ID10 consists fo two experimental stations: ID10-SURF / ID10-COH. Manageed by two teams, and the beamtime is shared in 50-50 mode

ID: U35 + revolver U35/U27 + U27, 1.5m each

optics:

  • high heatload H-deflecting double mirrors, vertical deflecting DCM with channel cut Si111 (or Si311 for high resolution)
  • 4:1 Be 2D lens, R300 -> 10um v x 35um h in SURF hutch, 1D lens to come
  • (optional) vertical deflecting mirror
  • 11:1 Be 2D lens -> 2um v beam

SURF hutch ~ 41m from ID

  • Double Xtal deflector (DCD), surface scattering (vertical stage unmounted)
  • 4.3m 2nd detector portal, horizontally rotatable

10^13ph/s at 200mA, 10um v x 35um h beam, standard 22keV

Experimental techniques: XRR/GIXRD/GISAXS/GIWAXS/XRF/XANES

special: XRR with DCD using 333+660 to reach qz = 7.5/A (https://doi.org/10.1107/S1600576724000657)

liquid surface XANES

  • using 4:1 lens, vertical deflecting mirror, no DCD, scan DCM but fix undulator gap (good for +/-100eV)
  • for different energies: set the 2/3 undulator set differently for different energy

sample environments / experiment:

  • Langmuir trough
  • liquid-liquid Langmuir trough
  • liquid-liquid chamber
  • LMCats chamber from Leiden for 2D material CVD on liquid metal
  • humidity chamber
  • high pressure CO2 chamber (120bar)

data (with Maciej Jankowski):

  • pipeline to XRR (ORSO format), GIXS / azimuthal integration
  • GIXS pipeline uses pyFAI fiberintegration
  • machine learning XRR (Schreiber’s group)

beamtime share:

  • 7 weeks / 6 months, 50% on liquid surface using DCD (mostly Langmuir trough and also LMCats)
  • 1.2 paper / proposal

Coherence application: liquid-surface XPCS (Amadei, Journal of Physical Chemistry B, 124 (2020))
