About this file

This is an Addendum and Acknowledgement Document (Addendum No. 02) issued by Argonne National Laboratory's Procurement Department on February 10, 2026, for RFP 6-S176-Q-00096-00 regarding the 12-ID High Heat Load Mirror System. The addendum addresses a clarification request regarding conflicting specifications in the Statement of Work concerning yaw (qx) rotation functionality. Section 2.5 of the SOW specifies that yaw rotation must be motorized, while sections 2.2 and Table 3.2.1 request manual yaw motion adjustment. Argonne's response clarifies that yaw can be changed through motorized vertical kinematics, but a dedicated motorized stage is not required for yaw adjustment as long as an alignment method is available.

Offerors are required to acknowledge receipt of this addendum by signing and returning a copy of the letter via email to the Procurement Department. This document modifies the existing RFP requirements and must be incorporated into proposals. The solicitation remains a firm fixed price proposal opportunity evaluated on best value criteria, with all proposals subject to the technical specifications and requirements outlined in the original RFP and subsequent addendums.

02/10/2026 This addendum is being issued to modify the subject REQUEST FOR 6-S176-Q-00096-00 as follows:

1.Add response to a request for clarification: In reference to this tender opportunity for the 12ID Mirror System, the qx (yaw) rotation is stated as needing to be motorized in section 2.5 of the Statement of Work (Enclosure 3). However, in section 2.2 and Table 3.2.1 of the same document it asks for the yaw motion to be manually set. Can you please let us know which version is correct (or can we choose?)

RESPONSE: Yaw can be changed due to motorized vertical kinematics, but we do not need particular motorized stage just for Yaw as long as we have a way of alignment.
