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…

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…

Short-range test of the universality of gravitational constant at the millimeter scale using a digital image sensor

K. Ninomiya, T. Akiyama, M. Hata +19

The composition dependence of gravitational constant is measured at the millimeter scale to test the weak equivalence principle, which may be violated at short range through ne…

A new measurement of electron transverse polarization in polarized nuclear beta decay

H. Kawamura, T. Akiyama, M. Hata +20

The Mott polarimetry for T -Violation (MTV) experiment tests time-reversal symmetry in polarized nuclear beta decay by measuring an electron's transverse polarization as a form of…

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…
