The proton linac installed in the Ibaraki Neutron Medical Research Center is used for production of the intense neutron flux for the Boron Neutron Capture Therapy (BNCT). The linac consists of the 3-MeV RFQ and the 8-MeV DTL. Design average beam current is 10mA. Target is made of Beryllium. First neutron production from the Beryllium target was observed at the end of 2015 with the low intensity beam as a demonstration. After the observation of neutron production, a lot of improvement s was carried out in order to increase the proton beam intensity for the real beam commissioning. The beam commissioning has been started on May 2016. The status of the commissioning is summarized in this report.

In the J-PARC acceletarors, maintenances should be minimized under high levels of radiation. An ultra high vacuum is required for the system in order to realize a long lifetime of the vacuum components. Materials of copper, stainless steel, titanium, alumina ceramics are to be finished as so to reduce the outgassing rate. The measurement of outgassing rate of titanium whose surface is chemically stable has the lowest value compared to any other materials examined so far.
