“…Much faster response time is desired for counting high-intensity neutron beam for more effective use of neutrons. We developed a superconducting detector for sensing neutrons with high-spatial resolution and fast response time, and first succeeded in detecting the neutrons using an MgB2 thin film in our preceding works [4][5][6]. We also developed a superconducting neutron detector using a Nb-based current-biased kinetic inductance detector (CB-KID) with a 10 B conversion layer [7][8][9][10].…”

Abstract. In our preceding works, we demonstrated successful neutron detection using a superconducting current-biased kinetic inductance detector (CB-KID), which is composed of two Nb-based superconducting meanderlines and the 10 B neutron absorption layer. The CB-KID with a 10 B absorption layer outputs the voltage pulses when it is irradiated by pulsed neutrons. We expected that the voltage V is proportional to a product of the bias current Ib and a time derivative of the local kinetic inductance dΔLk/dt, and a pair of signals propagate along the Nb stripline as an electromagnetic wave at a certain fraction of the light velocity c toward end electrodes. It still remains to be revealed why the signal voltage shows such a continuum in the histogram of the signal height even if the incident energy of the light ion is apparently monochromatic. In the present work, we investigated the distribution of the height and width of the signal. We found a clear correlation between height and width, which might be a key of understanding the operating principle of our detector. We consider that the origin of the signal distribution is due to the positional dependence of the light ion bombardment with respect to the meandering Nb nanowire.

In all the simulations, we applied triangular input to simulate inductive mode of operation, similar to the measurement results of [6], and square input to simulate the resistive mode of operation similar to the optical source that we use in our experiments, 1550 nm wavelength laser with 1 ns rise/fall times and 5ns duration time. inductance of the stripline as 10 nH and changed the series resistance R from 1 Ω to 50 Ω.…”

“…(1). This behavior is previously investigated and named as current biased kinetic inductance detector (CB-KID) [6]. If the SSLD is biased close to the critical current of the stripline, then an incoming radiation causes part of SSLD switch to the normal state and change of resistance translates to a voltage signal under constant bias current with a relation shown in Eq.…”

SUMMARYOne of the fundamental problems in many-pixel detectors implemented in cryogenics environments is the number of bias and read-out wires. If one targets a megapixel range detector, number of wires should be significantly reduced. One possibility is that the detectors are serially connected and biased by using only one line and read-out is accomplished by on-chip circuitry. In addition to the number of pixels, the detectors should have fast response times, low dead times, high sensitivities, low inter-pixel crosstalk and ability to respond to simultaneous irradiations to individual pixels for practical purposes. We have developed an equivalent circuit model for a serially connected superconducting strip line detector (SSLD) array together with the read-out electronics. In the model we take into account the capacitive effects due to the ground plane under the detector, effects of the shunt resistors fabricated under the SSLD layer, low pass filters placed between the individual pixels that enable individual operation of each pixel and series resistors that prevents the DC bias current flowing to the read-out electronics as well as adjust the time constants of the inductive SSLD loop. We explain the results of investigation of the following parameters: Crosstalk between the neighbor pixels, response to simultaneous irradiation, dead times, L/R time constants, low pass filters, and integration with the SFQ front-end circuit. Based on the simulation results, we show that SSLDs are promising devices for detecting a wide range of incident radiation such as neurons, X-rays and THz waves in many-pixel configurations.

We proposed a current‐biased kinetic inductance detector (CB‐KID) as a novel superconducting detector to construct a neutron transmission imager. The characteristics of a superconducting neutron detector have been systematically studied to improve a spatial resolution down to 10 in transmission imaging. In this study, we report the application of the energy‐resolving neutron imaging to investigate major components of materials by analyzing neutron transmission spectra from 1 meV to 500 keV. We succeeded in identifying that copper (Cu) and iron (Fe) are major components respectively in commercial nuts and screws as test samples with the aid of Rietveld imaging of transmission spectra (RITS) program in analyzing transmission spectra in longer wavelengths. The Ti screw was also confirmed by comparing the nuclear resonance absorption measurements and simulations in high‐energy regions. We demonstrated that our superconducting neutron detector is applicable to reveal the transmission spectra in the wide range from cold‐neutron energies to higher neutron energies even up to 500 keV. By selecting distinctive energy regions of pulsed neutrons, we succeeded in mapping the distribution of SmSn3 compound using the strong neutron absorption in samarium (Sm) and the selective nuclear‐resonance dips in Sm. By taking advantage of using CB‐KID in conducting neutron imaging, the CB‐KID method is extensively useful for various purposes in material sciences through energy‐selective neutron spectroscopy from 1 meV to 500 keV. © 2024 Institute of Electrical Engineers of Japan and Wiley Periodicals LLC.
