Millimetre wavelength performance of the new 16.7 m surface of the Parkes radio telescope.

A semi-automatic survey instrument was installed in the 16.7 m center of the 64 m Parkes radio telescope to obtain observations at millimeter wavelengths. Performance at 7 mm (exceeding 40% efficiency) is contrasted with performance at 3.3 mm (with an approximate efficiency of 16%). Attention is given to telescope gain as a function of wavelength, both for the Parkes telescope and for other radio telescopes operating in the millimeter range.
