摘要：
The construction and operation of a Penning ion trap is described in which the trapping field is provided by a cladded NdFeB permanent magnet. Studies with atomic ions show that the trap can provide stable ion confinement for extended periods (greater than or similar to100 ms) making it suitable for use in a wide variety of applications. Use of the trap to measure the lifetime of excited SF(6)(-)* and C(7)F(14)(-)* ions produced in Rydberg atom collisions is briefly discussed. (C) 2002 American Institute of Physics.
