Wave breaking and particle jets in intense inhomogeneous charged beams

Non-perturbative measurement of low-intensity charged particle beams

Non-perturbative measurements of low-intensity charged particle beams are particularly challenging to beam diagnostics due to the low amplitude of the induced electromagnetic fields. In the low-energy antiproton decelerator (AD) and the future extra low energy antiproton rings at CERN, an absolute measurement of the beam intensity is essential to monitor the operation efficiency. Superconductin...

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...

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 ...
