Abstract
The ALMA Photonic LO system consists of a unique combination of a widely tunable and low-phase-noise millimeter-wave LO reference transmission, combined with a precise round-trip phase correction system based on an optical interferometer. The first installation of the system is now in place and supporting the initial phase of scientific commissioning of the telescope.
