Various geometrical orientations for ion chamber's long axis (central cylinder), magnetic field (arrow), and radiation beam (transparent rectangular prism) as used in Monte Carlo simulation and experimental measurements.
NE2571 relative dose deposited as a function of magnetic field in orientations I–IV as determined in Monte Carlo simulations, and orientations I and II as determined in the measurements previously published by Meijsing et al. (Ref. 10 ). Please note the simulation data points in orientations III and IV nearly lie on top of each other.
PR06C relative dose deposited as a function of magnetic field in orientations I–IV for simulations, and orientations I and II for measurements.
Simulation geometrical setup and PENELOPE simulation parameters for the two chambers.
Chamber kQ values without the magnetic field are compared with the previously published results. Errors quoted are 1 standard deviation.
Ratio of readings with the magnetic field indicated to no magnetic field as a function of field size. All measured values are ±0.0015.
P pol and P ion values as a function of magnetic field. Calculation formalism used as per column reference. All values are ±0.002.
