Abstract

In this paper, we describe a novel pulsed magnet, called Foil Coil, which can deliver a field transverse to the light propagation of more than 10 T over about 0.8 meters operating without cryogenic equipment. It has been designed for linear magnetic birefringence measurements. We report on testing the coil, and also show some physics data taken in vacuum during its commissioning in the framework of the BMV apparatus, with special attention to noise induced by the pulse itself. Finally, we compare the preliminary results obtained here, with data from the previous BMV coil.
