Secondary pion beams at GSI
Description
Protons and 12C ions from the 18 Tm synchrotron have been used to irradiate a production target of beryllium, with the resulting pion beams being transported to the nearest downstream experimental area. The beam line accomodates pion momenta up to 2.8 GeV/c and has a momentum acceptance of 8%. For 12C projectiles with the maximum energy of 2A GeV the negative pion yields reach values of 1 x 107/spill near the peak of the momentum distribution around 1 GeV/c, if extrapolated to the space charge limit of the synchrotron. The corresponding p-induced yields at 3.5 GeV are smaller except for hard pions for which the production exceeds the 12C-induced intensities because of the higher energy per nucleon. (orig.)
