European Interest in Inertial Fusion Rises

July 7, 2008

Although the French nuclear weapons program is building a laser facility (LMJ) comparable to the U.S. National Ignition Facility (NIF), European civilian energy officials have limited their interest in inertial fusion to maintaining a "watching brief." As inertial fusion ignition in NIF and possibly LMJ nears, and in recognition of growing worldwide interest in the concept of "fast ignition" (see, e.g., FPNs 05-21 and 06-34), momentum is building for the possible construction in Europe of a laser facility called "HiPER" which would combine a "long-pulse" 200 kJ compression laser and a 70 kJ "short-pulse" laser for fast ignition.

A 2-year design study of HiPER has recently been completed by a group of scientists from about a dozen European countries under the direction of Mike Dunn of the UK's Rutherford Laboratory. The conclusions of this study were deemed sufficient to include HiPER in the European roadmap for future large-scale science facilities. A 3-year "preparatory phase" project is now planned, aimed at preparing for an additional 3-year 'detailed definition and design phase" leading to possible construction start in 2014.
