Search for hidden-photon cold dark matter using a K-band cryogenic receiver
Nozomu Tomita, Shugo Oguri, Yoshizumi Inoue +4
We search for hidden-photon cold dark matter (HP-CDM) using a spectroscopic system in a K-band frequency range. Our system comprises a planar metal plate and cryogenic receiver. Th…
Hidden photon CDM search at Tokyo
Jun'ya Suzuki, Yoshizumi Inoue, Tomoki Horie +1
We report on a search for hidden photon cold dark matter (HP CDM) using a novel technique with a dish antenna. We constructed two independent apparatus: one is aiming at the detect…
Experimental Search for Hidden Photon CDM in the eV mass range with a Dish Antenna
J. Suzuki, T. Horie, Y. Inoue +1
A search for hidden photon cold dark matter (HP CDM) using a new technique with a dish antenna is reported. From the result of the measurement, we found no evidence for the existen…
Search for Hidden photons with Sumico
Yoshizumi Inoue, Tetsuya Mizumoto, Ryosuke Ohta +3
We searched for solar hidden photons in the visible photon energy range using a hidden photon detector add-on attached to Sumico. It consists of a parabolic mirror of dia. 0.5m and…
First Results from Dark Matter Search Experiment in the Nokogiriyama Underground Cell
W. Ootani, M. Minowa, K. Miuchi +5
An experiment to search for hypothetical particle dark matter using cryogenic thermal detector, or bolometer is ongoing. The bolometer consists of eight pieces of 21 g LiF absorber…
The Tokyo Axion Helioscope Experiment
Makoto Minowa, Shigetaka Moriyama, Yoshizumi Inoue +3
A preliminary result of the solar axion search experiment at the University of Tokyo is presented. We searched for axions which could be produced in the solar core by exploiting th…
Direct search for solar axions by using strong magnetic field and X-ray detectors
Shigetaka Moriyama, Makoto Minowa, Toshio Namba +3
We have searched for axions which could be produced in the solar core by exploiting their conversion to X rays in a strong laboratory magnetic field. The signature of the solar axi…
First Results of Tokyo Dark Matter Search with a Lithium Fluoride Bolometer
Wataru Ootani, Makoto Minowa, Takayuki Watanabe +5
The First results of the Tokyo dark matter search programme using a 21-g lithium fluoride bolometer are presented. The background spectrum was measured in the surface laboratory. W…
Sensitive germanium thermistors for cryogenic thermal detector of Tokyo dark matter search programme
Wataru Ootani, Yutaka Ito, Keiji Nishigaki +3
Sensitive n-type and p-type germanium thermistors were fabricated by the melt doping technique and by the neutron transmutation doping (NTD) technique, respectively, aiming at a us…
A liquid-helium cooled large-area silicon PIN photodiode x-ray detector
Yoshizumi Inoue, Shigetaka Moriyama, Hideyuki Hara +2
An x-ray detector using a liquid-helium cooled large-area silicon PIN photodiode has been developed along with a tailor-made charge sensitive preamplifier whose first-stage JFET ha…
