The behavior of test particles in a filamentary current sheet, which was proposed as a model for fragmentary energy release, is investigated. An analytic current sheet model, with antiparallel external fields, is used, and a perpendicular electric field is added. It is demonstrated that the perpendicular electric field can accelerate particles efficiently and that the multiple X-line configuration permits higher particle energies than a single X-line configuration for similar plasma parameters. Taking typical plasma parameters of impulsive flare regions in the lower solar corona, many of the observed particle characteristics can be reproduced. The relevance of the considered process to particle acceleration in galactic and extragalactic plasmas requires further study.
