1970-2014: From Space Ion Thrusters to Nano-Tools
In the 1970’s, Albert Crewe demonstrated with scanning transmission electron microscopy that field emission sources allowed spectacular improvement (i.e., atomic resolution) in the field of electron microscopy [1]. Several groups in the USA, Great Britain, and France began to work on point ion sources in order to bring similar improvements to ion instruments, especially to secondary ion mass sp...
متن کاملEmissive Membrane Ion Thrusters and Their Applications
The mechanism of operation of a new thruster concept that utilizes solid-state ionic membranes to convert molecules into ions and transmit them to a surface from which they can be extracted into energetic beamlets thereby producing thrust is described. Results of recent experiments are used to estimate the performance of the thruster and the masses of various components required for it to perfo...
متن کاملFundamental Ion–surface Interactions in Plasma Thrusters
Ion thrusters offer the potential to enable many future interplanetary robotic missions presently under consideration by NASA. To realize the benefits offered by these low thrust devices, the sputtering mechanisms that are responsible for the degradation of thruster components over time must be well understood. Predictions of thruster life depend directly on the material removal rates from thru...
متن کاملApoptosis: from Signalling Pathways to Therapeutic Tools
Apoptosis or programmed cell death is a gene regulated phenomenon which is important in both physiological and pathological conditions. It is characterized by distinct morphological features including chromatin condensation, cell and nuclear shrinkage, membrane blebbing and oligonucleosomal DNA fragmentation. Although, two major apoptotic pathways including 1) the death receptor (extrinsic) and...
متن کاملErosion Rate Diagnostics in Ion Thrusters Using Laser-induced Fluorescence*
fio = atomic transition oscillator strength g = linewidth distribution function, sec We have demonstrated the use of laser-induced flug = energy-averaged Gaunt factor orescence (LIF) to monitor the charge-exchange ion 9i = degeneracy for atomic level i erosion of the molybdenum accelerator electrode in h = Planck's constant, J sec ion thrusters. This real-time, nonintrusive method h = Planck's ...
