	The accelerator-driven system (ADS) is discussed as one of the efficient device to transmute long-lived nuclides. For the efficient transmutation of the minor actinide (MA), precise prediction of neutronic performance of ADS is indispensable. The Transmutation Physics Experimental Facility (TEF-P) aimed at obtaining experimental data for the accuracy improvement of neutronics evaluation of MA-loaded ADS. The critical assembly installed in TEF-P operates below 500 watt to prevent the excessive radio activation of assembly. For the separation of low power beam from J-PARC intense proton accelerator, the meticulous low power beam extraction method from high power proton beam is required. The laser charge exchange method (LCE) is originally developed to measure the proton beam profile and can be applied to the beam separation device for TEF-P. The LCE device consists of bright YAG-laser and laser transport system with beam position controllers. We performed the stability tests for laser power and position of exposure by no proton beam condition. The further LCE tests using negative 3-MeV proton linac in J-PARC will be conducted. In this paper, present status of LCE tests is presented.

The accelerator-driven system (ADS) is discussed as one of the efficient device to transmute long-lived nuclides. For the efficient transmutation of the minor actinide (MA), precise prediction of neutronic performance of ADS is indispensable. The Transmutation Physics Experimental Facility (TEF-P) aimed at obtaining experimental data for the accuracy improvement of neutronics evaluation of MA-loaded ADS. The critical assembly installed in TEF-P operates below 500 watt to prevent the excessive radio activation of assembly. For the separation of low power beam from J-PARC intense proton accelerator, the meticulous low power beam extraction method from high power proton beam is required. The laser charge exchange method (LCE) is originally developed to measure the proton beam profile and can be applied to the beam separation device for TEF-P. The LCE device consists of bright YAG-laser and laser transport system with beam position controllers. We performed the stability tests for laser power and position of exposure by no proton beam condition. The further LCE tests using negative 3-MeV proton linac in J-PARC will be conducted. In this paper, present status of LCE tests is presented.
