Helmut Weick | Accelerator | 70Se setting | If gamma_t = 1.3955 Tm stays, we will need
Brho = 6.21902 Tm for 70Se.
The corresponding ESR Brho setting will be |

Akash, Nic, Jelena, Zsolt | Accelerator | No Beam! | 08.43am: Beam stopped. HKR looking into it.
Reason: they mentioned they don't know yet!
