| Spot Size |
0.3H x 0.5V mm, adjustable. |
| Optics |
double-crystal monochromator Si(111), beam focused by a toroidal mirror. |
| Flux |
0.5 x 10E(10), X-Ray photons per second through a 200 um aperture, 300, 2.6 GeV, lambda 1 Ang
|
| Flux Details |
flux measured in 1997 corresponds to NSLS x-ray ring emittance of 90 nm-rad.
NSLS x-ray ring emittance has improved to 45 nm-rad, and this has resulted in
about a factor of 2 increase in the delivered fluxes. A more up-to-date
sampling of the flux is not yet available.
