Yuri | Accelerator | Spectrum | We accept larger m/q values than we like to.
m/q(low) cut ~ 2.08. Decrease ESR energy
from 369.2 -> 368.4 MeV/u

Helmut, Wolfram, Yuri | Accelerator | changed to 70Se | 18:45 changed SIS, ESR setting for 70Se without
predrilling blind change.
E-SIS = 446.55 MeV/u, is centerd as before |

Helmut, Wolfram, Yuri | Accelerator | target TE3UF shift | We see a very strong line at the left end
of spectrum, stronger than all other lines.
When we shift the target TE3UF_H from -35mm |

Helmut, Wolfram, Yuri | Accelerator | change to 72Ge | we change back to 72Ge
just change SIS-energy E = 441.0 MeV/u
beamline energy after target E = 392.9 MeV/u

Helmut, Wolfram, Yuri | Accelerator | scraper optmisation for 72Ge | We tried the scrapers a bit, because right
of peak some background appeared.

Helmut Weick | Accelerator | LISE files for 72Ge, 70Se, 52Mn settings | This is just a Brho selection by the ESR based
on SIS-energy used,
energy-loss in target with calibrated thickness |

Sergey, Helmut | Accelerator | cooler curves for tuning of isochronicity | Variation of quadrupole E01QS03D to change
gamma_t in isoc. mode

Helmut, Sergey, Yuri | Accelerator | change to predrilling an 72Ge | After optimisation of sextupoles we found
a scraper position which makes a narrow peak
and keeps 20% of the injected beam.

Yury, Helmut | Accelerator | added high Brho scrapers | So far only scrapers for low Brho were used:
GE01DS_HI = -58mm (arc from inside) and
GEEXDS2HA = -11.2 (straight from outside)

inside scrapers to narrow and cut the 70Se
line.
