Generating high dose rates using laser-based sources
In collaboration with INRS – Varennes, we’re investigating the use of a high powered laser source for the creation of an electron source in air. Ultra-short pulses in the femtosecond range are tightly focused using a high numerical aperture lens to create an electron source in the MeV range. Our current focus is to optimize the source to produce dose rates in the >40 Gy per second range to be used as a tool to investigate the biological FLASH effect (decreased normal tissue effects for the same tumor effect) observed in radiotherapy at these high dose rates. This work involves aspects of dosimetry of high dose rate beams and radio-protection.
