description The LHC col­li­ma­tion sys­tem is cru­cial for safe and re­li­able op­er­a­tion of pro­ton beams with 350 MJ stored en­er­gy. Cur­rent­ly the col­li­ma­tor set-up is per­formed by ob­serv­ing beam loss­es when ap­proach­ing the colli­ma­tor jaws to the beam. For all 100 LHC mov­able col­li­ma­tors the pro­ce­dure may take sev­er­al hours and since it has to be re­peat­ed whenev­er the beam con­fig­u­ra­tion changes sig­nif­i­cant­ly, the col­li­ma­tor setup has an im­por­tant im­pact on the over­all ma­chine op­er­a­tion efficien­cy. To re­duce the col­li­ma­tor setup time by two or­ders of magni­tude the next gen­er­a­tion of the LHC col­li­ma­tors will be equipped with but­ton beam po­si­tion mon­i­tors (BPMs) em­bed­ded into the collimator jaws. This paper de­scribes the BPM de­sign and pre­sents proto­type re­sults ob­tained with beam in the CERN-SPS.
