We present the results of a series of experimental tests demonstrating that bent crystals may act efficiently as primary collimator in a hadron collider. The deflected protons are easily collected in a bulk secondary absorber. Such a system is well suited to clear the halo surrounding the circulating beam. The experiments, performed in the SPS at 120 GeV/c. also give a clear indication that a similar technique can be extended to the LHC.
