Abstract
Detectors fitted with interleaved collection electrodes offer a promising solution to the problem of surface event rejection in cryogenic Ge detectors for dark matter search. Detector design and modeling are discussed, based on computer simulations of the collection field and on pulse-shape analysis of the ionization signals. Test experiments with a prototype detector are presented in a companion paper by X. Defay et al. in this conference.
