Claim 1
Independent Claim
169 words
AN ACCELEROMETER COMPRISING; A DRIFT TUBE FOR ENCLOSING A STREAM OF ELECTRONS, A CATHODE GUN POSITIONED AT ONE END OF THE DRIFT TUBE FOR GENERATING A FOCUSED BEAM OF ELECTRONS; VELOCITY MODULATION MEANS FOR SEPARATING THE ELECTORNS STREAM INTO DISCRETE GROUPS, AN ANODE MOUNTED AT THE OTHER END OF THE DRIFT TUBE FOR COLLECTING THE ELECTRON GROUPS AND TRANSFERRING THEM INTO ELECTRICAL PULSES, HIGH FREQUENCY GENERATING MEANS FOR APPLYING HIGH FREQUENCY POWER TO SAID VELOCITY MODULATION MEANS TO CONTROL THE MODULATION FREQUENCY, SAID GENERATING MEANS ALSO COUPLED TO SAID ANODE, A WINDING SURROUNDING THE DRIFT TUBE FOR GENERATING A MAGNETIC FIELD IN AXIAL ALIGNMENT WITH THE AXIS OF THE DRIFT TUBE FOR DRIVING THE ELECTRON STREAM INTO A HELICAL PATH, A SOURCE OF DIRECT CURRENT POWER CONNECTED BETWEEN THE ANODE AND AN ELECTRODE AT THE OTHER END OF THE DRIFT TUBE FOR PROVIDING AN ELECTRIC FIELD THEREBETWEEN, AND CIRCUIT MEANS FOR APPLYING THE CURRENT RECEIVED FROM SAID ANODE AND FROM SAID HIGH FREQUENCY GENERATING MEANS TO A UTILIZATION CIRCUIT.
