GEKKO XII GLASS LASER SYSTEM 

 Osaka University 



"Big Science" Descriptor : Inert ial-confineraent fusion 



Description of Facility/Instrument ; GEKKO XII is a 12-beani 20 

 kilojoule/40 tetrawatts neodymium glass laser system with 

 two separate target experimental rooms. Beams are switched 

 to the two experimental areas, permitting overlapping experi- 

 ments. Target chamber 1 is equipped for uniform irradiation 

 by 12 beams at 1.053 microns or 0.526 microns of spherical 

 targets. Target chamber 2 is equipped to irradiate flat 

 plate targets in a 100-degree cone. The system with target 

 chamber 1 is roughly comparable to the OMEGA laser system at 

 the Unviersity of Rochester.

Present International Cooperation 



Natlonality(s) of Ownership : Japan 

 Nationality(s) of Operational Funding : Japan 

 Nationality(s) of Management Staff : Japan 

 Nationality(s) of Researchers : mostly Japan 



Potential for Future International Cooperation ; Probably large, 

 although U.S. classification rules and policy on cooperation 

 in inertial fusion would severely Inhibit cooperation from 

 U.S. Inertial Fusion Program laboratory groups.
