VLA Test/Observation Coordination Meeting B.G. Clark June 17, 2004 1. eVLA Current status: Antenna 13 has yielded fringes at L band as well as X. Fringe rotation is still not working. There is new software for the L302, the module containing the fringe rotator, but it was not quite ready for today. Next week, the antenna will be taken for reworking the fiber, with completion scheduled for July 8. At about that time, we expect additional equipment in the antenna, to be able to switch bands under computer control, and to have additional bands. The antenna will be moved to station W10 about the fifteenth of July, and by then or shortly thereafter, it will have two IFs and four bands. Because of the two IFs and the strong phase response across the bandpass (relative to other VLA antennas), it will be useful for science only for spectral line observations. Antenna 14 is expected to have first fringes (as an EVLA antenna) about September 1. It is planned to speedily equip it with four IFs. About that time also, we should be able to find some manpower to work on the phase response problem, so antenna 14 should be able to do science with the array in mid to late fall.
