Also have a look at current mm/submm interferometers, and watch out for calls for proposals:

• the Plateau de Bure interferometer (PdBI) www.iram.fr
• the SubMillimeter Array (SMA) www.cfa.harvard.edu/sma/
• the Combined Array for Reserch in Millimeter-wave Astronomy (CARMA) www.mmarray.org
• the Australia Telescope Compact Array (ATCA) www.narrabri.atnf.csiro.au
