On-line Monitoring of Fluence Distributions and Imaging of Scanning Ion Beams
نویسندگان
چکیده
In this paper we describe the design of an ion beam monitor developed to control irradiations of biological samples with ions at GANIL (Grand Accélérateur National d’Ions Lourds). This device can be used as an on-line monitor to provide transverse fluence distributions for active scanning ion irradiations. It can also be used as an interceptive beam imager to provide beam profiles or fluence depth distributions. A prototype of the monitor has been tested at GANIL with five different ion beams, having intensities from 10 to 10ions per second. Real time transverse fluence distributions have been obtained with a 1mm spatial resolution.

Evaluation of the electron energy fluence and angular distributions from a clinical accelerator. A BEAMnrc Monte Carlo study
Background: Understanding of the incident electron energy and angular distributions from clinical electron accelerators (linacs) is important for dosimetry and treatment planning. The most important goals of this study were to evaluate the energy fluence and angular distributions of electron beams from a Neptun 10PC linac using the Monte Carlo (MC) code. Materials and Methods: The lina...

Introduction: Electronic portal imaging devices (EPIDs) could potentially be useful for intensity-modulated radiation therapy (IMRT) and VMAT QA. The data density, high resolution, large active area, and efficiency of the MV EPID make it an attractive option. However, EPIDs were designed as imaging devices, not dosimeters, and as a result they do not inherently measure dose in ...
متن کاملFluence correction factor for graphite calorimetry in a clinical high-energy carbon-ion beam.
The aim of this work is to develop and adapt a formalism to determine absorbed dose to water from graphite calorimetry measurements in carbon-ion beams. Fluence correction factors, [Formula: see text], needed when using a graphite calorimeter to derive dose to water, were determined in a clinical high-energy carbon-ion beam. Measurements were performed in a 290 MeV/n carbon-ion beam with a fiel...
متن کاملMeasurement of fluence, LET, and dose in a carbon ion spread-out Bragg-peak using fluorescent nuclear track detectors and an automated reader
For the assessment of radiation effects of clinical ion-beams, dosimetry has to be complemented by information on particle-energy distribution or related quantities. Fluorescence nuclear track detectors made from C,Mg-doped alumina single crystals allow for the quantification of ion track density and energy loss on a single-track basis. In this study, their feasibility and accuracy to quantify ...
متن کاملIntegration of scanning probes and ion beams.
We report the integration of a scanning force microscope with ion beams. The scanning probe images surface structures non-invasively and aligns the ion beam to regions of interest. The ion beam is transported through a hole in the scanning probe tip. Piezoresistive force sensors allow placement of micromachined cantilevers close to the ion beam lens. Scanning probe imaging and alignment is demo...
