  In this paper the growth of a 16mm diameter Ce-doped Tl$_2$NaYCl$_6$ and its
characterization as a gamma-ray detector are reported. With a 16 mm dia. x 8 mm
cylindrical sample, energy resolution of 4.1% (FWHM) at 662 keV and light yield
of 27,800ph/MeV are measured. Decay times of 91 ns (34%), 462 ns (52%), and 2.1
microseconds (15%) are calculated. The x-ray excited emission spectrum exhibits
bands that are similar to other Tl-based elpasolite scintillators like
Tl$_2$NaYCl$_6$:Ce.
