Track correlator as a fast trigger in the detection of π-μ coulomb bound states

The circuit generates a fast (≈200 ns) trigger in response to two particles (one π and one μ) passing through two scintillation hodoscopes and satisfying criteria of direction and spatial separation. The selection of 4-fold coincidences identifying the relevant tracks is effected by simultaneous RAMs 1 in coincidence with SSI logic.
