DIL2
Oxford Instruments Kelvinox Dilution Insert DIL2
DIL2 was aquired in 2006, mainly financed by the
"SNF Förderungsprofessur Michel Kenzelmann".
It is equipped with a weak link, allowing access to the
range 1...2 K without removing the mixture.
Sample Mounting
Problems with DIL2
- The weak link was too weak, and there was no spacer on it.
We have shortened the weak section and put a spacer above
it.
- The gauges G1 and G2 do not work reliably. As a workaround,
the (earlier unused) G3 gauge has now a connection to the
beam dump.
