PEM Injection Tests with KAGRA Mode Cleaner
Introduction
PEM (Physical and Environmental Monitor) injection is a way to identify environmental noise sources by intentionally injecting them, such as vibrations, large sound or electromagnetic waves. We would like to test the latest PEM injection techniques in KAGRA. The only interferometric apparatus working in KAGRA at the time of the workshop will be the mode cleaner (MC). Therefore, we will use the MC as a testbed for the PEM injection.
