New record fusion yields as FoFu-1 shows rapid scaling

Fusion Yield Oct 2011

FF-1 tops its previous ‘personal best’ record for fusion yield, achieves nearly I5 scaling with current We are happy to report that FF-1 achieved a new record with the production of 150 billion neutrons in two shots on October 10.  For some time during the recent post-upgrade shakedown, the device had not produced over 100 billion…

New record beams bode well for applications


FF-1 Record for ion beam current—near 300 kA With our greater repeatability has come a reduced variability and larger current in the beam measured by the upper Rogowski coil (URC) and by our photo-multiplier tubes (PMTs), which measure hard X-rays generated by the electron beam. Our highest current beams, seen twice on May 11, have current of…

Increased repeatability for science, commercialization

Murali fights the asimmetry

Focus Fusion-1 achieves much greater repeatability, closer to theoretical predictions Major improvement in repeatability of fusion yield and beam production. Repeatable fusion yield is now within a factor of 4 of predictions. Clues found from data and simulation on improving filamentation, ending the early-beam problem and boosting yield up to predictions. LPP researchers have made…

Successful 45 kV firing sets stage for key fusion tests

Re-inspection of a mirror polish

New switch design, after tweaking, fired successfully all the way up to 45 kV Backgrounder: Find out why these upgraded switches are so important to LPP’s breakthrough fusion research with this overview from the Focus Fusion Society.  Or check out this recap from NextBigFuture. LPP’s long-awaited new switch design was successfully tested in mid-May, after some improvements…

Fighting the early beams


Our research team is continuing to examine the causes of the shot-to-shot variability that affects FF-1 (as it does all DPFs to date) and the reason that we, in general, are getting lower fusion yields than our theory expects. Previously we have traced this to a too-early generation of the electron and ion beams that…
