Claim 1
Independent Claim
207 words
A SYSTEM FOR PULSING A BEAM OF IONIZED PARTICLES, COMPRISING A COLLECTOR HAVING A SLIT APERTURE THEREIN DISPOSED WITH ITS CENTER IN ALIGNMENT WIHT THE AXIS OF BEAM TRAVERSE OF AN IONIZED PARTICLE BEAM, BIAS FIELD MEANS GENERATING A CONTINUOUS BIAS FIELD FOR DEFLECTING SAID BEAM TRANSVERSELY OFF AXIS RELATIVE TO SAID SLIT APERTURE, MEANS PERIODICALLY GENERATING A PULSED SWEEP DEFLECTION FIELD IN OPPOSITION TO SAID BIAS FIELD WITH THE STRENGTH OF SAID DEFLECTION FIELD WIHT RESPECT TO TIME HAVING A TRAPEZOIDAL WAVEFORM INCLUDING A SUBSTANTIALLY LINEAR VERY FAST RISE TIME LEADING EDGE AND EAXPONENTIAL TRAILING EDGE OF RELATIVELY LONG DECAY PERIOD INTERCONNECTED BY A CONSTANT FLAT CREST PORTION, AND MEANS PERIODICALLY GENERATING A SECOND PULSED SWEEP DEFLECTION FIELD ORIENTED 90* TO SAID FIRST DEFLECTION FIELD AND DELAYED RELATIVE THERETO BY A TIME AT LEAST AS LONG AS THE RISE TIME OF A PULSE OF THE FIRST FIELD AND SHORTER THAN THE TIME BETWEEN INITIATION OF THE LEADING EDGE AND TRAILING EDGE THEREOF, SAID SECOND PULSED FIELD HAVING PULSES OF CONTANT PEAK MAGNITUDE SUFFICIENT TO DEFLECT SAID BEAM PARALLEL TO SAID SLIT APERTURE BEYOND AN END THEREOF AND PREVENT SAID BEAM FROM CROSSING SAID SLIT APERTURE DURING DECAY PERIODS OF THE PULSE OF SAID FIRST DEFLECTION FIELD.
