Water Vapor Radiometer for ALMA
Paper in proceeding, 2009

Radiometer for the ALMA project from scratch in 18 months and will deliver 50 units within the next 18 months. The radiometer includes an Optical Relay, Mounting Frame as well as the Radiometer core module. The radiometer core include optics and calibration system as well as a schottky mixer based frontend and a filterbank back-end. These subsystems are supported by a thermal management subsystem, control and communication subsystem as well as a power subsystem. The system and subsystems will be described in the paper.
