X-ray differential absorption microanalysis is presented as a technique for trace element analysis of hydrated biological specimens of about 0.1-5 μm thickness. For the study of the light elements (Z≲20), the absorption technique minimizes the rad

The delayed-gamma neutron activation facility at Brookhaven National Laboratory was originally calibrated using an anthropomorphic hollow phantom filled with solutions containing predetermined amounts of Ca. However, 99{percent} of the total Ca in th

A Fourier transform holographic microscope with an anticipated resolution of better than 100 nm has been built. Extensive testing of the apparatus has begun. Preliminary results include the recording of interference fringes using 3.6-nm X-rays. The m

The scanning transmission soft X-ray microscope (STXM) that has been under development at the National Synchrotron Light Source [H. Rarback et al., Rev. Sci. Instr. 59 (1988) 52] has been substantially ungraded for operation with the X1 undulator [C.

An undulator-based beamline was built and commissioned at the National Synchrotron Light Source to provide tunable coherent radiation in the 200–800 eV range. The low emittance of the storage ring means that the undulator source has high brightness

There are two central motivations for developing new scientific methods. One is, of couse, to accomplish what established methods cannot. A second is for comparison: To verify the conclusions of established methods. That is, are results obtained by o

Soft x-rays are attractive for microscopy because they tend to be less damaging to specimens than charged probes. In addition their interactions with specimens can result in element-specific information and the penetration depth is adjustable by choi

Rats and chicken embryos were imaged in vivo with a prototype multiple energy computed tomography (MECT) system using monochromatized X-rays from the X17 superconducting wiggler at the National Synchrotron Light Source (NSLS). The CT configuration co
