摘要
The successful operation of a popup Langmuir probe system, which was installed in the JET MkIIa divertor, is described. The system utilises the ambient magnetic field in tokamak plasmas to act on a current carrying coil and pop up a rail containing Langmuir probes. Measurements were made using pin-plate probes which, owing to their relatively large exposed area, are ideally suited for use with such a system. Details of the design, testing, measurements and potential applications of JET's popup system are given. (C) 1999 The JET Joint Undertaking. Published by Elsevier Science S.A. All rights reserved.
