内容記述 |
We are studying the very short ion bunches using a Laser Plasma RF Ion Source (LaPRIS). This device generates ion bunches by a pulsed gas jet irradiated with a femtosecond laser and acceleration with an RF electric field synchronized with the gas jet. In the test experiment of air ionization by femtosecond laser, the ionization in air at 0.5 Pa was confirmed using Micro Channel Plate as an ionized particle detector and the laser intensity at the focal point was estimated to be approximately 8×10¹³ W/cm². A beam test of LaPRIS also has been carried out. In the experiment, we used a synchronized trigger system that combined hydrogen gas, RF bursts, and laser pulses at a repetition rate of 5 Hz. Although a clear ion beam signal has not yet been observed, possibly due to insufficient laser focusing, the experimental setup is now ready for testing. Multi-particle Simulations using OPAL suggest that LaPRIS can produce beams with low emittance and short bunch length under low current conditions. These results indicate that the system has strong potential for applications in precision nuclear physics. |
