We report on the white dwarf cooling sequence of the old globular cluster NGC6752, which is chemically complex and hosts a blue horizontal branch. This isone of the last globular cluster white dwarf (WD) cooling sequences accessibleto imaging by the Hubble Space Telescope. Our photometry and completeness testsshow that we have reached the peak of the luminosity function of the WD coolingsequence, at a magnitude m_F606W=29.4+/-0.1, which is consistent with a formalage of ~14Gyr. This age is also consistent with the age from fits to themain-sequence turnoff (13-14Gyr), reinforcing our conclusion that we observethe expected accumulation of white dwarfs along the cooling sequence.
