Alibava System Classic used for microdosimetry in protontherapy

Researchers from the Department of Radiation Oncology, University of Pennsylvania, Philadelphia, (PA, USA) have used for the first time an Alibava System Classic to perform microdosimetry measurements in a Protontherapy machine.

The microdosimeter consists of an array of micro-sensors that have 3D cylindrical electrodes of 15 µm diameter and a depth of 5 µm within a silicon membrane, resulting in a well-defined micrometric radiation sensitive volume. The first measurements have been taken with a 241Am source and the results have been published in Applied Physics Letters [1].

Measurements using real proton beams, as shown in the picture, have also been taken and will be published soon.
