Yuri and Helmut have been extensively involved in tuning and optimizing of the FRS.

26th March, 2020 (Evening setting):
1) 206Pb67+ beam from SIS @401.17 MeV/u.
2) SEETRAM in target area of FRS is used for stripping the beam from SIS to get 206Pb81+ and is then transported to ESR @400 MeV/u. (SEETRAM consists of three Ti foils of ~10 um thickness which are used for stripping purpose (more info: https://www-win.gsi.de/frs-setup/ ))
3) SL1 slits are opened +-10 mm to get rid of other charge states of 206Pb and only transport 206Pb81+ through FRS.

27th March, 2020 (Evening setting):
1) Different target (Be 1-6 g/cm2 with Nb backing) and degrader (Al)thicknesses are used for the optimization of 206Pb81+ with matter in FRS to get the beam with @400 MeV/u in ESR.
2) 206Pb67+ beam from SIS @540-560 MeV/u.
