Particle-confining devices having magnetic mirrors

Claim 1

A PLASMA CONFINEMENT DEVICE COMPRISING AN ELONGATED EVACUATED VESSEL INCLUDING TWO CYLINDERS EFFECTIVELY COMMUNICATING WITH EACH OTHER THROUGH A BODY ELECTRICALLY FORMING A RESONANT CIRCUIT AT A PREDETERMINED ULTRAHIGH FREQUENCY, MEANS FOR SEPARATELY INJECTING INTO SAID VESSEL IONS AND ELECTRONS CONSTITUENTS OF SAID PLASMA, MEANS FOR PRODUCING IN SAID VESSEL A SUBSTANTIALLY LONGITUDINAL, TIME-CONSTANT MAGNETIC FIELD WHOSE INTENSITY INCREASES FROM A MINIMUM ESSENTIALLY AT THE MIDDLE OF THE VESSEL TO A MAXIMUM VALUE NEAR THE ENDS THEREOF, AND MEANS FOR PRODUCING IN SAID CIRCUIT ULTRA-HIGH FREQUENCY ELECTROMAGNETIC OSCILLATIONS OF SUBSTANTIALLY SAID PREDETERMINED FREQUENCY, THE SAID MINIMUM MAGNETIC FIELD INTENSITY BEING SO INTERRELATED WITH THE CHARGE AND THE MASS OF DESIRED PARTICLES WITHIN SAID PLASMA THAT THE CYCLOTRON RESONANCE FREQUENCY OF SAID PARTICLES IS SUBSTANTIALLY EQUAL TO SAID PREDETERMINED FREQUENCY.
