TOFtracker: gaseous detector with bidimensional tracking and time-of-flight capabilities

Particle identification by time-of-flight requires the simultaneous measurement of the passing time and the trajectory of particles. It may be usefull that each tracking station measures both quantities, providing better timing accuracy by redundancy and independence from an external initial time counter. In here we demonstrate a 5-gap timing RPC equipped with patterned electrodes coupled to both charge-sensitive and timing circuits, yielding a time accuracy of 77 ps along with a position accuracy of 38 μm.
