A way to reduce plasma spin-up in fiel-revesed configurations

  • 1. Comision Nacional de Energia Atomica, Bueno Aires (Argentina). Div. de Fusion Nuclear

Description

Supposing that the plasma spin-up experimentally observed in field-reversed configurations is due to particle losses with preferentially oriented canonical angular momentum, it is shown that the introduction of magnetic divertors on the separatrix should strongly reduce the torque on the confined plasma. Plasma diffusion should be concentrated at the divertors and so particles could leave the closed magnetic field line region without preferentially oriented canonical angular momentum. This implies that the plasma spin-up should be lower than in the absence of divertors. (author)

Abstract (Portuguese)

Supondo que o 'spin-up' do plasma observado experimentalmente em configuracoes revertidas de campo e devido a perda de particulas com momento angular canonico preferencialmente orientado, mostra-se que a introducao de um desviador magnetico sobre a separatriz deve reduzir fortemente o torque do plasma confinado. A difusao do plasma deve estar concentrada nos desviadores e entao as particulas poderiam deixar a regiao da linha de campo magnetico fechado sem momento angular canonico preferencialmente orientado. Isto implica que o 'spin-up' do plasma deve ser menor do que na ausencia de desviadores. (M.C.K.)
