SUMMARY:Turbulence and Particle Acceleration in Solar Flares
DESCRIPTION:Turbulence and Particle Acceleration in Solar Flares\nProf. Lyn
 dsay Fletcher\n\nA solar flare involves the conversion of magnetic energy 
 stored in the coronal magnetic field into the kinetic energy of thermal an
 d non-thermal particles, mass motion, and radiation. How this happens rema
 ins a central question in solar physics. A particular long-standing puzzle
  is how such a high fraction of the stored magnetic energy - up to a half 
 - arrives in the kinetic energy of accelerated non-thermal particles. In t
 his talk I will present an observational overview of solar flares with an 
 emphasis on accelerated particles, discuss some ideas and constraints on p
 article acceleration, and present some new observations of the possible ro
 le of plasma turbulence in the acceleration process.\n
