- Tabletop layout
- Fast cycling time: ~ 3 hours to cool down, ~1.5 hours to warm up when completely empty
- Base temperature < 15 mK
- Magnet option: up to 1.8 T
Wiring:
- Microwave input: 12 SMP lines
- Microwave output: 4 SMA lines including HEMT amplifiers (4-12 GHz) and isolators (2-12 GHz)
- DC: 24 superconducting lines
