The present invention is a system and method for providing a charge detector that utilizes small feedback capacitors in a low-noise, high-gain, system that combines a differential topology in a solid-state amplifier implemented in a complementary metal-oxide semiconductor (CMOS) process with active reset, thereby achieving high dynamic range and robust operations. A custom optoelectronic system is used to measure gain, and while operating at a sampling frequency of 10 kHz, the active reset extends the dynamic range of the charge detector.

Solid-state charge detector

A combination of electrodes that are cylindrical and an asymmetric arrangement of cylindrical and planar electrodes are used to create electric fields that compensate for toroidal curvature in a toroidal ion trap, the design lending itself to high precision manufacturing and miniaturization, converging ion paths that enhance detection, higher pressure operation, and optimization of the shape of the electric fields by careful arrangement of the electrodes.

Toroidal ion trap mass analyzer with cylindrical electrodes

A coaxial hybrid ion trap that uses two substantially planar opposing plates to generate electrical focusing fields that simultaneously generate at least two different types or shapes of trapping regions, wherein a first trapping region is a quadrupole trapping region disposed coaxially with respect to the opposing plates, and wherein a second trapping region is a toroidal ion trap having a toroidal trapping region that is simultaneously created around the quadrupole trapping region.
