The GATE-RTion/IDEAL Independent Dose Calculation System for Light Ion Beam Therapy

Frontiers in Physics, 2021
Patient specific quality assurance can be improved using an independent dose calculation system. In addition, the implementation of such a system may support light ion beam therapy facilities in reducing the needs for beam time, by substituting some of ...

Numerical and experimental studies of the carbon etching in EUV-induced plasma [PDF]

, 2016
We have used a combination of numerical modeling and experiments to study carbon etching in the presence of a hydrogen plasma. We model the evolution of a low density EUV-induced plasma during and after the EUV pulse to obtain the energy resolved ion ...
