Abstract: This invention provides a design to process a large range of detection beam current at low noise with a single detector. With such a design, the detection system can generate up to 1010 gain and maximum signal output at more than mini Ampere (mA) level. A condenser lens is configured to increase bandwidth of the detector that scan speed can be enhanced.
