According to one embodiments, an ion source connected with a vacuum-exhausted downstream apparatus is provided. The ion source includes a vacuum chamber which is vacuum-exhausted, a target which is set in the vacuum chamber and generates ions by irradiation of a laser beam, a transportation unit which transports the ions generated by the target to the downstream apparatus, and a vacuum sealing unit which seals the transportation unit so as to separate vacuum-conditions of the vacuum chamber side and the downstream apparatus side before exchanging the target set in the vacuum chamber.

Ion source

According to one embodiment, there is provided a laser ion source. The laser ion source includes a vacuum chamber which is vacuum-exhausted and in which a target is transported and set, a valve which is opened when the target is transported into the vacuum chamber and is closed except for the transportation, a target supply chamber which holds the target to be movable, and a transportation unit which transports to the vacuum chamber the target held on the target supply chamber while opening the valve after the target supply chamber is vacuum-exhausted while closing the valve.

Laser ion source

Provide an ion source for outputting ion beam with high purity of polyvalent positive ion. The ion sourceincludes: a targetfrom which electron and positive ion are generated by plasma formed by laserirradiation; a first power supply source (first voltage E) that sets an electric potential of the targethigher than that of a destination of the positive ion (corresponding to an acceleration channelin FIG.); and a second power supply source (second voltage E) that sets an electric potential of on a pass (corresponding to a filter electrodein FIG.) from the targetto the destinationhigher than that of the target

Test apparatusjudges a test item, and when carrying out a radio transmission characteristics test, communicates layersignals with mobile terminal apparatusto implement radio connection over CDMA radio interface and transmit a measurement signal. In transmitting the measurement signal, mobile terminal RLC control sectionnotifies RLC sectionof suspension of transmission of a signaling signal, and based on the notification, RLC sectionsuspends transmission of a signaling signal and transmits only the measurement signal. It is thereby possible to carry out the radio transmission characteristics test with constant transmission power without providing the mobile terminal apparatus with a function only required for the radio transmission characteristics test.
