Fast forward detector for MPD/NICA project: Concept, simulation, and prototyping

Concept of a fast forward detector (FFD) developed as part of Multi-Purpose Detector (MPD) setup for future experiments with beams of nuclear collider NICA is described. The FFD is aimed at triggering nucleus-nucleus collisions at the center of the MPD setup and generating start pulse for TOF detector. Two units of the detector module were designed, produced, and tested with cosmic rays and proton beam. The time resolution obtained in the measurements is ∼30 ps (sigma). Results of simulation, prototype developing and experimental tests are discussed.
