setup and beam for Mu Cap experiment in

setup and beam for Mu. Cap experiment in πE 3 area (contribution by C. Petitjean to Gatchina meeting June 14 -17) beam elements in area for Mu. Cap: separator – kicker - triplet – slit – triplet hidden part of πE 3 beam <- length in area up to focus ~10 m -> + 3 m additional length for apparatus and TPC rollout (setup shown here for ALC μSR experiments)

beamline configuration in area πE 3 for Mu. Cap exp. 2004 the total length Q 9 -exit to center of TPC is 10. 0 meters
