Abstract: A gain of a factor of about 5 in the total peak current and an in-creased amount of higher states ions were observed when the laser pasma was trans-ported through magnetic bottle fields.When the RF discharge was added to the laser plasma ion source to further ionize the laser plasma,the total peak current increased from 0.53mA to 1.4mA.In addition,test results on a laser source coneerning the iufluence of supcort gases upon the laser-plasma are described in detail as well.
