First observation of gravitational waves by LIGO detectors was done. This historical achivement was possible because of the ultimate sencing technology of small displacement by laser interferometers, theoretical understanding of gravitational wave signals, and the data analysis technology to extract tiny signal buried in noise. In this article, we review data analysis technology used in the observation of gravitational waves.
Particle accelerators and physics experiments have been advanced with essential contribution of superconducting magnet and radio-frequency (RF) technologies. They have been key technologies for opening up unprecedented windows for the energy and intensity frontiers in particle accelerators and physics experiments. This report reviews the progress in these technologies and discusses their future prospects.
