Tr. Robinson et al., O-MODE AND X-MODE HEATING EFFECTS OBSERVED SIMULTANEOUSLY WITH THE CUTLASS AND EISCAT RADARS AND LOW-POWER HF DIAGNOSTICS AT TROMSO, Annales geophysicae, 15(1), 1997, pp. 134-136
Results are presented from the first RF heating campaign at Tromso in
which the new CUTLASS HF radar, together with the EISCAT UHF radar and
a low power HF diagnostic radio system were in simultaneous operation
. Observations during an RF heating sequence, when ordinary and extrao
rdinary heater polarisations were used alternately provided informatio
n concerning heater small scale field aligned plasma irregularity exci
tation, anomalous heating and anomalous absorption effects, simultaneo
usly, for the first time. These results provide unambiguous observatio
nal evidence for the important role played by plasma irregularities in
anomalous transport processes, induced during RF heating.
