  4. Beam position monitor challenges • Wide range of currents • Tight requirements for position accuracy for intense beams – Δx < 0.1mm, x = ±100mm Beam position monitor features • A special attention to pick-up construction • Careful design of front-end electronics FAIR meeting on 19 March 2009 (Protvino)

  5. BPM Applications Bunch-by-bunch operation to get a distinguish between bunches Closed orbit feedback Turn-by-turn variation of any bunch in the train SIS100/300 Lattice function reaction distortion FAIR meeting on 19 March 2009 (Protvino)

  6. Example of a electrode arrangement for a linear-cut BPM and the scheme of the position determination. FAIR meeting on 19 March 2009 (Protvino)

  7. BPM electronics FAIR meeting on 19 March 2009 (Protvino)

  8. BPM basestation with analog front-end FAIR meeting on 19 March 2009 (Protvino)

  10. Ionization profile monitor • Advanced concept with high resolution and fast profile measurements • IPM is a subject of GSI-ITEP collaboration FAIR meeting on 19 March 2009 (Protvino)

  11. Ionization profile monitor. Fast profile readout. FAIR meeting on 19 March 2009 (Protvino)

  12. Permanent magnet quadrupole at one of the ITEP synchrotron output channel Examples of ion beam optic elements constructed in ITEP on the base of permanent magnets PM Lens design and rods magnetization scheme for 352 MHz Prototype Alvarez DTL Tank for the CERN SPL FAIR meeting on 19 March 2009 (Protvino)

  13. Construction drawing (overview from the front side) of a typical profile grid. To reduce the number of required signal processing channels, a larger spacing outside the center has been chosen. Roughly estimated number of secondary electrons per incident ion with the energy of incident ion as a parameter. The data have been scaled ~z1.5 from various data found in the literature Secondary emission monitor FAIR meeting on 19 March 2009 (Protvino)
