Yuri, Shahab | Runs | FRS valves | We saw reduction in ESR beam life. It turned
out that FRS has opened valves and venting
caused us reduction of the quality of vacuum |

Ragan | General | Stochastic cooling | 1) From SIS, 206Pb67+ @401.17 MeV/u goes to
FRS where only SEETRAM is placed in the target
area to strip off 206Pb67+ to get 206Pb81+.
