TRANSVERSE-FIELD ACCELERATOR USING A DIELECTRIC MEDIUM

A GAS-LOADED WIGGLER IS PROPOSED AS A METHOD FOR THE COUPLING OF INTENSE OPTICAL RADIATION AND CHARGED PARTICLES TO ACHIEVE HIGH-GRADIENT ACCELERATION OF 100 MEV/M OR MORE. THE METHOD MINIMIZES THE LOSS OF ENERGY DUE TO SYNCHROTRON RADIATION AT HIGH PARTICLE ENERGIES WHILE STILL ACHIEVING HIGH GRADIENT FIELDS. THE THEORY OF THE GAS-LOADED INVERSE FREE ELECTRON LASER (IFEL) IS THE SAME AS THE VACUUM IFEL WITH THE EXCEPTION THAT THE PHASE-MATCHING CONDITION BETWEEN THE OPTICAL FIELD AND THE CHARGED PARTICLE IS CHANGED AND THAT MULTIPLE SCATTERING HAS BEEN INTRODUCED. THE LATTER EFFECT IS TO BE ANALYZED IN THIS PROGRAM USING A MONTE-CARLO SIMULATION. AN EXPERIMENT IS TO BE DESIGNED USING THE PARAMETERS FOUND FROM THE PROGRAM AND REALISTIC PARAMETERS FROM CONVENTIONAL ACCELERATORS THAT CAN BE USE TO INJECT HIGH ENERGY BEAM INTO THE PROPOSED DEVICE.
