Si-EDS has sufficient geometric collection efficiency and quantum efficiency to operate with the picoampere to low nanoampere beam currents of the FEG-SEM. Measuring signals in the range of picoamperes (10-12 amperes), at levels thought impossible only a few years ago, the innovative IC helps Siemens Medical Solutions to design CT systems with the minimum of X-ray necessary, providing significant patients benefits due to vastly reduced patient exposure. These CS300X family fulfills these requirements, with input leakage of only 100 picoamperes and an input offset voltage of only five microvolts (CS3003/CS3013; 10 microvolts in the CS3004/CS3014) with drift of 0. |
