Heavy particle linear accelerator with continuous variation of output energy

Claim 1

A LINEAR ION ACCELERATOR, COMPRISING A SUBSTANTIALLY LINEARLY EXTENDING DELAY CIRCUIT, A SOURCE OF IONS PROVIDED WITH MEANS FOR DIRECTING A BEAM OF SAID IONS ALONG THE LINEAR EXTENSION OF SAID DELAY CIRCUIT, MEANS OPERABLE TO EXCITE IN SAID CIRCUIT A TRAVELLING WAVE HAVING AT LEAST ONE SPACE HARMONIC COMPONENT PROPAGATING WITH A PHASE VELOCITY IN THE SAME DIRECTION AS SAID BEAM, AND MEANS FOR ADJUSTING SAID BEAM VELOCITY TO BE SYNCHRONOUS WITH THE PHASE VELOCITY OF A PREDETERMINED DISPERSIVE SPACE HARMONIC, SAID CIRCUIT BEING FORMED OF A CHAIN OF CASCADE COUPLED CELLS, SAID CELLS BEING DIMENSIONED TO ENSURE A SUBSTANTIALLY CONSTANT LENGTH OF THE EFFECTIVE PROPAGATION PATH OF SAID WAVE IN EACH CELL, AND THE SIZE OF SAID CELLS ALONG SAID LINEAR EXTENSION INCREASING SUBSTANTIALLY IN PROPORTION TO THE CUBE ROOT OF THE DISTANCE OF EACH RESPECTIVE CELL ALONG SAID LINEAR EXTENSION TO A PREDETERMINED POINT AHEAD OF SAID CIRCUIT.
