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.

Problems with DIL2

The weak link is too weak. For the first experiments we will use a simple copper sample holder, and use the sensor on the mixing chamber.

DIL2 Sample mounting

used in	MA15	MA11	MA02	MA09
sample space diameter [mm]	17.3	17.3	23.6	45
max. sample diameter [mm]	12	12	18	35
distance from thread to beam center [mm] adjustable by about +- 10 mm	40	51	97	194
allowed size below beam center [mm]	64	30	60	24

On the mixing chamber, there is a bolt with an M5 thread (on the sample container a 7 mm deep hole with an M5 thread is needed).

Sensor Calibration

The calibration curve in the FemtoPower system from Oxford Instruments is generic. For more precise values use the table below.
