Position and mass determination of multiple particles using cantilever based mass sensors

Mass and position determination of attached particles on cantilever based mass sensors.

An analytical expression relating mass and position of a particle attached on a cantilever to the resulting change in cantilever resonant frequency is derived. Theoretically, the position and mass of the attached particle can be deduced by combining measured resonant frequencies of several bending modes. This finding is verified experimentally using a microscale cantilever with and without an a...

Fabrication of cantilever based mass sensors integrated with CMOS using direct write laser lithography on resist

A CMOS compatible direct write laser lithography technique has been developed for cantilever fabrication on pre-fabricated standard CMOS. We have developed cantilever based sensors for mass measurements in vacuum and air. The cantilever is actuated into lateral vibration by electrostatic excitation and the resonant frequency is detected by capacitive readout. The device is integrated on standar...

Mass Determination in Events with Multiple Missing Particles

Decays that include multiple particles that interact only weakly and gravitationally arise in the Standard Model of particle physics, but are especially relevant to Supersymmetry models and to dark matter theories. Collider events that lead to such decays cannot be fully reconstructed from detector data, and they call for a new reconstruction method. This paper describes a novel method for the ...
