Beamline M1 Mirrors

Amendment 1 is hereby issued to this RFQ on September 4, 2025 to extend the Proposal Due Date until September 25, 2025. All other terms of this RFQ remain the same. Please ensure that you have reviewed all attachments.

Lawrence Berkeley National Laboratory (“University” or “LBNL”) requests a proposal for Beamline M1 Mirrors. ALS-U is an upgrade project to the LBNL Advanced Light Source. The ALS is a 1.9 GeV storage ring operating at 500 mA of beam current. It is optimized to produce intense beams of soft x-rays, which offer spectroscopic contrast, nanometer-scale resolution, and broad temporal sensitivity.

The ALS facility includes an accelerator complex and photon delivery system that is capable of providing the foundations for an upgrade that will achieve world-leading soft x-ray coherent flux.

The existing ALS provides a ready-made foundation, including conventional facilities and also includes extensive beamlines (up to 40 simultaneously operating beamlines) and instrumentation, an experimental hall, computing resources, ancillary laboratories, offices, and related infrastructure that will be heavily utilized in an upgrade scenario.

The ALS will be upgraded with an MBA lattice design that will provide a soft x-ray source that is orders of magnitudes brighter — an up to 100-1000 times increase in brightness — and will provide a significantly higher fraction of coherent light in the soft x-ray region than is currently available at ALS.
