Resistive Plate Chambers for brain PET imaging and particle tracking and timing (TOF-tracker)

Abstract

In this work we explore readout architectures for the simultaneous high-resolution timing and bidimensional tracking of charged particles with Resistive Plate Chambers (TOF-tracker) and for the accurate detection of gamma rays for PET imaging. On 625 $c{m}^2$ of active area we obtained a time resolution of 61 ps $\ddot{I}ƒ$ and bidimensional position resolution below 150 $\hat{I}¼$m $\ddot{I}ƒ$ for the tracking and timing of charged particles from cosmic rays. An intrinsic precision of 0.49 mm FWHM was determined for the localization of a small $β^+$ source via the detection of its annihilation radiation.
