Scientific Highlights since 1993

Several new discoveries have been made in the field of HF-interactions
since the transfer of the facility from the Max-Planck Institute to
EISCAT in 1993. They are in diverse areas such as E-region heating or
cooling, Pc-1 micropulsation generation, the effect of enhanced electron
temperature on VHF radar Polar Mesospheric Summer Echoes,
Artificial Periodic Irregularities, HF-induced airglow,
electron heating in the F-region, and magnetic-field-aligned
effects in Langmuir turbulence as well as electron heating. Our
knowledge in other areas, such as ELF/VLF wave generation, SEE
emissions, and the generation of striations, has also improved.
Many of these new results come from the application of new or refined
measurement techniques.
