Electron Loss Cross Sections for a Heavy Ion Beam Probe
Electron loss cross sections of Au and Au2+ by electron and proton impact are calculated by using respectively the Lotz formula and the LOSS and CAPTURE computer codes. The corresponding rate coefficients have also been calculated. Using this information, the signal levels of heavy ion beam probe in the Large Helical Device are estimated. The calculated beam currents at the detector position ar...
متن کاملHeavy ion beam probe advances from the first installation of the diagnostic on an RFP (invited).
Heavy ion beam probes have been installed on a variety of toroidal devices, but the first and only application on a reversed field pinch is the diagnostic on the Madison Symmetric Torus. Simultaneous measurements of spatially localized equilibrium potential and fluctuations of density and potential, previously inaccessible in the core of the reversed field pinch (RFP), are now attainable. These...
متن کاملSweep System Design for a Heavy Ion Beam Probe on MST
The sweep system for the HIBP (Heavy Ion Beam Probe) on the Madison Symmetric Torus is described. The two components of the system are the primary sweep optics and secondary collimation plates. Key issues in the sweep system design are the small entrance and exit ports available on MST, the signi cant toroidal beam motion induced by the strong poloidal magnetic eld and the excessive current loa...

متن کاملThe Vector Probe in Heavy-Ion Reactions
We review essential elements in using the J = 1− channel as a probe for hot and dense matter as produced in (ultra-) relativistic collisions of heavy nuclei. The uniqueness of the vector channel resides in the fact that it directly couples to photons, both real and virtual (dileptons), enabling the study of thermal radiation and in-medium effects on both light (ρ, ω, φ) and heavy (Ψ,Υ) vector m...
