DESCRIPTION:Today's radial velocity (RV) instruments for planet detection 
 are limited by systematic errors due to their seeing-limited telescope inp
 uts. In the era of adaptive optics at large telescope facilities worldwide
 \, it is now possible to use a diffraction-limited input for an RV spectro
 graph\, reducing their size\, overcoming intrinsic effects and improving t
 heir stability and precision.\n \niLocater\, a new RV spectrograph being d
 eveloped at the University of Notre Dame\, will be installed at the Large 
 Binocular Telescope (LBT)\, AZ\, USA. By using the two 8.4m primary mirror
 s of the telescope\, each with its own independent AO system\, light can b
 e coupled to single-mode optical fibres which feed a temperature-stabilise
 d diffraction-limited spectrograph operating at cryogenic temperatures. Co
 mbined\, mitigates the effects limiting today's leading RV instruments and
  will allow single-measurement precision for RVs below 1m/s for the first 
 time.
