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

چکیده
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 initial direction (Compton imaging), as well as to reject background, the correct sequence of interactions has to be determined. Here we report the development and optimization of an algorithm to reconstruct the Compton scattering sequence and show its performance on Monte Carlo events and LXeGRIT data.

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...

LXeGRIT – Liquid Xenon Gamma-Ray Imaging Telescope – is the first prototype of a Compton telescope for MeV γ-ray astrophysics based on a LXe time projection chamber. One of the most relevant figures of merit for a Compton telescope is the detection efficiency for γ-rays, which depends on diverse contributions such as detector geometry and passive materials, trigger efficiency, dead time, etc. A...
