The Department of Energy, through the Lawrence Berkeley National Laboratory (LBNL), is conducting a Request for Information (RFI No. AA-2024-08) to identify potential sources capable of providing advanced flexure systems and vacuum tank sets for the Advanced Light Source Upgrade (ALS-U). This upgrade is critical for enhancing the beam brightness and coherence of the existing soft X-ray facility, necessitating two-degree-of-freedom mirror positioning systems that ensure precision and stability of the X-ray beam. Vendors responding to this RFI must demonstrate expertise in fabrication, machining, and precision metrology, with submissions due by October 8, 2024. Interested parties should contact Arielle Anoop at aanoop@lbl.gov or Martha Grausz at mggrausz@lbl.gov for further information.
