Description
FLASH Radiotherapy is an emerging novel type of radiotherapy where dose rates of higher than 40Gy/s are used compared to conventional radiotherapy where less than 1Gy/s are used. This study will consider the usage of Photons to achieve the FLASH effect. Whilst not understood, dose rates of this magnitude harm healthy tissues less than that of tumours. There is currently a lack of research into FLASH radiotherapy using Photons, especially on RF Linacs at a clinical scale. The study covers the research and evaluation of a preliminary design for a 6 MeV L-Band, 10 cell RF Linac and a corresponding X-Ray target, with paths of optimisation identified, to deliver 40Gy/s within a clinical scale. The main barrier to achieving this is the high temperatures due to heating in the X-Ray target, reaching a peak temperature of 2909◦C in tungsten at a SSD of 0.3m and 881 ◦C in copper, with an average temperature of 246.7 ◦C.
