Abstract:
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 6.5<=alfa<=80 and densities (1.5 10^8<=n<= 7 10^9 cm−3) within a short duration (25 s) compatible with
the ATHENA antihydrogen production cycle.
