Simulations of ionisation triggering

We review recent pilot simulations that incorporate feedback from ionising radiation in SPH calculations of star forming clouds. In the case that the ionising radiation source is located within the star forming cloud, the inhomogeneity of the cloud significantly modifies the way that feedback operates compared with spherically symmetric cloud models. Inflow/outflow behaviour develops, combining...

Beam Cooling with ionisation losses

This novel type of particle “cooling”, called Ionization Cooling, is applicable to slow ( ) ions stored in a small ring. The many traversals through a thin foil enhance the nuclear reaction probability, in a steady configuration in which ionisation losses are recovered at each turn by a RF-cavity. For a uniform target “foil”, typically few hundred v ≈ 0.1c μg cm thick, transverse betatron oscil...

Muon Ionisation Cooling Experiment MICE

The Muon Ionisation Cooling Experiment (MICE) is currently under construction at the Rutherford Appleton Laboratory. MICE will prove the technology necessary for muon ionisation cooling. In ionisation cooling, particle beam emittance is reduced by passage through an energy absorbing medium and RF cavities. In its final configuration, MICE will consist of a 5.5 metre cell of an ionisation coolin...

Radiative effects of tropospheric ionisation

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Despite the increasing evidence that cosmic ray variations may influence clouds and climate, there has been little discussion of the direct radiative effects of atmospheric ionisation. Laboratory experiments show that hydrated molecular cluster-ions, form...
