Low Threshold Cherenkov Counter

The Low Threshold Cherenkov Counter (LTCC) has 6 sectors consisting of lightweight mirrors, light connecting cones, PMTs, magnetic fields. It includes both hyperbolic and elliptical mirrors.

The LTCC features superior excellency over CLAS12's forward angular acceptance.

The sectors of the LTCC are filled with perflourobutane (C4F10) gas.
