Physical Environment Monitors (PEM) Subgroup
Definition and scope
- PEM is sensing system to check the detector health, noise source and h(t) data quality
Selection, installation and maintenance of PEMs in KAGRA detector are the main tasks so that the data necessary for commissioning procedure are collected.
