| Research Abstract |
We have constructed a helium cryostat with a collision chamber in which molecules are cooled through collisions with cold He gas, and we have confirmed signals from cold molecules laser-ablated from a solid sample. We have constructed quadrupole Stark molecular selector and demonstrated that the cold ND_3 molecules about a couple of Kelvin are selected and guided from ND_3 gas at room temperature. We have constructed a superconductive microwave resonator with a Q-factor of 3x10^5. With these results our research is promising for the realization of cooling and trapping of molecules by use of microwave.
