  2. USED ANTENNA MODEL 2 JUNCTION MODULE number of active waveguides per module = 4 number of passive waveguides per module = 4

  3. 2 JUN.MODULE PHASING

  4. USED ANTENNA MODEL 3 JUNCTION MODULE number of active waveguides per module = 8 number of passive waveguides per module =8 phasing as DDD2001

  5. 3 JUN.MODULE PHASINGNEXT SLIDE

  6. WAVEGUIDE DIMENSIONS 3 junction(2 junction) module active = 58mm x 9.25mm(10mm) passive = 58mm x 7.25mm (8mm) wall = 3mm passive waveguide depth = 17.50mm

  7. PARAMETERS • Btor = 5.3 tesla • frequency = 5 GHz • phase between PAM modules = 0 • magnetic field tilt angle = 0

  8. PLASMA DENSITY PROFILES _2 => linear with length = 2mm _20 => linear with length = 20mm
