About this file

This document is an Addendum (No. 0001) to a solicitation for a Cryogen-Free Dilution Refrigerator System issued by Argonne National Laboratory under solicitation number 5-B175-Q-00521-00. The addendum specifically addresses a clarification request regarding system operation requirements, specifically confirming that when 18 liters (or less) of Helium-3 is used, the dilution refrigerator must provide specific cooling power measurements at different temperature points and achieve a base temperature at the designated measurement locations.

The solicitation, issued by the Department of Energy Office of Science, requires vendors to submit proposals by June 02, 2025, at 5:00 PM CST. Proposal submission must include completed forms (ANL-70, ANL-70A, ANL-71 COM Terms), specify pricing in USD using DDP or FOB Destination Incoterms, provide lead time, country of origin, and HTS code if applicable. Potential vendors are instructed to contact Jenna Doria at jdoria@anl.gov for any questions, with the deadline for inquiries set at May 23, 2025, at 12:00 PM CST.

05/23/2025 This addendum is being issued to modify the subject as follows:

To provide a response to the following questions.

1. Could you please clarify if the system operation requires 18 liters of Helium-3?

We require that when 18 liters (or less) of Helium-3 is used, the dil-fridge can provide cooling power of 14 µW @ 20 mK and 400 µW @ 100 mK measured directly from the sample mounting flange far away from the mixing chamber, and the base temperature can reach <10 mK with all factory installed wiring.

2. Will the Helium-3 be provided by the chosen offeror, or will Argonne utilize its own supply?

The He-3 will be purchased by Argonne from our own supplier.

3. Is it acceptable to propose a system that requires a larger volume of Helium-3?

No, it is not acceptable to propose a system that requires a larger volume of Helium-3.
