Compton Camera and Prompt Gamma Ray Timing: Two Methods for In Vivo Range Assessment in Proton Therapy

Proton beams are promising means for treating tumors. Such charged particles stop at a defined depth, where the ionization density is maximum. As the dose deposit beyond this distal edge is very low, proton therapy minimizes the damage to normal tissue compared to photon therapy. Nevertheless, inherent range uncertainties cast doubts on the irradiation of tumors close to organs at risk and lead...

Compton scattering sequence reconstruction algorithm for the liquid xenon gamma - ray imaging telescope ( LXeGRIT )

The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is a balloon born experiment sensitive to γ–rays in the energy band of 0.2–20 MeV. The main detector is a time projection chamber filled with high purity liquid xenon (LXeTPC), in which the three–dimensional location and energy deposit of individual γ–ray interactions are accurately measured in one homogeneous volume. To determine the γ–ray...

Prompt GeV emission in the synchrotron self-Compton model for Gamma-Ray Bursts

The detection in 10 bursts of an optical counterpart emission (i.e. during the prompt GRB phase) that is 10−104 brighter than the extrapolation of the burst spectrum to optical frequencies suggests a synchrotron self-Compton origin for the GRB emission, synchrotron producing the optical counterpart emission. In this model, the second upscattering of the burst photons yields a prompt GeV–TeV emi...

Compton Imaging of MeV Gamma-Rays with the Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT)

The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual γ-ray scattering points, the location of the source in the sky is inferred with Compton kinematics reconstruction. The angular resolution...
