Experimeuts were done in order to know interactions between high density hydrogen plasmas and magnetic fields. (cusped field, single coil field and mirror field)
Behaviors of injected plasma were studied usuig streak photographs taken through a long slit imaged at the axis of the straight vacuum vessel.
Experimental results are as follows.
1) Single coil field
Plasma decreases its axial velocity in encountering strong field, and penetrates through it even when the field strenght is more than 8, 000 gauss.
2) Cusped field
After penetrating through the entrance cusp, plasma takes back its original speed and goes through the zero region of the field with this constant velocity up to a certain point where the velocity changes abruptly.
After then plasma moves toward the exit cusp and is reftected by a 6000-gauss field.
3) Mirror field
Plasma injected into mirror field is not trapped.
