Recent a project called Laser plasma Proton Accelerator (LAPA) is approved by MOST in China. A prototype of laser driven proton accelerator (1~15MeV) based on the PSA mechanism and plasma lens is going to be built at Peking University in the next five years. It can be used for the applications such as cancer therapy, plasma imaging and fast ignition for inertial confine fusion. The recent progress of LAPA is reported here.

Generally the beam emittance can be measured by different Emittance Measurement Units (EMUs), such as the pepper-pot device, the slit-wire type facility and the Allison scanner. However, for a microsecond single-shot ion beam, the pepper-pot device is a suitable choice because of its cut-off single-shot technique without any time-consuming step. A pepper-pot based beam current & profile measurement device, which is a combination of Faraday cup technique and pepper-pot measurement facility, was developed at PKU. It consists of a main Faraday cup with a pepper-pot mask at its bottom, and a Faraday cup array locating 3 mm away from the pepper-pot mask. This device has been tested at the PKU LEBT test bench and the measurement results are consistent with the results acquired by the Allison scanner. By replacing the Faraday cup array with a fluorescent screen and a CCD camera, this device becomes a facility that not only has the ability to measure the total beam current and the beam profile, but also has the capability to measure the beam emittance for CW or pulsed ion beams. Details will be presented in this paper.
