| Research Abstract |
We have developed new method to decrease time for cooling mirror suspension systems of laser interferometric gravitational wave(GW) detectors. The key point of the method is heat transferring using high efficiency radiation. If the method will be applied to the laser interferometric GW detector KAGRA which is constructing in Kamioka mine, the cooling time could be decreased to 28 days from 50 days.
