From our previous research, we have successfully produce MeV proton beam by 1Hz repetition rate stabely from the interaction between the femto-second TW laser with solid target. Produced proton beam exhibits lower emittance. The number of proton beam is 10. However, it shows large divergence angle of 10 degree. The energy spectrum exhibits 100% energy spread. These are problematic for some specific applications. In this study we transported the laser-driven proton beam with permanent quadrapole magnet for the future application. We successfully obtain focused proton beam as well as the monochromatic proton beam. Those spatial distribution at the focus point as well as the spectral information is well reproduced by the montecalro simulation.
