The Cherenkov detector for proton Flux Measurements (CpFM) developed in the frame of the UA9 collaboration is presented. The UA9 experiment at CERN-SPS is investigating the feasibility of crystal-assisted collimation for hadronic beams. The CpFM detector has been conceived to count the protons deflected by the crystal with a precision of 5% per 100 incoming particles. It is a radiation resistant in-vacuum detector consisting of a fused silica radiator bar coupled to a bundle of quartz fibers guiding the light to a photomultiplier (PMT). The readout of the PMT is realized by an ultra-fast (3.2 GHz) analog memory, the WaveCatcher. Another CpFM with a different acquisition chain is now under development to characterize the harmonic content of an extracted beam.
