“what they’ll have learned from working with the tungsten will help them keep the Be erosion to manageable levels.”
This is likely to be troublesome. Berillium is usually considered a poisonous material, and its utilisation is subject to nuclear-grade regulations in the EU (I dont’ know about USA). For example, QinetiQ in the UK sells its own know-how in safe (?) berillium machining; it relies on decades of nuclear military expertise at Atomic Weapon Establishment, Aldermaston. Inclusion of berillium coating in future Plasma Focus is far from trivial: costs may be skyrocketing.
