  • Research on this contract can be divided into two general topics: (1) H/sup -/ formation collision processes, and (2) the determination of scattering cross sections used to diagnose plasma properties. Research progress during the last two months is presented.

  • Research on this contract over the past five years can be divided into several general topics: (1) D/sup -/ formation processes for ion source related work, (2) collisions between atomic H or D and multiply-charged impurity ions for the diagnosis of plasma properties, and (3) the study of alpha particle collisions to determine confinement times. For topic (1), we completed theoretical calculations on the differential (angular) scattering of H/sup 0/ and D/sup 0/ on Cs, and detemined the mechanisms and trends in the electron detachment cross sections for collisions of H/sup -/ and D/sup -/ with alkali and heavy alkalinemore » earth atom systems. For topic (2), a cross section scaling rule was determined for electron removal from atomic hydrogen by multiply charged ion collisions for charge states q = 1 to 50 and for collision energies from 50 to 5000 keV/amu. On topic (3), we completed He/sup + +/ + Li double electron capture and single ionization cross section calculations from 50 to 400 keV/amu for use in studies on alpha distributions in magnetically confined plasmas. The cross section values are such that this diagnostic procedure appears tractable.« less

  • Research on this grant is devoted to the calculation of heavy particle collision cross sections needed for diagnostic studies of magnetic fusion plasmas. This work requires the development and testing of new theoretical techniques, and the implementation of benchmarked methods to collisions pertinent to fusion reactors. In the last context, we have provided the cross sections needed for modelling of charge exchange recombination on ASDEC, Rutherford scattering experiments on JT-60, carbon pellet based alpha particle diagnostics for CIT, and a proposed current drive application for ITER. Further, a large compilation of n/ell/ charge exchange cross sections for C/sup 6 +/more » and O/sup 8 +/ collisions has been made for the inclusion in major IAEA report on this subject.« less
