Fusion power production from TFTR plasmas fueled with deuterium and tritium

摘要

Peak fusion power production of 6.2 (plus minus) 0.4 MW has been achieved in TFTR plasmas heated by deuterium and tritium neutral beams at a total power of 29.5 MW. These plasmas have an inferred central fusion alpha particle density of 1.2 (times) 10(sup 17) m(sup (minus)3) without the appearance of either disruptive MHD events or detectable changes in Alfven wave activity. The measured loss rate of energetic alpha particles agreed with the approximately 5% losses expected from alpha particles which are born on unconfined orbits.
