Weak Link or not?

Weak Link

• Temperatures 0.1 K ... ~ 4 K accessible, with stable temperature control while the mixture is in.
• Base T slightly increased (~ 10 mK). May be more, when the sample is heated by neutrons, a changing magnetic field or vibrations.
• Temperature changes are quicker

Strong Link

• Base T slightly improved, especially when heat sources are present (neutrons, eddy currents).
• Stable Temperature between 0.8 K .. 2 K is not possible.
• Temperature changes between T < 0.8 K and T > 2 K need time consuming interventions (removing / condensing mixture).
• Base T slightly improved, but the T accuracy might be less than with the weak link.
