Abstract
We have studied the energy gap of the Kondo Insulator SmB6 by means of transverse magnetoresistance measurements at temperatures down to 40m K and in magnetic fields to 50T. At 40 mK an inflection point in the t ransverse magnetoresistance is observed near 35T which may indicate th e closing of the gap and the onset of closed orbits.
