Dosimetric Characteristics of 6 MV X-bandLINAC Cavity

An X-band linear accelerator (LINAC) system for radiation therapy has beendeveloped. This system is designed to utilize a dual-head gantry radiotherapysystem by Sungkyunkwan university. The electron acceleration cavity is plannedto generate 6 MV photon beam with 70 mA peak current using peak power of1.7 MW RF power. Our study details the development and dosimetric evaluationof an X-band linear accelerator for radiation therapy, equipped with a dualheadgantry for improved treatment precision. Dosimetric analysis was performedusing a solid water phantom and an ionization chamber to measure the PercentageDepth Dose (PDD), with the results affirming the simulation data from theEGSnrc Monte Carlo code. Adjustments were proposed to address beam spotbias caused by the ion pump’s placement. The experimental outcomes demonstratedthe system’s potential for precise cancer treatment, corroborating theeffectiveness of the X-band LINAC technology.
