Description

A laser ion source can provide stable intense heavy ion beams with relatively simple structure. Recently, solenoid confinement technique was developed and applied to the operating laser ion sources. By introducing solenoid, supplied ion beam current can be enhanced and adjusted for the applications. However, it is known that the expanding laser plasma confined by a solenoid filed becomes unstable in a certain magnetic field region. To investigate the unstable condition further, it is essential to quantify the instability. In this study, we propose the most appropriate method to evaluate plasma instability. The validity was evaluated by comparing five methods, variation of maximum value, variation of integral value, variation of half width, variation of half value width divided by maximum value, integral value of difference from average waveform. The detailed comparison discussion will be given at the presentation.
