Beam halo collimation in heavy ion synchrotrons

Summary of Session on Beam Losses, Halo Generation and Collimation

The session on beam losses, halo generation and collimation is the first of two sessions of the BEAM07 Workshop, which were devoted to specific CERN-GSI subjects and were meant to be the follow up of last year’s CERNGSI Bilateral Meeting on Collective Effects, which took place on March 30-31, 2006 at the GSI-Darmstadt.

Beam Dynamics in Heavy Ion Fusion

for current multiplication, and it is there that the main challenges of beam dynamics are found. It is being studied in Europe, Russia, and Japan, and is discussed in ref. [1]. A standard design for heavy ion fusion drivers under study in the US. is an induction linac with electrostatic focusing at low energy and magnetic focusing at higher energy. The need to focus the intense beam to a fewmil...

Beam-beam observations in the Relativistic Heavy Ion Collider

Heavy ion beam model for radiobiology.

An ad hoc model of energetic heavy ion beams, including secondary and tertiary particles, has been constructed for predicting radiobiological experiments. While the beam model is relatively primitive, it yields depth-dose and depth-radiobiological calculations in good agreement with experiment upstream of the Bragg peak. Beyond the peak, the model is somewhat coarse grained and seems to underes...

Heavy ion guide: beam transport and diagnostics

Our present plans for a heavy-ion guide system are based on developments at Argonne National Laboratory (ANL) [1]. For the heavy-ion guide, preselection of ions will be done using a superconducting solenoid similar to that being used now in the BigSol spectrometer. Earlier tests with a 1 m long gas cell at low input intensities (below 10 ion/sec) have been carried out at ANL with beams up to 4 ...
