Abstract / Description:An observation of a clear dependence of antihydrogen production on positron plasma shapes is reported. For
this purpose a plasma control method has been developed combining the plasma rotating-wall technique with
a mode diagnostic system. With the help of real-time and nondestructive observations, the rotating-wall parameters
have been optimized. The positron plasma can be manipulated into a wide range of shapes aspect
ratio 6.580 and densities 1.5108n7109 cm−3 within a short duration 25 s compatible with
the ATHENA antihydrogen production cycle.
