The new coordinate-tracking detector ProtoTREK was developed in the Experimental complex NEVOD, MEPhI for the study of near-vertical extensive air showers. The installation consists of two planes of drift chambers, seven in each, and has an effective area of 13 m 2 . The registration system of the new detector gets trigger from scintillator counters and uses the TDC that has been specially designed for this detector. It is based on FPGA Altera Cyclone V and has GPS synchronization with the joint triggering system of the experimental complex NEVOD. A deep learning approach is used to reconstruct multi-muon events registered by ProtoTREK. The paper presents the design of the detector and the first experimental results.
