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 Fusion Sources*
In Heavy-Fusion and in other applications, there is a need for high brightness sources with both high current and low emittance. The traditional design with a single monolithic source, while very successful, has significant constraints on it when going to higher currents. With the Child-Langmuir current-density limit, geometric aberration limits, and voltage breakdown limits, the area of the so...
متن کاملHeavy ion beam model for radiobiology.
An ad hoc model of energetic heavy ion beams, including secondary and tertiary particles, has been constructed for predicting radiobiological experiments. While the beam model is relatively primitive, it yields depth-dose and depth-radiobiological calculations in good agreement with experiment upstream of the Bragg peak. Beyond the peak, the model is somewhat coarse grained and seems to underes...
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...
