We have demonstrated that GaN Schottky diodes can be used for high energy (64.8 MeV) proton detection. Such proton beams are used for tumor treatment, for which accurate and radiation resistant detectors are needed. Schottky diodes have…
The major advantage of proton therapy over conventional radiotherapy is the dose deposition pattern, enabling precise coverage of the tumour volume while sparing nearby healthy tissues. However, accurate control of the proton beam range…
In the last decade, several new imaging gaseous detectors, called micro-pattern gaseous detectors, have been conceived and rapidly developed. In this paper, the most popular designs of these detectors and their applications to high energy…
The proton radiography diagnostic is widely used in laser-plasma experiments to make magnetic field measurements. Recent developments in analysis have enabled quantitative reconstruction of path-integrated magnetic field values, but making…
Charged Particle Therapy is a technique for cancer treatment that exploits hadron beams, mostly protons and carbons. A critical issue is the monitoring of the dose released by the beam to the tumor and to the surrounding tissues. We present…
Low Gain Avalanche Detectors (LGADs) are fast silicon sensors with potential for high-resolution proton beam monitoring. In this work, we investigated their response in a 60 MeV proton beam from an AIC-144 cyclotron. Several features of the…
Imaging biological molecules in the gas-phase requires novel sample delivery methods, which generally have to be characterized and optimized to produce high-density particle beams. A non-destructive characterization method of the transverse…
