I did not know about this device so I did a quick research: it's essentially an optimised version of early plasma devices that use instabilities to create a very compact, dense structure that can reach really high ion temperatures. The main problem I see is that this structure is very short-lived: on the order of 10 nanoseconds. These devices existed for a long time and have been used as X rays or neutron sources but not for fusion power. LPP have explained the exact machanism at the basis of the DPF fusion and have optimised the radiation losses and electron heating to reach higher temperatures but from this to claiming viable fusion power is quite a stretch.
