Upgrades to the TEXTOR electron cyclotron emission imaging diagnostic

A 128 channel electron cyclotron emission imaging instrument has been routinely used to study magnetohydrodynamics physics such as m=1 and m=2 modes on the TEXTOR tokamak. As currently configured, each of the 16 mixer array elements measures plasma emission at 8 simultaneous frequencies to form a 16x8 image of electron temperature profiles and fluctuations over an area of 16 cm (vertical) by 6 cm (horizontal). A redesigned mixer array, coupled with new wideband electronics to be installed later this year, will increase the plasma coverage to 17 cm(v)x9 cm(h). The new arrangement offers increased temperature resolution together with new gain and video bandwidth controls in a highly modular configuration for ease of maintenance and facilitation of future upgrades both in frequency coverage as well as number of channels.
