Description
Full 3-dimensional device simulations have been carried on the new BNL 3D-Trench electrode detectors (or Independent Coaxial Detector Array (ICDA)). The full 3D simulations confirmed the conclusions from previous 1D simulations: the electric field in the 3D-Trench electrode detectors is much more homogeneous and no saddle points in electric potential as compared to the standard 3D detectors with column electrodes; the full depletion voltage and electric field can be greatly reduced if the trench electrode is set and the junction electrode --- in the case of coaxial arrangement, they can be even smaller than those in a 2D detector with a thickness the same as the electrode spacing in the 3D-Trench electrode detectors. Mask design has been completed, and the detector processing will soon be started.
