Abstract

In order to reach the full performance plasma parameters of ASDEX Upgrade as provided by the machine technique a heating power of 12 to 15 MW is required. For the minimum required power the appropriate choices for the basic heating system are 6 MW ICRH and 6 MW neutral injection, both with a long pulse capability of up to 10 seconds. ICRH in a frequency range of 30 to 120 MHz shall cover minority, hydrogen fundamental and 2nd harmonic and deuterium 2nd harmonic heating. For neutral injection four JET sources with 60 keV H degrees and 80 A combined in one injection box were chosen. The averaged injection angle is 24 degrees to perpendicular at R-o = 1.7 m. Both systems shall be installed during 1988. The costs are 57.4 MDM for both. Also mentioned in this application are the plans for the longer range future concerning LH current drive, ECRH and Alfven wave heating. But these possible extensions are not the object of this application.
