In D-3He fusion power generation, an application of direct energy conversion is expected in which separation of charged particles is necessary. A cusp-type direct energy converter (CuspDEC) was proposed as a charge separation device, but its performance was degraded for a high density plasma. The goal of the present study is to establish an additional method to assist charge separation by using a nonlinear effect of a radio frequency (rf) electric field. Following to the previous study, we experimentally examine the effect of an rf field to electron motion in a CuspDEC device. Two ring electrodes were newly installed in a CuspDEC simulator and the current flowing into the electron collector located in the line cusp region was measured on an rf field application. The significant variation in the current was found, and an improvement of the charge separation can be expected by using the phenomenon appropriately.

As an energy recovery device for fast protons produced in D-3He nuclear fusion, secondary electron (SE) direct energy converter (SEDEC) was proposed in addition to traveling wave direct energy converter (TWDEC). Some protons passing through a TWDEC come into an SEDEC, where protons penetrate to a number of foil electrodes and emitted SEs are recovered. Following to a development of SE orbit control by magnetic field, dependence on incident angle of protons was examined to optimize structure of SEDEC. Based on a theoretical expectation, experiments were performed by changing incident angle of protons and variation in emission and energy recovery were measured. Both emission and energy recovery increased as the angle increased, and differences with theoretical expectation are discussed.

- ENHANCED ENERGY RECOVERY IN A SECONDARY ELECTRON DIRECT ENERGY CONVERTER THROUGH REDUCTION OF THE MAGNETIC MIRROR EFFECT
With an aim to improve the total efficiency of a D-(3) He nuclear fusion direct energy conversion system, a secondary electron direct energy converter (SEDEC) is proposed. The incident high-energy protons in an SEDEC penetrate a large number of foil electrodes aligned in the direction of the proton beam, and emitted secondary electrons are recovered. The results of the initial experiments showed that most of the secondary electrons flowed into anteroposterior electrodes and did not arrive at the electron collector located alongside and perpendicular to the direction of the proton beam. A magnetic field was introduced to push the electrons toward the electron collector, but it was not effective for energy recovery. This technical note analyzes the trajectories of electrons in the presence of the magnetic field and proposes and examines a revised arrangement of permanent magnets. The arrangement of the magnets along one side of the proton beam greatly improved the energy recovery; however, the recovery level was lower than that without magnets.

A traveling wave direct energy converter (TWDEC) is expected to be used as an energy recovery device for fast protons produced during the D-3He nuclear fusion reaction. Some protons, however, are not fully decelerated and pass through the device. A secondary electron direct energy converter (SEDEC) was proposed as an additional device to recover the protons passing through a TWDEC. In our previous study, magnetic field was applied for efficient secondary electron (SE) collection, but the SEs were reflected close to the collector due to the magnetic mirror effect and the collection was degraded. Herein, a new arrangement of magnets is proposed to be set away from the collector, and experiments in various conditions are performed. An appropriate arrangement away from the collector resulted in the improvement of SE collection.

- EXAMINATION ON PLASMA PRODUCTION AND ION HEATING FOR ELECTRIC PROPULSION USING A SINGLE HELICAL ANTENNA
A new structure of RP control of plasma for electric propulsion has been proposed With excitation characteristics of a helical antenna and propagation characteristics of waves with rotating field, both plasma production and ion heating will be expected simultaneously by employing a single helical antenna. Basic experiments to examine the proposed structure have been performed, showing consistent results with expected scenario.

- BASIC CHARACTERISTICS OF SECONDARY ELECTRON EMISSION FROM FOIL ELECTRODES FOR NEW ENERGY RECOVERY SCHEME OF HIGH ENERGY IONS IN AN ADVANCED FUSION
The new energy recovery method using secondary electron emission has been studied in order to improve energy recovery from high energy protons of fusion products in D-He-3 nuclear fusion generation. The model experiments were performed by using the tandem electrostatic accelerator and the basic characteristics were investigated. According to our results, for penetration aluminum is better as a target material than copper, H+ is better than He2+, and higher energy beam is better which agree with numerical calculations. A qualitative characteristic of secondary electron emission dependence on beam energy was also obtained.

Proposed is a new type of magnetoplasma thruster using one radio frequency system for both plasma production and ion heating. This is accomplished with a rotating field antenna consisting of a pair of antenna windings, which are fed by two radio frequency outputs with relative phase difference of -n to n. If the rotating field antenna excites, by a proper phasing, the fields polarized in left-hand sense with respect to the external magnetic field, the fields couple to slow ion cyclotron waves that accelerate ions at the ion cyclotron resonance. On the other hand, the right-hand polarized fields produced by opposite phasing do not couple with the slow waves and their energy goes to electrons via fast wave excitation and enhances ionization. It is experimentally verified that for hydrogen plasmas the density of produced plasmas and the temperature of heated ions change sinusoidally with the phase difference peaking at pi/2 and -pi/2, respectively, showing the ability to control power ratio of the ion heating to the plasma production by only changing the phase difference. At optimum condition, the exhaust velocity of ions corresponds to the specific impulse of 6000s. It is thus demonstrated that the use of the rotating radio frequency system provides novel controllability for the magnetoplasma thruster.

For the treatment of cancer using hyperthermia, high frequency electromagnetic fields are used to heat the cancer cells. These electromagnetic fields fall into two general frequency ranges, one relatively low, and the other in the microwave range. Both produce some side effects such as the heating of healthy cells or the impact on the body of invasive surgery required to expose deep-lying cells. To reduce these side reactions, the use of lower microwave frequencies with phase control was proposed. In this paper, we present a very basic study to prove the viability of the proposed scheme. This includes the selection of a suitable frequency, demonstration of localized heating using the selected frequency, and a three-dimensional numerical analysis of the electromagnetic fields involved. In the heating demonstration, a tissue-equivalent phantom made from agar was irradiated by phase-controlled electromagnetic waves from a pair of circular patch antennas operating at 430 MHz. This produced localized heating. The numerical analysis produced a field distribution that corresponded closely to the results from the heating experiment. It confirmed that the phase control technique for long-wavelength microwaves was effective in producing localized heating.
