Filed:

Feb 25, 2008

Appl. No.:

12/036999

Inventors:

Samuel E. Tolley - Springville UT, US
Daniel E. Austin - Mapleton UT, US
Aaron R. Hawkins - Provo UT, US
Edgar D. Lee - Highland UT, US

Assignee:

Brigham Young University - Provo UT

International Classification:

B01D 59/44
H01J 49/00

US Classification:

250292, 250281, 250282, 250287, 250290

Abstract:

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.

Appl. No.:

13/589988

Inventors:

Daniel E. Austin - Mapleton UT, US
Nicholas R. Taylor - Richland WA, US

Assignee:

Brigham Young University - Provo UT

International Classification:

H01J 49/22

US Classification:

250292, 250281, 250282, 250290, 250291, 250396 R, 250397, 250396 ML

Abstract:

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.

Abstract:

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.
