Abstract
A novel two stage mass filter where the first stage operates in DC/RF mode and second in RF only mode is proposed. This design can be characterized by very high mass resolution and may not require high precision mechanical and electronic design. An ion detector by integrating a VLSI chip with a Faraday cup is described. Extremely low biasing currents, differential and narrow frequency band operation resulted in significant improvement of the signal to noise ratio.
