves, we
    simultaneously measure the phase difference and lifetime of quasiparticles. We
    calculate the number of quasiparticles from the measured lifetime and by using
    a theoretical formula. This measurement yields a relation between the phase
    response as a function of the number of quasiparticles. We demonstrate this
    responsivity calibration using the MKID maintained at 285mK. We also confirm
    consistency between the results obtained using this method and conventional
    calibration methods in terms of the accuracy.

  • Superconducting Microresonators for Gamma-ray Detection               
    NARUSE Masato; MIYAMOTO Noriaki; TAINO Tohru; MYOREN Hiroaki
    Technical report of IEICE. SCE, Volume:114, Number:247, First page:39, Last page:42, 15 Oct. 2014
    We propose a high spatial resolution gamma ray camera with superconducting resonator arrays for food screening systems. The gamma ray camera is composed of hundreds of microwave resonators. Absorbers are attached to the reverse side of the wafer. The gamma-rays create phonons in the absorber and the resonators detect the phonons propagated from the absorber. As a first step for the proposed camera, we measured 10 lumped element kinetic inductance detectors (LeKIDs) in a 0.3-K sorption cryostat. The event rate of the pixel with the Pb absorber was approximately 5 cps and 6 times higher than that of the pixel without the absorber. The rise and the fall time of events were less than the 1.1 MHz sampling of a vector network analyzer.

    Superconducting nanowire single photon detectors (SNSPDs), those have a low dark count rate characteristics, fast and low jittering response, and high quantum efficiency, are expected to be used in the quantum information field and time-of-flight (TOF) mass spectrometry etc. A readout circuit using superconducting single-flux-quantum (SFQ) logic circuits has been developed to realize fast and low-jittering readout for an array of SNSPDs. SNSPDs with series-parallel meander type configurations have been demonstrated to have photon number resolving capabilities and are expected to be used for an evaluation system of single photon generators and/or an energy-dissolved fast detector for new generation TOF mass spectrometry. In this study, we present design, fabrication and confirmation of correct operations of an SFQ digital readout circuit for an SNSPD with series-parallel meander type configuration.

    We have been developing terahertz cameras using superconducting micro-resonator arrays operated at 4K. A superconducting micro resonator, called Microwave Kinetic Inductance Detector(MKID), is one of the most sensitive detectors for terahertz wave. MKID is made from a Niobium Nitride films whose superconducting transition temperature is 15.7K with the thickness of 150nm. The film is deposited on an MgO substrate by magnetron sputtering method. To increase the number of detectors per area, we estimate the amount of microwave crosstalk between pixels with Ansys Designer. We find that the pixel crosstalk occurs by both inductive and capacitive coupling.

    We propose a novel microwave kinetic inductance detector (MKID) named spiral-MKID typified by a rewound spiral strip structure suitable for terahertz applications. The superconducting rewound strip works as a high-Q half wavelength microwave resonator as well as a broadband terahertz antenna. The spiral-MKIDs fabricated with NbN films reveal loaded quality factors of the order of 104 at 3 K. NbN is one of the promising materials suitable for working on a convenient 4K-refrigerator. We also discuss the expected noise equivalent power of the optimized detector.

    We propose a novel microwave kinetic inductance detectors named Spiral-MKIDs typified by a rewind spiral strip structure suitable for a broad band terahertz detector array application. A superconductng rewind strip works as a high-Q half wave length microwave resonator as well as a broad band antenna for terahertz light. The spiral-MKIDs fabricated with NbN thin films reveals a loaded quality factor of about 250,000 at the maximum. Broad band antenna performance of the spiral strip is confirmed by an almost constant return loss within the frequency range lower than 200GHz to higher than 2THz measured for a 100 times magnified room temperature model fabricated on a cupper foil PCB as well as numerical simulations.

    We successfully fabricated the aluminum based superconducting tunnel junctions (Al-STJs) which used photolithography technique and dry etching process. Since it is not easy to dry etch the aluminum, we cannot form fine electrode pattern like shape of normal distribution function using the conventional reactive etching method. We took the inductively coupled plasma (ICP) on electrical discharge method and enabled dry etch the Al film. We could fabricate the Al-STJs by dry etching method with ICP. We fabricated STJ detectors with the shape of normal distribution function (σ=0.45) and junction sizes of 2,500μm^2 and 10,000μm^2. We measured I-V characteristic at 0.4K and obtained V_g=0.38mV, I_=50nA (junction size of 2,500μm^2).

