A magnetic trap for antihydrogen confinement
نویسندگان
چکیده
The goal of the ALPHA collaboration at CERN is to test CPT conservation by comparing the 1S–2S transitions of hydrogen and antihydrogen. To reach the ultimate accuracy of 1 part in 10, the (anti)atoms must be trapped. Using current technology, only magnetic minimum traps can confine (anti)hydrogen. In this paper, the design of the ALPHA antihydrogen trap and the results of measurements on a prototype system will be presented. The trap depth of the final system will be 1.16 T, corresponding to a temperature of 0.78K for ground state antihydrogen. r 2006 Elsevier B.V. All rights reserved. PACS: 36.10. k; 34.8DLx; 52.20Hv

Simulations of plasma confinement in an antihydrogen trap
The three-dimensional particle-in-cell 3-D PIC simulation code WARP is used to study positron confinement in antihydrogen traps. The magnetic geometry is close to that of a UC Berkeley experiment conducted, with electrons, as part of the ALPHA collaboration W. Bertsche et al., AIP Conf. Proc. 796, 301 2005 . In order to trap antihydrogen atoms, multipole magnetic fields are added to a conventio...
متن کاملFirst Attempts at Antihydrogen Trapping in ALPHA
The ALPHA apparatus is designed to produce and trap antihydrogen atoms. The device comprises a multifunction Penning trap and a superconducting, neutral atom trap having a minimum-B configuration. The atom trap features an octupole magnet for transverse confinement and solenoidal mirror coils for longitudinal confinement. The magnetic trap employs a fast shutdown system to maximize the probabil...
متن کاملEffects of extreme magnetic quadrupole fields on penning traps and the consequences for antihydrogen trapping.
Measurements on electrons confined in a Penning trap show that extreme quadrupole fields destroy particle confinement. Much of the particle loss comes from the hitherto unrecognized ballistic transport of particles directly into the wall. The measurements scale to the parameter regime used by ATHENA and ATRAP to create antihydrogen, and suggest that quadrupoles cannot be used to trap antihydrogen.
متن کاملThree designs for a magnetic trap that will simultaneously confine neutral atoms and a non-neutral plasma
Three trap designs are proposed for the simultaneous confinement of neutral atoms and a non-neutral plasma in close proximity. One design uses axially symmetric static magnetic fields with a magnetic minimum in a ring around the trap axis. Axial symmetry is required for confinement of the rotating non-neutral plasma, and the magnetic minimum traps the neutral atoms. The second design uses a rot...
متن کاملStability of a charged particle in a combined Penning-Ioffe trap.
The axial symmetry of a familiar Penning trap is broken by adding the radial magnetic field of an Ioffe trap. Despite the resulting loss of a confinement theorem, stable orbits related to adiabatic invariants are identified, expressions are given for their frequencies, and resonances that must be avoided are characterized. It seems feasible to experimentally realize the new Penning-Ioffe trap t...
