An accelerator experiment for junior and senior high school students to improve students' involvement in fundamental physics
K. S. Tanaka, K. Harada, T. Hayamizu +7
In Japan, research activities by junior and senior high school students show an upward trend. However, there are limited examples of research activities in the field of elementary…
Two-dimensional beam profile monitor for the detection of alpha-emitting radioactive isotope beam
K. S. Tanaka, U. Dammalapati, K. Harada +7
Ions with similar charge-to-mass ratios cannot be separated from existing beam profile monitors (BPMs) in nuclear facilities in which low-energy radioactive ions are produced due t…
Systematic studies of rubidium-exposed surfaces by X-ray photoelectron spectroscopy and light-induced atom desorption
Atsushi Hatakeyama, Sae Watashima, Ayumi Yamaguchi +6
We systematically investigated various types of surfaces on which rubidium (Rb) atoms were deposited by X-ray photoelectron spectroscopy (XPS) and measured the light-induced atom d…
Thermal surface neutralization of Fr ions with metal foils for magneto-optical trapping of radioisotopes
H. Kawamura, T. Aoki, K. Harada +7
We investigate neutralization processes (especially thermal surface neutralization), which are required for the magneto-optical trapping of radioactive atoms. A variety of neutrali…
Alkali ion-to-neutral atom converter for the magneto-optical trap of a radioactive isotope
Hirokazu Kawamura, Ken-ichi Harada, Tomoya Sato +12
We have developed a unique neutralizer device that uses an yttrium target surrounded by a platinum wall to magneto-optically trap radioactive atoms. In general, the radioactive nuc…
Laser frequency locking with 46 GHz offset using an electro-optic modulator for magneto-optical trapping of francium atoms
K. Harada, T. Aoki, S. Ezure +21
We demonstrated a frequency offset locking between two laser sources using a waveguide-type electro-optic modulator (EOM) with 10th-order sidebands for magneto-optical trapping of…
