摘要：The upgraded MERLIN array of telescopes (e-MERLIN), is nearing completion with operations expected in early 2010. The correlator, being built by the Dominion Radio Astronomy Observatory of the Canadian NRC-CNRC is crucial to the performance of the instrument. Station boards and baseline (correlator) boards have been delivered. Signal paths have been tested - with an autocorrelation spectrum being obtained in April, and fringes shortly after. I will discuss some of the design features, in particular the data links, the phase cohering system and the interface to VLBI. The results of a successful call for Legacy observing proposals will be summarised, and finallly a report on the current progress and future plans will be given. e-MERLIN will have a major impact in high resolution radioastronomy, in fields from star formation and through all stages of stellar evolution, to the formation of galaxies at high redshift. This paper is presented on behalf of the e-MERLIN team at Jodrell Bank Observatory.