    We have been fabricated superconducting tunnel junctions (STJs) for photon detector. The STJs were fabricated with three different sizes of normal-distribution-function (NDF) shape junction and five different contact-hole areas. NDF-STJs which has the dispersion parameters of 0.25, 0.15, 0.75 showed good energy resolution with small magnetic field comparing with conventional shaped STJ. The energy resolution of the STJ with different contact areas shows degradation according to increasing of contact area.

    Terahertz radiation is the electromagnetic range between radio waves and light waves. The imaging technology in this range is expected to generate many novel applications such as nondestructive inspection in commercial industries and security systems, medical diagnosis and astronomy. However, detector arrays for terahertz imaging are still under development, and large-scale and high-sensitivity detector arrays are acutely needed in many fields. We have designed, fabricated, and characterized a superconducting detector array using superconducting tunnel junctions (STJs) for terahertz imaging applications. The detector is composed of linearly distributed junctions placed on a superconducting microstrip line and is integrated on two wings of a log-periodic antenna. It is based on the photon-assisted tunneling process. In this paper, we explain the detector outline, performances and future prospects, and demonstrate terahertz imaging using the STJ linear array.

    Diagnosis using terahertz (THz) waves holds a great potential for various applications in fields such as medicine, biology, industry and agriculture because of its transmittance to soft matters as well as the good spatial resolution. In addition, the specific spectral absorption features can be also applicable for identifying materials inside opaque packages. In many such applications, imaging measurements with high sensitivity are required to obtain precisely the distribution of the transmitted THz waves of the measured objects and to distinguish the location of the materials of interest. We are developing two types of THz detectors using Nb-based superconducting tunnel junctions. In this paper, we introduce their detection principles, performances, and recent results including THz imaging.

    We proposed a readout circuit of Superconducting Tunnel Junction (STJ) array detectors. The proposed circuit based on a frequency-division multiplexed readout by applied AC bias current of different frequency to array STJs. An STJ was placed in a balanced bridge circuit, connected a resonance circuit for select output frequency. When photons irradiates to the array STJ, the output signals are frequency multiplexed in an output signal line. We designed a circuit consists of two STJs which output frequencies of 20MHz and 40MHz, respectively. We have successfully confirmed its correct operations using the JSPICE3 superconducting circuit simulator.

    We have proposed and fabricated superconducting tunnel junctions on LiNbO3 and on LiTaO3 substrates for high speed and wide energy band photon detectors working at THz-wave band. The current-voltage characteristics of these STJs were equivalent to conventional STJ, which was fabricated on sapphire substrates. Phonons that produced by irradiating 5.9keV X-ray or THz-wave in the substrates can be detected by the STJ. Comparing the experimental results for three types of STJs, phonons that produced in both LiNbO3 and LiTaO3 substrates have been detected with high absorption efficiency.

    Superconducting Tunnel Junction (STJ) has characteristic of wide band, high speed and high energy resolution as a X-ray detector. In this study, we used STJ with Ta trapping layer. β-Ta has characteristic of small energy gap. It can be expected of high output signal and simple fabrication process. Output signal was 750mV, and energy resolution was 125eV for 5.9keV X-ray at 0.4K.

The characteristic of this STJ on LiNbO_3 was equivalent to conventional STJ, which was fabricated on sapphire substrate. Phonons produced by irradiating 5.9keV X-ray at the surface of LiNbO_3 were detected by the STJ. Comparing spectrum of two STJ, phonons produced in LiNbO_3 substrate showed high energy absorption.

    We have fabricated superconducting tunnel junction (STJ) of Nb/Al/AlO_x/Nb with a superconducting microstrip-coil for X-ray detector. The microstrip-coil was used to apply magnetic field to suppress dc Josephson current of the STJ. The current-voltage characteristics were measured at a temperature ramge from 4.2K to 0.4K. The STJs show V_m value of 7000V with very low leakage current. The STJ was cooled down at 0.4K using ^3He cryostat. 5.9keV X-ray was irradiated into the STJ from a ^<55>Fe. X-ray signal was successfuly detected under the condition of feeding the current into the microstri...

    The superconducting coil integrated on the superconducting tunnel junction(STJ)has been designed and fabricated to suppress the Josephson current for applying an X-ray detector. The I-V characteristics and Fraunhofer characteristics were measured under the magnetic fields of the superconducting coil and an external conventional coil. Characteristic features under the magnetic fields of both coils were quite similar. The suppression of both Josephson current and Fisk step were achieved using the present superconducting coil integrated on the STJ at 4.2K.
