A particle-core model for inhomogeneous and mismatched charged particle beams

Wave breaking and particle jets in intense inhomogeneous charged beams

Charged Particle Therapy with Mini-Segmented Beams

One of the fundamental attributes of proton therapy and carbon ion therapy is the ability of these charged particles to spare tissue distal to the targeted tumor. This significantly reduces normal tissue toxicity and has the potential to translate to a wider therapeutic index. Although, in general, particle therapy also reduces dose to the proximal tissues, particularly in the vicinity of the t...

Direct charged-particle measurements with stable beams

A number of examples for direct measurements in nuclear astrophysics are given in order to address several important issues. First, recent results for the 16O(p,γ)17F reaction are discussed and it is shown how an improvement in reaction rate precision allows for significantly improved astrophysical predictions in connection with massive AGB stars. Second, we discuss improved experimental techni...

Synthetic-diamond detectors for charged-particle beams dosimetry

Hadron cancer-therapy with high-energetic heavy-ions (HI) as available at the SIS facility at GSI Darmstadt [1] as well as the research with beams stopped in biological material as realized at the UNILAC at GSI in general require the precise knowledge of beam conditions and its composition as well as the applied dose within less than 1% in most cases. At these sites beam preparation, its applic...

Chaotic collisionless evolution in galaxies and charged-particle beams.

Both galaxies and charged particle beams can exhibit collisionless evolution on surprisingly short time scales. This can be attributed to the dynamics of chaotic orbits. The chaos is often triggered by resonance caused by time dependence in the bulk potential, which acts almost identically for attractive gravitational forces and repulsive electrostatic forces. The similarity suggests that many ...
