Description

The TOFtracker concept, the simultaneous measurement of accurate time and bi-dimensional space coordinates in a single gaseous detector, has been previously demonstrated [1]. The small detector yielded a time accuracy of 77 ps along with a bi-dimensional position accuracy of 38 um over a full active area of 60 x 60 mm2. Recently, a large area, 1550x1250 mm2, detector has been constructed for the same purpose. The detector is composed by a multigap RPC with four gas gaps of 0.3 mm delimited by 2 mm soda-lime glass plates. The High Voltage (HV) is applied to the outer glasses through a resistive layer applied on the glass surface by airbrush techniques. The stack is enclosed in a plastic gas tight box equipped with gas and HV feed-throughs. Signals are induced in 2.54 mm pitch metallic strips located in each side of the plastic box and coupled to both charge-sensitive and timing circuits. In this work, the performance of this device with cosmic ray muons is reported. [1] A. Blanco, P. Fonte, L. Lopes, P. Martins, J. Michel, M. Palka, M. Kajetanowicz, G. Korcyl, M. Traxler and R.
