Résumé
We propose that two-channel orbital Kondo ``spin'' 1/2 conductance can be
measured in a quantum dot at Coulomb Blockade with an odd number of electrons
with contacts in a pillar configuration, if an orthogonal magnetic field
induces an appropriate level crossing. At the zero-temperature strong coupling
fixed point the conductance reaches the unitarity limit with a non-Fermi liquid
sqrt(T)-law.
