The VLTI PRIMA Facility
The Phase Referenced Imaging and Microarcsecond Astrometry (PRIMA)instrument was recently delivered to the summit of Cerro Paranal andinstalled as part of the Very Large Telescope Interferometer (VLTI)infrastructure. PRIMA is designed to (i) provide phase-referencedinterferometric imaging at milliarcsecond scales, (ii) enable faint starscience several magnitudes fainter than the current atmospheric limitsof the VLTI, and (iii) provide astrometric measurements at the tens ofmicro-arcsecond level. PRIMA has successfully seen first fringes and iscurrently (as of late 2008) undergoing initial commissioning tests.
