The plasma neutralizer (PN) could be an attractive upgrade for the Neutral Beam Injection (NBI) system of the International Thermonuclear Experimental Reactor (ITER). A multicusp magnetic trap with microwave discharge plasma generation was proposed as a scheme for PN.The experimental investigation of the scheme is undertaken in Kurchatov Institute.

We apply canonical Poisson-Lie T-duality transformations to bosonic open string worldsheet boundary conditions, showing that the form of these conditions is invariant at the classical level, and therefore they are compatible with Poisson-Lie T-duality. In particular the conditions for conformal invariance are automatically preserved, rendering also the dual model conformal. The boundary conditions are defined in terms of a gluing matrix which encodes the properties of D-branes, and we derive the duality map for this matrix. We demonstrate explicitly the implications of this map for D-branes in two non-Abelian Drinfel'd doubles.
