1)The physical dimensions of the plasma
2)The strength and fluctuations of the BΦ& Bθ fields.
● We found:
1) Plasma diameter ~ 4 cm.
2) The magnetic field oscillations rotate clockwise with velocities of 200-1000 krad.s-1
3) there are strong magnetic oscillations in the
plasma with an inverse relationship
between angular velocities and the
amplitude of the oscillations.
