## Description

The Advanced Photon Source Upgrade Project (APS-U) is planning a storage-ring upgrade that will reduce the electron-beam emittance by a factor of ~75. This ultra-low emittance is achieved by replacing the present storage ring lattice with a multi-bend achromat (MBA) lattice. The MBA lattice will increase the x-ray coherent fraction by two orders of magnitude and decrease the horizontal source size by a factor of ~20.

In addition, the APS-U is planning to build eight new featured beamlines and make optics upgrades to many others. One of the feature beamlines built as part of the APS-U with be dedicated to Coherent High Energy X-ray (CHEX) studies at sector 28ID of the APS. The CHEX beamline will operate with a combination of integrated and shared instruments. Three shared instruments will be installed on each branch line for use with multiple systems.

The maximize the systems and scattering geometries that these shared instruments can accommodate requires a large Eulerian cradle that can be used with any of them. The large cradle would be swapped with the hexapod present in the typical diffractometer configuration. We will be conducting a Pre-Award meeting on Tuesday, March 5th at 9:00 am CST. If you'd like to attend, please let me know and I'l send you a link to join the meeting.
