Design of neutral beam injection system for KSTAR tokamak
چکیده انگلیسی

The neutral beam injection (NBI-1) system has been designed for providing a 300 s deuterium beam of 120 kV/65 A as an auxiliary heating and current drive system of the KSTAR (Korea Superconducting Tokamak Advanced Research) tokamak. The deuterium beam is produced from a long pulse ion source composed of a bucket-type plasma generator and a multi-aperture tetrode accelerator with the help of discharge power supplies and high voltage (HV) power supplies. The beamline components (BLCs) include a neutralizer with an optical multi-channel analyzer (OMA) section, a bending magnet (BM), an ion dump assembly, a movable calorimeter, beam scrapers, and a cryo-sorption pump system in a rectangular vacuum tank. A beam duct equipped with bellows and a voltage break is placed between the NBI vacuum tank and the KSTAR vacuum vessel. All data and parameters of the NBI system are controlled by a control and data acquisition (CODAQ) system through the EPICS based Ethernet interface.

Research highlights▶ Describe the design and specifications of the first KSTAR neutral beam injector. ▶ Describe the detailed design basis for the first operational beam system to operate at the high power levels for a long pulse of 300 s. ▶ Describe the important beamline structures and design requirements of the KSTAR NBI system for a long pulse operation of 300 s.
