LOW PRESSURE RING-DISCHARGE IN AN EXTERNAL MAGNETIC FIELD
Technical Report
·
OSTI ID:4258575
A ring-discharge at pressures below 10/sup -3/ mm Hg is described. The discharge is produced in a cold-cathode tube whose electrode-structure resembles a Penning gauge. It is shown that by placing this tube inside a ring-shaped magnetic flux-tube the latter can be filled with plasma generated in the cold cathode discharge. The plasma density, the expansion speed of the plasma fluid, and its drift across the magnetic field are measured by two independent methods and it is shown that the results are in an order of magnitude agreement with the one-fluid description of low density plasma, (auth)
