    "abstract": "A large admittance sector cyclotron filled with LiH wedges surrounded by\nhelium or hydrogen gas is explored. Muons are cooled as they spiral\nadiabatically into a central swarm. As momentum approaches zero, the momentum\nspread also approaches zero. Long bunch trains coalesce. Energy loss is used to\ninject the muons into the outer rim of the cyclotron. The density of material\nin the cyclotron decreases adiabatically with radius. The sector cyclotron\nmagnetic fields are transformed into an azimuthally symmetric magnetic bottle\nin the center. Helium gas is used to inhibit muonium formation by positive\nmuons. Deuterium gas is used to allow captured negative muons to escape via the\nmuon catalyzed fusion process. The presence of ionized gas in the center may\nautomatically neutralize space charge. When a bunch train has coalesced into a\ncentral swarm, it is ejected axially with an electric kicker pulse.",
