| Flux |
0.6x10E(10), X-Ray photons per second through a 200 um aperture, 300 mA, 2.6 G
eV, 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.
