Neutron production from feedback controlled thermal cycling of a pyroelectric crystal

The LLNL Crystal Driven Neutron Source is operational and has produced record ion currents of ∼ 10 nA and neutron output of 1.9 ( ± 0.3 ) × 10 5 per thermal cycle using a crystal heating rate of 0.2 ° C ∕ s from 10 to 110 ° C . A 3 cm diameter by 1 cm thick Li Ta O 3 crystal with a socket secured fi...
