In March of this year, CHESS commissioned the Maia detector, a 384-pixel, energy-dispersive pixel array detector for x-ray fluorescence-based applications, especially XRF imaging.

The IPEI grants connect Ithaca City School District teachers with community partners in support of new ways to engage students while keeping the community involved.

The Macromolecular Diffraction Facility at the Cornell High Energy Synchrotron Source (MacCHESS) held its fifth annual BioSAXS Essentials workshop on October 30 to November 1, 2014.

This fall semester, Cornell High Energy Synchrotron Source (CHESS) furthered its educational goals through student-to-student outreach.

On the morning of Nov 20th, a group of 17 middle school students and 2 teachers from the Onondaga Nation participated in a series of activities facilitated by the Xraise staff from the Cornell Laboratory for Accelerator-based ScienceS and Education.

For most of CHESS’s history, it was not possible to use undulator insertion devices. The reason for this was that in order to counter-rotate electrons and positrons in the same storage ring there had to be a “pretzel” orbit that caused the two particle beams to avoid parasitic crossings (Fig. 1), but also not go through the centers of potential undulator sources.

Imagine building a chemical reactor small enough to study nanoparticles a billionth of a meter across.

RNA polymerase (RNAP) assembles an RNA strand corresponding to the DNA sequence of a gene, in a precisely choreographed series of molecular motions.
