研究開始時の研究の概要

We aim at realizing a sub-micrometer resolution with a novel 8ch current-biased kinetic inductance detector (CB-KID). We improve the CB-KID readout circuit to resolve timestamps at 30ps clock to enhance a spatial resolution. We plan to realize various fruitful applications.

研究実績の概要

This project aims to develop sub-micrometer resolution neutron image with a novel 8 channels current-biased kinetic inductance detector (CB-KID) system. In fiscal 2023, we succeeded in stabilizing an operating temperature at 5K ±70uK. This improved a spatial resolution of neutron transmission image down to 10um when the sample was installed at low temperature and it was 24um when the sample was placed at room temperature [1,2]. This also reduces a difference of spatial resolution between central region and surrounding region in the detector. A temporal resolution of time-to-digital convertor (TDC) strongly influences to a spatial-resolution neutron image in the delay-line CB-KID. We built a new TDC system named as Kalliope-II. A temporal resolution was estimated withing +/-150ps. This is much better than the previous readout circuit (named as Kalliope-I). Data acquisition (DAQ) program and data analysis program were updated to deal with new system. A quasi-on-line monitor imaging becomes possible during imaging experiments. The 8ch CB-KID is under development. We plan to proceed the experiments in the next fiscal year.

理由

Neutron transmission imaging by using CB-KID showed the resolution of 10um. This is one of the best in using the counting type neutron detector. We developed the new 30ps readout circuit to extract the best performance of the CB-KID system. The DAQ program became possible to give a quasi-online image monitoring. This is in good accordance with our plan.
We suppose that our project has been processed rather smoothly.

今後の研究の推進方策

In fiscal 2024, (1) we will continue to optimize the new Kalliope-II readout circuit including firmware update of the Kalliope-II readout circuit. (2) We plan to compare the results of 30-ps Kalliope-II measurements and the results of 1000-ps Kalliope-I measurements by doing simultaneous measurements for mutual comparisons. (3) We start the testing of the 8ch CB-KID detector using the Kalliope-II circuit. (4) Measurement and analysis programs will be updated to deal with the 8ch CB-KID data. (5) The 8 channels neutron detectors will be screened systematically by low temperature experiments using liquid helium and low-temperature probe designed for the CB-KID detectors. This can be done without neutron beams. (6) The standard Gd Siemens-star sample will be tested either at low temperature or at room temperature to achieve the best resolution. We summarize the project.
