  3. Status at the Glasgow-Meeting:

  4. The next months (Sept): • Final setup and technical commissioning of the 4.90 GHz linac, rf-systems, • magnets and beam diagnostics devices of the linac axis. • first injection test

  5. Vacuum tubes and steering magnets 193 tubes („harp“), 384 steering magnets

  6. 90° bending dipoles vacuum chambers All 4 dipole vacuum chambers were fully manufactured at KPH (welding of Al bars and plates) and are installed. 7m first vacuum chamber manufactured in the Institute free aperture in x: ± 8mm and y: ± 7mm

  7. Next steps: (2006) • first tests in diagnostic pulse mode (very low beam power) • up to max. energy of 1.5 GeV • guiding beam in the beam transfer tunnel • tests in cw-operation and high current (100mA) • tests of all beam transfer systems (A1, A2, A4) • first tests for experiments (only 1.5 GeV) • From 2007 on: • beam for experiments (1500 MeV, tests, data taking) • optimal orientation of polarization in all halls and for all energies • possible by use of Wien-filter • variable beam extraction (in steps of ~15 MeV between 872 MeV • and 1320 MeV, and 1500 MeV)

  8. Beam Extraction: correction magnets correction magnets

  9. fixed extraction magnet (1.5GeV) turn 43 turn 30 turn 1 movable extraction magnet (0.87GeV – 1.32GeV) Extraction System of the HDSM Extraction beam paths
