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.
