摘要：

Instrumentation has been developed for the measurement of electron temperature and density profiles at the boundary of COMPASS-D tokamak plasmas from He I line intensities. The technique is applicable to measurements of n(e) and T-e over the relevant ranges of 10(17) - 10(20) m(-3) and 10-500 eV. Spectra from eight viewing chords viewing a thermal helium jet are recorded on a CCD sensor with approximate to 1 ms time resolution. A 0.6 m Czerny-Turner spectrometer, corrected for astigmatism using an internal, cylindrical lens optimizes throughput by availing of a 110 x 110 mm(2), 300 l/mm grating. n(e) and T-e profile measurements from L-mode (low) and quiescent H-mode (high) confinement plasmas are presented.
