- Description
- SLAC National Accelerator Laboratory is seeking sources for the proposed acquisition of a "dry" helium-3 backed, two-stage adiabatic demagnetization refrigerator (3He-ADR. Sources with products matching the listed requirements or with the capability to produce the subject unit shall register in the Interested Vendor Portal. This is not a Request for Proposal or a Solicitation and any submitted proposal shall be disqualified upon receipt. The cryostat should have four thermal stages: ES = experimental stage ("30 mK stage") HI#1 = heat-intercept stage #1 ("300 mK stage") HI#2 = heat-intercept stage #2 ("2.7 K stage") IS = intermediate stage ("60 K stage") Experimental stage (ES) basic requirements: 1. Base temperature T ≤ 30 mK 2. Temperature control with r.m.s. temperature variability ��T<10 μK (micro Kelvin) 3. Parasitic heat load P < 40 nW. 4. Hold time t > 45 hours under temperature control (T ~50 mK ; P~1 μW (microwatt)) 5. Cylindrical working volume with diameter 30-40 cm and height 20-25 cm. 6. Thermal and mechanical platform for attaching experimental packages 7. Platform made of gold-plated, oxygen-free high conductivity copper 8. ES instrumented with appropriate thermometry Heat-intercept stage one (HI#1) basic requirements: 1.Operating temperature range 280 mK -300 mK 2.Hold time t ≥ 120 hours at 300 mK; recharge time t ~ 4 hours (or better). 3. For non-regenerative methods, temp. control at 300 mK for P ~ 20 μW (microwatt). 4. Size sufficient to attach HEMT amplifiers and/or series-array-SQUID modules or similar devices; should have niobium shields and/or thermal clamping for superconducting coaxial transmission lines and/or thermal clamping of microwave components and terminations. 5. Includes thermal and mechanical structures for attaching components operated on the HI#1 stage and at the HI#1 temperature. 5. Stage made of gold-plated, oxygen-free high conductivity copper. 6. HI#1 instrumented with appropriate thermometry Heat-intercept stage one (HI#2) basic requirements: 1. HI#2 shall intercept heat just prior to the HI#1 stage. It is the major working location for active electronic components. 2. Shall provide a cylindrical thermal shield (can) enclosing both HI#1 and ES. 3. Must operate in continuous mode, providing operating temperature of the HI#2 without interruption or need for recharge, e.g. using a continuous and closed-cycle and dry refrigeration system. 4. Normal operating temperature range between ~2.7 K and ~3.0 K, with temperature stability to ��T<0.2 K (Kelvin) 6. System cooling power sufficient to handle P > 0.9 W at HI#2 at T = 4.2 K. 7. HI#2 shall have working space for attachment of HEMT amplifiers and/or series-array-SQUID modules with niobium shields and/or thermal clamping for superconducting coaxial transmission lines and/or thermal clamping of microwave components and terminations. 8. HI#2 shall have a thermal and mechanical platform for attachment of components operating on the HI#2 and at the HI#2 temperature. 9. Platform made of gold-plated, oxygen-free high conductivity copper. 10. HI#2 instrumented with appropriate thermometry. Intermediate stage (IS) 1. The IS shall provide a cylindrical thermal shield (can) enclosing the HI#2 ("2.7 K stage"), HI#1("300 mK stage"), and ES ("30 mK stage"). 2. The IS must operate in continuous mode, providing operating temperature of the IS without interruption or need for recharge. 3. The IS must maintain stable temperature in range of 60 K-70 K with temperature variability ��T< 1 K, assuming parasitic heat load P<20W. 4. The IS shall have working space for attachment and thermal clamping of cabling and ancillary components. 5. The IS shall be fully instrumented with suitable thermometers The cryogenic system should also include: 1. FAA paramagnetic salt pills ≥ 80cc in volume; superconducting magnets ≥ 4T 2. Thermal heat switches with easily accessible touch-sensors (and readouts); external motors for operating the heat switches should be computer controlled; Ferro fluidic feed-throughs and Kel-F isolators (for low thermal conductivity) should be used. 3. The cryostat and its operations (cooling, ramping, regenerating, warming, multi-stage temperature controlling, opening and closing of associated heat switches, opening and closing of associated valves, etc.) shall be automated. The control system shall include logging of temperatures and instrument status. Error checking and interlocks shall be used to prevent run away conditions, system failures, over voltage and over current conditions, mal-operation with large voltages or currents at unacceptable temperatures. PID temperature regulation shall achieve the specified temperatures and temperature stability noted above. The cryostat shal weigh no more than 350 pounds, no higher than 60 inches and the footprint shall be no larger than 24 x 24 inches.
