An undulator source beamline for soft X-ray imaging

A water-cooled mirror system for synchrotron radiation

“…The first mirror has been installed and operated at the National Synchrotron Light Source (NSLS) on the X-17T mini-undulator beam line and will be moved to the permanent X-1 beam line when a new, more powerful undulator is installed there. [4,5] The X-1 beam line will be used primarily for soft x-ray imaging using such methods as microscopy and holography, in the wavelength range of 1 to 5 nm. The total incident power on the mirror may be as high as 720 W with a peak power density of about 70 W/cm2.…”

Predictions On The Performance Of The Soft X-Ray Undulator

“…The photon intensity for the mtn harmonic X m of an undulator with N periods of length X o each and magnetic field strength parameter K = 0.93 Bmax (T)X o (cm) is 1 where a is the fine structure constant 1/137, 0 is the angle off of the undulator axis, and 4) is the azimuthal angle.…”

“…Am of an undulator with N periods of length each and magnetic field strength parameter K = 0.93 Bmax(T)ao(cm) is I (6,4) = aN2y2 e L Gm(K,6,¢)Hm(K,6,a) (photons/s, 100% BW, A, steradian) (1) …”
