A Frictional Cooling Demonstration Experiment with Protons

The Performance of Cosy

At the cooler synchrotron COSY the stochastic cooling system for both transverse and longitudinal cooling came into operation and was successfully applied to an internal target experiment. Further developments to accelerate polarized protons to the maximum momentum 3.3 GeV/c of COSY were carried out. Stacking with the electron cooler was applied to increase the injected proton intensity. In the...

Status Report of a High Luminosity Muon Collider and Future Research and Development Plans

Muon Colliders have unique technical and physics advantages and disadvantages when compared with both hadron and electron machines. They should thus be regarded as complementary. Parameters are given of 4 TeV and 0.5 TeV (c-of-m) high luminosity μμ colliders, and of a 0.5 TeV lower luminosity demonstration machine. We discuss the various systems in such muon colliders, starting from the proton ...

A Muon Collider Scheme Based on Frictional Cooling

Muon Colliders would usher in a new era of scientific investigation in the field of high energy particle physics. The cooling of muon beams is proving to be the greatest obstacle in the realization of a Muon Collider. Monte Carlo simulations of a muon cooling scheme based on Frictional Cooling were performed. Critical issues, which require further study, relating to the technical feasibility of...

Development of an Experiment for Trapping, Cooling, and Spectroscopy of Molecular Hydrogen Ions

Frictional Heating and Neutron Star Thermal Evolution

Differential rotation between the neutron star crust and a more rapidly rotating interior superfluid leads to frictional heating that affects the star’s long-term thermal evolution and resulting surface emission. The frictional heating rate is determined by the mobility of the vortex lines that thread the rotating superfluid and pin to the inner crust lattice. If vortex pinning is relatively st...
