A multi-site microdosimeter for clinical beam characterization

Frontiers in Sensors
Different types of radiation cause varying levels of biological damage, even when the physical dose is the same, due to the unique way energy is distributed at the subcellular level.

Electron beam monitoring of a modified conventional medical accelerator with a portable current transformer system traceable to primary electrical standards

Medical Physics, Volume 52, Issue 4, Page 2581-2592, April 2025.
Abstract Background Ultra‐high dose rate radiotherapy (UHDR) delivers therapeutic doses at rates >40 Gy/s in a fraction of a second, aiming to enhance the therapeutic ratio through the FLASH effect. The substantial increase in UHDR beam current poses serious challenges for conventional active dosimeters.

Charged hadron beam therapy : fast computational physics methods [PDF]

, 2011
Charged hadron beams have been investigated for use in radiation therapy of cancer since the 1940’s due to their unique potential to place tightly conformal radiation doses deep inside tissue.

High-gradient low-β accelerating structure using the first negative spatial harmonic of the fundamental mode

Physical Review Accelerators and Beams, 2017
The development of high-gradient accelerating structures for low-β particles is the key for compact hadron linear accelerators. A particular example of such a machine is a hadron therapy linac, which is a promising alternative to cyclic machines ...

Transfer line scattering model of therapeutic hadron beams and applications to nozzle and gantry optimization

Physical Review Special Topics. Accelerators and Beams, 2013
The field of hadron therapy is growing rapidly with several facilities currently being planned, under construction or in commissioning worldwide. In the “active scanning” irradiation technique, the target is irradiated using a narrow pencil beam that is ...

Solution Radioactivated by Hadron Radiation Can Increase Sister Chromatid Exchanges.

PLoS ONE, 2015
When energetic particles irradiate matter, it becomes activated by nuclear reactions. Radioactivation induced cellular effects are not clearly understood, but it could be a part of bystander effects.

Towards Laser Driven Hadron Cancer Radiotherapy: A Review of Progress

Applied Sciences, 2014
It has been known for about sixty years that proton and heavy ion therapy is a very powerful radiation procedure for treating tumors. It has an innate ability to irradiate tumors with greater doses and spatial selectivity compared with electron and ...
