Commissioning

The Near Experimental Hall is currently under construction, to create additional

space for hutches and support labs. Recent storms may delay the start of Run 15

5

The Near Experimental Hall will be optimized for LCLS-II in the

12-month shutdown (2 new hutches, and upgrade of 3 existing)

• 9 instruments available in total for LCLS-II

• Phased delivery over 2020 – 2023, dependent on resources

LCLS-II-HE (“High Energy”) received Critical Decision-0

(DOE’s approval of Mission Need) in December 2016

This extends the peak

energy from 5 keV to 12 – 20

XRD CSPADs

Modular Drive beam and diagnostic system

Schedule : 4 user experiments in 11 days

Diagnostics designed for quick change between

XRD and XRTS set ups

XRD XRTS

• The first two standard configurations XRD and XRD+ TS delivered in May 2016

Analysis and Computing Update

Easier/faster analysis: write code that looks like it runs on 1 CPU, but run (in

real-time) on as many CPUs as you want, producing small HDF5 files:

• https://confluence.slac.stanford.edu/display/PSDM/MPI+Parallelization

• “FFB” real-time analysis faster because spinning disks have been replaced

with flash

• Jupyterhub now supported for “in browser” python analysis: • https://confluence.slac.stanford.edu/display/PSDM/JupyterHub

• Psana is now a package in the world-standard “conda” Python environment: • https://confluence.slac.stanford.edu/display/PSDMInternal/Conda+Release+System

Analysis update: Support for Crystallography/SPI

Uses graphical tool “psocake”:

Interactively tune peak finding and indexing parameters

Interactively optimize detector position in 3D space

Easy masking of bad pixels / ROI

Quickly jump to interesting events by clicking on a 1D small data plot

Launch peak finding/indexing on arbitrary number of cores using MPI
