SO… SORRY FOR POSSIBLE INACCURATE EXPLANATIONS OF THE EXPERIMENTAL FACILITIES!!!
2. The Experiment:
2. The Experiment:
Production:
Sm-152 pulses of ~ 1µs duration hit a Be-target and pro-duce the ions → well-defined pro-duction time

2. The Experiment:
2. The Experiment:
Cooling (first 6-10 seconds):
2. The Experiment:
Cooling (first 6-10 seconds):
stochastic cooling: the motion of the particle is sampled with a pick-up and corrected by a kicker → switched off after 5s
2. The Experiment:
Cooling (first 6-10 seconds):
stochastic cooling: the motion of the particle is sampled with a pick-up and corrected by a kicker → switched off after 5s
electron cooling (permanent): ion beam crossed with an elec-tron beam of smaller tempera-ture → ions lose energy by scattering with the electrons
