“…Specifically, a micropattern gaseous detector (MPGD) represented by a gas electron multiplier (GEM) [7,8] is termed as a two-dimensional gas detector. A typical GEM-based detector possesses a position resolution approximately of 1 mm [5]. However, practical use of the detector is inconvenient because it is necessary to maintain the flow of fresh gas to ensure that the gas is fresh.…”

“…There is an increasing demand for improved spatial resolution and temporal resolution of the detectors used for these measurements. Examples of two-dimensional detectors include imaging plates [2], scintillators [3], two-dimensional gas detectors [4,5], and fluorescence imaging [6]. Among the aforementioned detectors, the two-dimensional gas detector displays excellent characteristics in terms of spatial and temporal resolution.…”

A capillary plate (CP) gas detector is a type of a hole-type micropattern gaseous detector. The detector displays high spatial resolution characteristics in two-dimensional radiation detection by using a CP with a small channel pitch. In this study, a sealed-type CP gas detector for neutron imaging was developed. The detector converts the incident position of neutrons to an optical image. A novel imaging system was constructed, and it comprised the CP gas detector, an image intensifier unit, and a science-CMOS camera. The system was tested with a compact accelerator driven neutron source, "KUANS." Each signal of charged particles generated by a nuclear reaction between a neutron and a 10 B layer was obtained. The results indicated that neutron images were obtained clearly.

“…However, spatial resolution is still not satisfactory enough to satisfy various needs. It typically remains on the submillimetre scale with the use of conventional neutron detectors such as a miniaturized gas counter [3] although it becomes on the scale of several tens µm in high-end neutron detectors such as a detector using a micro channel plate and optical readout [4]. Much faster response time is desired for counting high-intensity neutron beam for more effective use of neutrons.…”

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.

“…2,3 GEM detectors are now utilised in varied scientific research, including tracking devices in nuclear and particle physics, medical imaging, astronomy and neutron detection. [4][5][6][7] The 10 cm × 10 cm GEM detector was designed, developed and supplied by the Gas Detectors Development Group at the European Organization for Nuclear Research (CERN). The triple GEM detector consists of three GEM foils, which are 50 µm thick insulating foils made of polyimide (Kapton).…”
