DEBRIS (Disk Emission via a Bias-free Reconnaissance in the Infrared/submillimetre) is an open time project on Herschel which will do an unbiased statistical survey for debris disks around the nearest stars. A total of 446 primary stars, ranging in spectral types A0 through M7 will be examined at 100 microns to a level that will permit detection of masses comparable to our own Kuiper belt. One complication is the possibility that some of the systems have previously undetected low mass companions. Such a companion would lead to uncertainties in the basic disk properties derived for any disks detected by DEBRIS. Therefore, we have undertaken a program to use the Lick Shane 3-m telescope and its adaptive NIR optics system at J, H, and K to look for previously unknown companions. In June 2009, we obtained the first data for the program and identified several binary stars and one triple system. We report on the first observational results from data taken both in June and in a October 2009 run.
