Dr. Brent Carlson, of the National Research Council Canada, will present the NRAO-Socorro colloquium. His talk is "Incoherent Clocking." Radio interferometers require synchronization of all signal processing to a coherent timing reference prior to correlation and (optionally) tied-array beamforming. Ideally, digitization occurs as close to the feed as possible for maximum stability and signal fidelity. In this talk, Carlson will describe a method of "incoherent clocking" whereby a) each receiver operates using its own free-running clock, b) the phase and frequency of each antenna clock is measured at the central site, and c) the digitized science data is digitally-corrected at the central site. 11 a.m. in the auditorium of the Domenici Science Operations Center (NRAO).
