Simulation of narrow column 3D detectors – search for gain
The 3D detectors with narrow and highly doped columns are most likely candidates for 3D devices with gain, similar to array of solid-state proportional wire tubes. 3D detectors with junction electrodes – n+ columns of <=1 um width could lead to gain depending on the width of the doping profile. Some initial performance simulation of such devices was performed identifying key design elements when single sided processing is used. The tip of the junction electrode is the area of peak field and is the reason for non-homogenous gain across the device. This leads to implications to timing performance of the devices the gain however allows the use of thinner devices for the same collected charge making detectors with smaller capacitance possible. Such detector would also benefit from smaller clusters, better efficiency hence extending the radiation tolerance beyond present designs. The simulations result of timing and charge collection efficiency will be presented.
