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.
DIL2 Sample mounting
used in | MA15 | MA11 | MA02 | MA09 |
sample space diameter [mm] | 17.3 | 17.3 | 23.6 | 45 |
max. sample diameter [mm] | 16 | 16 | 18 | 35 |
distance from M6 thread to beam center [mm] adjustable by about +- 10 mm | 51 | 51 | 97 | 194 |
allowed size below beam center [mm] | 35 | 35 | 60 | 24 |
On the mixing chamber as well as at the end of the
sample holder there is an M6 hole.
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.
- The sensor on the mixing chamber is defect. A new one is ordered.
In the meantime, an additional sensor on the copper holder is
installed.
- The gauges G1 and G2 do not work reliably.
