Title: Probing the Temperature Profile of Energy Production in the Sun

Abstract

The particle kinetic energies of thermonuclear pp fusion in the Sun (Gamow energy) produce small changes in the energies of pp solar neutrinos relative to those due only to exothermal energetics. This effect may be observable via the unique tools of the LENS solar neutrino detector. The temperature profile of energy production in the Sun may thus be directly probed for the first time.

  • The flux of neutrinos originating from cosmic ray interactions with matter in the Sun has been calculated based on Monte Carlo models for high energy particle interactions. The resulting flux at the Earth (within the Sun{close_quote}s solid angle) is higher than the corresponding one from cosmic ray interactions with Earth{close_quote}s atmosphere. The smallness of the absolute rate, however, precludes it as a practical {open_quote}{open_quote}standard candle{close_quote}{close_quote} for neutrino telescopes and limits neutrino oscillation searches. On the other hand, it facilitates dark matter searches based on neutrinos from neutralino annihilation in the Sun. {copyright} {ital 1996 The American Physical Society.}
  • The use of an exponential form of the temperature profile in producing wells will increase the estimate of tubing elongation and make the estimate more accurate. Tubing elongation is currently often calculated from temperature changes estimated from linear temperature profiles. The paper describes tubing elongation, elongation comparison, applications, and an example calculation.
  • Production and transport processes of the H{sup 0} atoms are numerically simulated using a three-dimensional Monte Carlo transport code. The code is applied to the large JAEA 10 ampere negative ion source under a Cs-seeded condition to obtain a spatial distribution of surface-produced H{sup -} ions. In this analysis, we focus on the effect of the energy relaxation of the H{sup 0} atoms at the wall on the H{sup -} ion production from the H{sup 0} atoms. The result indicates that, by considering the energy relaxation of the H{sup 0} atoms at the wall, the production profile of the surface-producedmore » H{sup -} ion is well reflected in the production profile of the H{sup 0} atom production.« less
