摘要：

A new design for the Ge bolometers of the EDELWEISS project is described here, based on innovative interleaved charge collection electrodes with high background discrimination capabilities. The measured surface event rejection is compatible with WIMP sensitivity levels down to 10(-) 9 picobarn (pb). Use of interleaved electrodes on the overall surface of the Ge crystal, including its lateral surface, results to a high fiducial volume of the order of 80%. Electronic setup is fairly simple with a total of five JFET based read-out amplifiers, one for the NTD-Ge heat channel and four for the ionization signal. Fabrication process is quite simple and the design is easily scalable to higher mass bolometers (1 kg Ge crystal), making it very appealing for the future 1 ton scale EUREKA Dark Matter experiment.
