We have attempted to observe the Andreev reflection of a beam of ballistic quasiparticle excitations as it impinges on a static B-A phase interface. The beam is created, and the Andreev reflected component measured, by the quasiparticle equivalent of a black-body radiator. The A-phase is stabilized at low temperature and pressure by a magnetic field which is generated by a miniature superconducting solenoid, situated next to the radiator orifice and which provides the necessary 0.34 T field in a small, localized region. Preliminary results indicate that we can observe Andreev reflection both from the high-field distorted B-phase energy gap and from the larger equatorial A-phase energy gap. |
