	abstract = {<p>Our group ASACUSA-MUSASHI has established an efficient way for accumulating antiprotons in the cusp trap, a combination of an anti-Helmholz superconducting coil and a multi-ring electrode trap. The last piece for synthesizing antihydrogens in the cusp trap is positron. We have developed a compact system to effectively accumulate positrons based on N 2 gas-buffer scheme with a specially designed high precision cylindrical multi-ring electrode trap. Millions of positrons were accumulated in the pre-accumulator just using polycrystalline tungsten moderators. The accumulated positrons were transported as a pulsed beam via three guiding coils and caught in the cusp trap under cryogenic and ultra high vacuum conditions without serious loss. Confinement of two kinds of numerous antiparticles, e.g., 10 8 positrons and 10 7 antiprotons, in the cusp trap becomes feasible.</p>

	abstract = {A new scheme is proposed for synthesizing antihydrogen by trapping positrons at the centre of a field consisting of a magnetic quadrupole and an electric octupole. It is expected that the total electric field of this octupole with the space charge of the trapped positrons themselves will be strong enough to confine antiprotons inside the positron cloud, where the two particle species will combine to produce antihydrogen atoms spontaneously via radiative recombination. Furthermore, a numerical simulation has revealed that a considerable fraction of antihydrogen atoms in low-field-seeking states formed at 5 K near the centre of the trap may be transported as a 99\% polarised beam and focused 1 m from the trap centre with ~ 0.3\% efficiency, corresponding to an enhancement in beam intensity by a factor 30.},
