Questions & Answers NIST Solicitation No. AMD-TC-RQ-22-00906 Brand-Name Only Closed-cycle mechanical cryocooler to Sumitomo
1. The solicitation states that “The Cryocooler shall be a Sumitomo RDK-101D cold head, with cooling power greater than 100mW at 4K.”
Question: Does the end user require the CNA-11C compressor? What is the specific cooling power requirement?
Answer: Yes, the Government requires the CNA-11C compressor. The cooling power specification is revised to: “The Cryocooler shall be a Sumitomo RDK-101D cold head, with cooling power greater than, or equal to, than 100mW at 4.2K.”
2. The solicitation states that “The coldest stage of the cryocooler must reach temperatures below 3K with no heatload.”
Question: Can you confirm that the Part Number RDK-101D associated with this specification is correct?
Answer: The full part number should be: RDK-101D-DL, as this gets us below 3K.
The RDK-101D-NR (as stated) is not guaranteed to go below 3K. The Specification table included in the Requirements document is revised to include this change in Part Number as follows:
| Part Number | Quantity | Description |
| 10/RDK-101DL-NR | 1 | RDK-101DL 4K Cold Head (non-RoHS) |
| 10/CNA-11C(GM) | 1 | CNA-11C Air-Cooled Compressor |
| 10/RV21ZN0445BQ | 1 | CNA-11C Power Cable 5M |
| 10/RW10ZN1011BQ | 1 | Flexline, Sup 10Ax3M |
| 10/RW10ZN1012BQ | 1 | Flexline, Ret 10Ax3M |
| 10/RV21ZN0221EQ | 1 | CH Cable, 6M (4KGM series) |
| 10/TOOL KIT A11 | 1 | TOOL KIT (101D-A11) |
3. All other Terms and Provisions remain unchanged.
