APS-U and MPE Beamlines

Here we provide periodic status updates on beamlines which will be operated by the Materials Physics and Engineering group after completion of the APS Upgrade.

The Advanced Photon Source is currently undergoing a comprehensive upgrade to replace its original electron storage ring with a new, state-of-the-art accelerator.  This upgrade will increase the brightness and coherence of the x-ray beams by orders of magnitude.

You can read more about the APS upgrade at https://www.aps.anl.gov/APS-Upgrade.

The group is developing new data analysis, storage and visualization pipelines in collaboration with other APS groups.

Return to User Operations

Based on current information from the APS Upgrade project, we anticipate the following schedule for beamlines supported by the MPE group.  Note the storage ring current will increase from 25mA to 200mA over the course of the first year as the accelerator gets commissioned.  

  • Spring-Summer 2024: Startup of APS-U storage ring and commissioning of beamline optics, controls, and instrumentation at all beamlines.  A limited set of general-user experiments may be possible at 1-ID and 6-BM.
  • Fall 2024-Winter 2024:  Gradual return to user operations with an increasing complement of techniques available at 1-ID and 6-BM.  Continued technical and scientific commissioning of 20-ID (HEXM).  This will include First Experiments proposals.
  • Spring 2025-Winter 2025:  Return to full user operations in 1-ID and 6-BM, with ramp up of user operations including general-user experiments at 20-ID .
 
Beamline 1-ID
  • The initial undulator will be a permanent magnet device; this will be upgraded to a superconducting undulator (nominally identical to 20-ID) ~year after APS-U startup.
  • The initial monochromator will be the vertical offset system operational at 1-ID over the past ~20 years; a new one (from Cinel, nominally identical to 20-ID) will be installed ~year after APS-U startup. 
  • The 1-ID-C instrument has been updated through installation of a ~4.5 m long optical table, new sample-manipulation-system and detector-motion-system.  This endstation will be optimized for diffracted beam aperture measurements.
  • The 1-ID-E instrument will remain similar to it's status prior to APS-U and be used for multi-modal measurements.
 
Beamline 6-BM 
  • The SEES program will operate 6-BM-B (taking over for compress); MPE will continue to operate 6-BM-A with similar infrastructure, to allow both energy-dispersive diffraction and imaging.  Additional phase contrast is expected for imaging, which may provide increased sensitivity.
 
Beamline 20-ID (HEXM)
  • This is a new feature beamline with one optical station 20-ID-A and two end-stations: 20-ID-D and 20-ID-E.  Existing 20-ID-B,C (mono) end-stations will remain but not be used for operations.
  • All design work is complete.
  • High-throughput HEDM instrument moved from 6-ID-D to 20-ID-D in December 2023.
  • New monochromator (from Cinel, horizontal offset), installed at 20-ID-A in January 2024.
  • Ongoing installation of infrastructure (fire suppression, HVAC, etc) and assembly of several components at 20-ID-E, including overhead rail, sample manipulation systems and detector motion systems.
