Development of 'Popup' Langmuir Probe System for the JET MkIIa Divertor
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 theitr relatively large exposed area, are ideally suited for use with such a system. Details of the design, testing, measurements and potential applications of the JET's 'pop-up' system are given.
