Precise Pulse Delivery Control Using Monitor Units in Electron FLASH-RT

In electron FLASH-RT, precise delivery of the correct number of pulses is critical to accurate dose administration in preclinical radiobiological studies. This work investigates the use of LINAC monitor ion chambers to most precisely control FLASH pulse delivery.

Novel Plastic Scintillator for Online Dosimetry in Electron FLASH-RT

The accurate delivery of electrons at FLASH-RT dose rates in radiobiological experiments require new dosimeters that are capable of accurately measuring the radiation dose delivered at >0.55 Gy per pulse (>100 Gy/s) in real-time.

EFLASH Dosimetry On a Conventional Linac Using Pulse-Gated Delivery

To build on previous experiments and improve reproducibility of electron FLASH delivery on a conventional linear accelerator, a pulse-gating circuit was constructed and tested with several dosimeters.
