Abstract
An ionization chamber with spatial distribution electrode for monitor hadron beam currents used for therapeutic treatment. Ionization chamber comprises humidity control, environmental sensing and real-time correction thereof. A flexible hermetic seal provide for ambient pressure equalization. X-Y electrode planes measure Gaussian distribution of incident particle beam. Methods described herein are suitable to fabricate highly accurate, low scattering electrodes with high spatial resolutions.
