Vibration and shock reliability of MEMS: modeling and experimental validation

Herbert Shea, Robert Andrew Lockhart, Subramanian Sundaram, Maurizio Tormen

A methodology to predict shock and vibration levels that could lead to the failure of MEMS devices is reported as a function of vibration frequency and shock pulse duration. A combined experimental–analytical approach is developed, maintaining the simplici ...

ESD testing and combdrive snap-in in a MEMS tunable grating under shock and vibration

Herbert Shea, Robert Andrew Lockhart, Subramanian Sundaram, Maurizio Tormen

This work describes a method for tracking the dynamics of electrostatic discharge (ESD) sensitive MEMS structures during ESD events, as well as a model for determining the reduced combdrive snap-in voltage under vibration and shock. We describe our ESD tes ...

SHOCK IMPACT OF HIGH ENERGY/INTENSITY BEAMS WITH MATTER AND HIGH ENERGY DENSITY PHYSICS

Juan Blanco Sancho, Rudiger Schmidt

The purpose of this study is to assess the damage caused to the equipment (beamdump, collimators etc) in case of an accident involving full impact of the LHC beam. First, the FLUKA code [1] is used to calculate the proton energy loss in solid carbon and th ...

Scanning near-field optical microscope based on double-resonant fiber probe montage and its operation in liquids - art. no. 67282D

Giovanni Dietler, Kanat Dukenbayev

The operation of the scanning near-field optical microscope based on the double-resonant montage of a fiber probe onto the tuning fork (working frequency of the latter, that is 32 kHz, coincides with the second resonance frequency of the bending oscillatio ...

Timescales of shock processes in chondritic and martian meteorites

Philippe Gillet, Pierre Beck

The accretion of the terrestrial planets from asteroid collisions and the delivery to the Earth of martian and lunar meteorites has been modelled extensively(1,2). Meteorites that have experienced shock waves from such collisions can potentially be used to ...
