The UC Berkeley Paleomagnetism Lab features a superconducting rock magnetometer within a three-layer magnetostatic shield. The walk-in shield creates a low-field analytical and sample handling environment while the magnetometer is equipped with 3 very sensitive DC superconducting quantum interference devices (SQUIDs) to measure the remanent magnetization of earth and planetary materials. The lab is directed by Prof. Swanson-Hysell

The Zeiss EVO-10 Variable Vacuum SEM is available for general research and can be used for both secondary electron (SE) and backscattered electron (BE) imaging. Qualitative chemicalanalyses can be performed with a energy-dispersive X-ray detector (EDS). The SEM is also used for electron backscatter pattern (EBSP) and orientation imaging (OIM) as applied to analysis of preferred orientation.

Common Uses: Excellent for imaging surface morphology (texture), crystal structure, orientation and composition of samples in both thin section and free-standing mounts. For scheduling, please contact Tim Teague (tteague@berkeley.edu).

SEM Lab details:

  • Zeiss EVO Variable Vacuum Instrument -10
  • Tungsten filament
  • Large sample chamber with 9 position sample holder.
  • Variable pressure capable
  • Detectors:Secondary electron; Secondary electron VP; Backscatter electron
  • EDAX system for chemical analysis with silicon drift detector and thin window (detects down to Boron).
  • Electron Backscatter diffraction (EBSD) for crystal orientation measurement.
  • Carbon evaporator
  • Gold sputter coater

This laboratory is dedicated to the study of preferred orientation (texture) and anisotropy of polycrystalline materials. Various aspects are measurements, data analysis and interpretation. Applications include rocks, metals, polycrystalline films, ceramics, superconductors, biological specimens (bones, shells). The facilites are available to outside users on a recharge basis. Equipment includes X-ray pole figure diffractometer, EBSD SEM and sample preparation such as ion-beam thinner. The Texture Laboratory maintains software for quantitative texture analysis (BEARTEX) and provides introductions for texture analysis based on the Rietveld method from neutron diffraction data as well as synchrotron diffraction images.

XRD is used to identify and characterize crystal phases in powdered samples. Minerals and synthetic crystals produce characteristic x-ray patterns that can be compared with a database of known phases using analytical software. The department has a PANalytical X’Pert Pro diffractometer equipped with a Co x-ray tube and the very fast X’Celerator detector. The unit has a 15 position sample changer and a set of low background sample holders for samples as small as 1 milligram.

XRD Specs
• Panalytical X’Pert Pro
• 15 position sample changer
• X’Celerator fast detector 100x faster than scintillation counter
• Co tube
• Silicon and quartz zero background plates for samples down to 1mg.

The XRF is used for chemical analysis of a variety of materials including rocks, soils, cement, ceramics and archeological objects. For major elements (Na-Fe) 0.5g of sample is mixed with flux and fused into a glass disc. For trace element analysis 3g of powdered sample is pressed into a pill. Non-destructive trace element analysis is possible for such applications as archeology and art history. The department has a Philips PW2400 wavelength-dispersive x-ray fluorescence spectrometer with light element capability. The five crystals installed in the unit allow the analysis of elements O-U. The instrument also includes a fully automated 30 position sample changer for extended analysis acquisition time. They have a new Thermo QuantX energy- dispersive XRF, which is an excellent choice for non-destructive analysis of large objects and fast qualitative analysis of almost any type of material.

XRF Specs:
• Thermo Scientific Quant’x
• Bench top energy dispersive XRF with rhodium tube

XRF Prep Lab Specs:
• Ohaus Analytical Balance
• Air-gas Meker burner with platinum crucibles and mold for fused bead
• Hydraulic Powder Press
• 10 ton pill press
• Carbide Mortar& Pestal
• Spex pulverizer
