DESCRIPTION
Neutron-rich isotope production in 238U+Be collisions
The aim of this experiment is to explore the production of neutron-rich isotopes in cold-fragmentation reactions induced by a 238U beam at 1 A GeV on a Be target.
TECHNICAL INFO
Technical information
5. Data acquisition
- MBS
- DAQ handling
- Online analysis (PAW, SATAN )
- Parameter list
6. FRS handling
- Before starting (loading ion-optical files, starting different programs ??)
- Setting the FRS (loading a reference setting and scaling)
- Saving a setting
- different programs SD, DI, setting current grids, change the seetram sensitivity...etc...??)
How to get the status of all devices in the beam line
7. SEETRAM calibration
FRS calibration
1. Reference setting RUN94_E: beam centered from SIS to S4 with the 60 mg/cm2 Nb foil
- Check that the beam is centered at the target with the current grids
- Check that the beam is centered at S1, S2, S3 and S4
2. Center at S2 with the 1023 mg/cm2 Be target and at S4 with the Sc2
4. Set electronics
5. Dispersion calibration: scale the setting by 0.5% and 1%
6. Targets and degraders calibration: ToF calibration
- 2615 mg/cm2 Be, Sc2, 4.3 g/cm2 degrader and 108 mg/cm2 Nb
- 2615 mg/cm2 Be, Sc2, 4.55 g/cm2 degrader and 108 mg/cm2 Nb
- 2615 mg/cm2 Be, Sc2, 4.92 g/cm2 degrader and 108 mg/cm2 Nb

7. Primary beam defocused to calibrate the position dependence of the MUSIC energy loss
8. SEETRAM calibration
9. First setting with fragments: S2 and S4 position calibration (MW in)
