Performance of a High-Precision Drift Chamber During a High-Intensity Test Run

Part of the Ettore Majorana International Science Series book series (EMISS, volume 14)


The high-precision mini-drift-chamber, described earlier2, is envisioned to be used, together with the NAH spectrometer3, at the CERN SPS, to distinguish charm-decay vertices from the primary production point in π̄ p collisions. Such an experiment requires the use of high incident beam fluxes.
