SYSTEMS AND METHODS FOR CARGO SCANNING AND RADIOTHERAPY USING A TRAVELING WAVE LINEAR ACCELERATOR BASED X-RAY SOURCE USING CURRENT TO MODULATE PULSE-TO-PULSE DOSAGE

摘要

Provided herein are systems and methods for operating a traveling wave linear accelerator to generate stable electron beams at two or more different intensities by varying the number of electrons injected into the accelerator structure during each pulse by varying the electron beam current applied to an electron gun. The electron beams may be used to generate x-rays having selected doses and energies, which may be used for cargo scanning or radiotherapy applications.
