First electron temperature edge measurements on the ASDEX upgrade tokamak using a heterodyne radiometer
Description
The design of a multi-channel heterodyne radiometer used to determine the electron temperature in the edge region of the ASDEX Upgrade (AUG) tokamak plasma by measuring the microwave electron cyclotron emission (ECE) is described. A novel feature of the system is the use of both side-bands of a heterodyne mixer to maximise the available radiation bandwidth. First measurements of the temperature profile in the edge region during the development of the H-mode plasmas and marfes are presented and discussed. 11 refs., 8 figs., 1 tab
