Abstract

THIS STUDY OF TRANSVERSE MAGNETIC FIELD PENETRATION THROUGH THE JET MAGNETIC FIELD COIL SYSTEMS AND SUPPORTING STRUCTURES WAS DONE DURING THE INITIAL JET DESIGN PHASE (1973-78). IT WAS PART OF A MAJOR RADIUS COMPRESSION PLASMA HEATING FEASIBILITY STUDY. IT FIRST APPEARED IN 1977 AS INTERNAL REPORT JTN/B(77)90 AND IS NOW ISSUED UNCHANGED EXCEPT FOR BETTER ESTIMATES OF THE PENETRATION TIMES. THE MAGNETIC FIELD PENETRATION CAN BE CHARACTERISED BY THE EVOLUTION OF THE AVERAGE TRANSVERSE MAGNETIC FIELD INSIDE THE TORUS WHEN A CONSTANT TRANSVERSE FIELD IS APPLIED. THE INTERACTION OF THE EDDY CURRENTS WITH THE PLASMA AND THE POLOIDAL FIELD COILS AND IRON CIRCUIT EFFECTS ARE IGNORED. THE ESTIMATED RISE-TIME CAN BE CONSIDERED ONLY AS INDICATIVE FOR THE LOWER LIMIT OF THE ADIABATIC COMPRESSION TIME WHICH MAY BE ACHIEVED IN JET.
