Stand-alone microprobe at Livermore

PDF Version Also Available for Download.

Description

Lawrence Livermore National Laboratory (LLNL) and Sandia National Laboratories/California have jointly constructed a new stand-alone microprobe facility. Although the facility was built to develop a method to rapidly locate and determine elemental concentrations of micron scale particulates on various media using PIXE, the facility has found numerous applications in biology and materials science. The facility is located at LLNL and uses a General Ionex Corporation Model 358 duoplasmatron negative ion source, a National Electrostatics Corporation 5SDH-2 tandem accelerator, and an Oxford triplet lens. Features of the system include complete computer control of the beam transport using LabVIEW<sup>TM</sup> for Macintosh, computer ... continued below

Features of the system include complete computer control of the beam transport using LabVIEW<sup>TM</sup> for Macintosh, computer controlled beam collimating and divergence limiting slits, automated sample positioning to micron resolution, and video optics for beam positioning and sample observation. Data collection is accomplished with the simultaneous use of as many as four EG&G Ortec IGLET-X<sup>TM</sup> X-Ray detectors, digital amplifiers made by X-Ray Instruments and Associates (XIA), and LabVIEW<sup>TM</sup> for Macintosh acquisition software.
