Status report of the Tokyo axion helioscope experiment
Y. Inoue, M. Minowa, Y. Akimoto +3
We have searched for solar axions with a detector which consists of a 4T x 2.3m superconducting magnet, PIN-photodiode X-ray detectors, and an altazimuth mount to track the sun. Th…
Search for solar axions with mass around 1 eV using coherent conversion of axions into photons
Y. Inoue, Y. Akimoto, R. Ohta +3
A search for solar axions has been performed using an axion helioscope which is equipped with a 2.3m-long 4T superconducting magnet, a gas container to hold dispersion-matching gas…
Dark matter search experiment with CaF2(Eu) scintillator at Kamioka Observatory
Y. Shimizu, M. Minowa, W. Suganuma +1
We report recent results of a WIMP dark matter search experiment using 310g of CaF2(Eu) scintillator at Kamioka Observatory. We chose a highly radio-pure crystal, PMTs and radiatio…
Dark Matter Search with Direction Sensitive Scintillators
H. Sekiya, M. Mionwa, Y. Shimizu +2
We have carried out the dark matter search with a 116g direction-sensitive stilbene crystal in Kamioka Observatory. With the crystal fixed to the earth, we searched the modulation…
Dark Matter Search with Direction Sensitive Scintillator
H. Sekiya, M. Minowa, Y. Shimizu +2
A direction sensitive dark matter detector using organic crystals is being developed. It exploits the anisotropic scintillation efficiency of organic crystals with respect to the d…
Measurements of anisotropic scintillation efficiency for carbon recoils in a stilbene crystal for dark matter detection
H. Sekiya, M. Minowa, Y. Shimizu +2
It is known that scintillation efficiency of organic single crystals depends on the direction of nuclear recoils relative to crystallographic axes. This property could be applied t…
Directional scintillation detector for the detection of the wind of WIMPs
Y. Shimizu, M. Minowa, H. Sekiya +1
The quenching factor of the proton recoil in the stilbene scintillator was measured with a 252Cf neutron source and was found to be 0.1 - 0.17 in the recoil energy range between 30…
Search for sub-electronvolt solar axions using coherent conversion of axions into photons in magnetic field and gas helium
Y. Inoue, T. Namba, S. Moriyama +4
A search for solar axions has been performed using an axion helioscope which is equipped with a 2.3m-long 4T superconducting magnet, PIN-photodiode X-ray detectors, and a telescope…
An x-ray detector using PIN photodiodes for the axion helioscope
T. Namba, Y. Inoue, S. Moriyama +1
An x-ray detector for a solar axion search was developed. The detector is operated at 60K in a cryostat of a superconducting magnet. Special care was paid to microphonic noise immu…
Recent results from the Tokyo axion helioscope experiment
Y. Inoue, T. Namba, S. Moriyama +4
We have searched for axions which could have been produced in the solar core using an axion helioscope with a 2.3m-long 4T superconducting magnet. Axion mass region up to m_a=0.26e…
