| 研究実績の概要 |
In FY2021, we have rebuilt the experimental apparatus for laser cooling due to the re-location of the laboratory. After relocation of laboratory, we have first reconstructed the UHV system and achieved a pressure of 10^-9 mbar. We have also established the laser-locking and optical setup for cooling and repumping lasers. We have built the double-pass AOM system required for polarization gradient cooling. We have also constructed the optical setup for magneto-optical trap. Finally we have succeeded in achieving the magneto-optical trap in the new laboratory.
Also, we have established the experimental apparatus for fabrication of nanofibers under a newly built clean booth facility.

現在までの達成度 (区分)
3: やや遅れている
理由
The reason for the delay is the relocation of the laboratory. We have to re-establish various apparatus and experimental setups required for the experiments.
We are still far from the final goal. But the short-term goals are achieved as expected.

| 今後の研究の推進方策 |
The implementation plans for FY2022 are the followings.
Development of software controlled multitone RF-signal generation. Development of optical setup for creating an array of tweezers using AOMs driven by multitone RF-signal and detection of array of single atoms using EMCCD camera. Installation of high quality 300 nm diameter nanofiber into UHV chamber. Trapping and imaging array of single atoms on nanofiber.
Preliminary experiments on emission properties of array of single atoms on nanofiber.
