Cuprate superconductors including Bi2Sr2CaCu2O8+δ (Bi2212) have been researched to elucidate the mechanism of high-Tc superconductivity for a long time. We have developed a low-temperature coolable G-HAUP and evaluated the time-reversal symmetry of Bi2212 by measuring the reciprocal and non-reciprocal circular birefringence and circular dichroism in the pseudogap.
