Nature of problem:
Using analytic fits to the experimental cross sections for coupled H, H2 and H2+ interactions in MFE plasmas, a general purpose multigroup cross section and reaction rate processor is constructed for transport, hydrodynamics and plasma physics applications. Cross sections and rates are folded over user specified plasma temperature and density profiles and Maxwellian backgrounds in nested numerical integration routines. Adaptive quadrature routines are employed in requisite integrations. Output can be coupled directly to a number of production multigroup Sn and Monte Carlo production modules for general purpose transport applications.

Solution method:
Nested 3-point Newton-Cotes quadrature routines are used to compute effective multigroup cross sections averaged over space, temperature and relative scattering angle.

Running time:
HPLAS consists of six cross section processor modules which average 2 min. each of CRAY-1S time to compile a 10 group, 5 region plasma cross section set.
