Abstract:
High efficient detectors for ultracold neutrons (UCN) must be developed for the new high flux neutron source Forschungsreaktor München II (FRM II). On silicon PIN diodes 76 μg/cm2 58Ni was deposited as a UCN reflector. On this 100 double layers of natTi (4.7 μg/cm2) and 6LiF (1.8 μg/cm2) were deposited to function as a UCN converter. On top of this, 33 double layers of natTi (3.4 μg/cm2) and 6LiF (0.92 μg/cm2) were condensed in addition to provide sensitivity to very low-energy UCN. Finally, 6.0... »
