A plasma lens for the CERN Antiproton Collector scaled from model and experiment

The developmental work on plasma lens prototypes for antiproton collection is summarized. The antiproton yield with a plasma lens is estimated. Results of the latest z-pinch model describing the plasma dynamics in such a lens are presented. The scaling of the final plasma lens parameters is based on both model and measurement. Destruction rates of insulator tube and electrodes have been measured. A final set of parameters is proposed. Scaling from the experimental and numerical results shows that for the final Antiproton Collector plasma lens a new pulse generator is required, featuring a cycle time of more than 30 mu s (twice that of the present test generator) and a stored pulse energy of more than 25 kJ at 10-13-kV charging voltage. >
