Abstract

We describe the construction of a novel compact Penning trap from strong permanent magnets for trapping light ions. Our cylindrically symmetric, iron-free magnetic configuration allows fully analytical treatment, is easy to handle and to optimize. The magnetic field inhomogeneity is less than 1% in a volume of 1 cm3 at 0.7 T. The stored H+ and H +2 ions in this trap are detected electrically by the rf absorption method. The charge density, total number and storage time of the trapped ions are measured.
