In this paper, we present multiband optical polarimetric observations of the very-high energy blazar PKS 2155−304 made simultaneously with a HESS/Fermi high-energy campaign in 2008, when the source was found to be in a low state. The intense daily co... Read More about Particle acceleration and magnetic field structure in PKS2155-304: optical polarimetric observations.
