TI - Multi-channel retarding field analyzer for EAST JO - Plasma science & technology VL - 20 IS - 5 SN - 1009-0630 CY - Bristol PB - IOP M1 - FZJ-2019-06023 SP - 054001 - PY - 2018 AB - A multi-channel retarding field analyzer (MC-RFA) including two RFA modules and two Langmuir probes to measure the ion and electron temperature profiles within the scrape-off layer was developed for investigations of the interplay between magnetic topology and plasma transport at the plasma boundary. The MC-RFA probe for the stellarator W7-X and first measurements at the tokamak EAST was designed. The probe head allows simultaneous multi-channel ion temperature as well as for electron temperature measurements. The usability for radial correlation measurements of the measured ion currents is also given.
