The aim of the measurement is to test the instrument prototype LUPIN around the CNAO accelerator. The interest is to measure in the synchrotron hall, in the treatment rooms, in the mazes and outside the shielding walls. The beam delivery should be pulsed with the possibility to vary the beam intensity and the repetition rate. The results will be compared with passive measurements performed...

A monolithic silicon telescope (MST) consisting of a surface ΔE detector 2 µm in thickness coupled to an E detector about 500 µm in thickness made out of a single silicon wafer was recently proposed for the microdosimetric characterization of hadron beams. The ΔE detector is segmented in a matrix of micrometric cylindrical diodes (about 9 µm in diameter, 2 µm in height).
The silicon...

The aim of the project is to test a GEM detector for beam monitoring in hadrontherapy facilities, namely to control the characteristics of the beam before entering the patient, its fragmentation and to monitor the non-therapeutic dose to the patient. GEM detectors have already been used for beam monitoring at CERN and at the Frascati INFN Laboratory, for flux measurements of neutrons (n_TOF at...

Neutron production at hadrontherapy facilities is a source of non-therapeutic dose to patients. To study this dose it is necessary to measure the neutron fluence and spectra. Our proposal is to couple a GEM detector with several types of neutron converters. Using this device, we can then characterize components of the neutron spectrum and investigate the detectors reliability as a neutron...

Semiconductor pixel detector Timepix can be used to measure the geometrical characteristics of the beam, such as the lateral penumbra, the beam flatness and the beam broadening while passing through different samples.
1. Investigations of Secondary Ion Distributions in Carbon Ion Therapy Using the Timepix Detector
The purpose is to investigate the potential for beam monitoring by detecting...

Centre for Medical Radiation Physics is developing quality assurance (QA) instrumentation for radiation therapy. Two types of experiments are proposed on C-12 and proton therapeutic beams.
1. High Spatial Resolution SOI Microdosimetry on proton and C-12 beams.
Microdosimetry based RBE study on C-12 and proton therapeutic beams along the Bragg Peak (BP) and SOBP (Spread-Out -BP) using SOI...
