title: Access-control and interlock-signal systems for the LHD experimental hall.
abstract: An access-control system has been developed and installed at the National Institute for Fusion Science. The system uses an interlock-signal system and a group-access-control system to safeguard the operation of the large helical device. In this paper, the access-control system is described along with its features, advantages and disadvantages, and benefits.
