Sample Mounting Platform
The sample mounting platform is used to mount a sample on an oven heater stick and to
properly position the copper shields around the sample mounting area. Section 3.3 and
Figure 5-6 provide more information about mounting samples.
○
Copper-Foil Shields
The shields are slips of high-purity copper foil. You will wrap a shield around the sample
and sample mounting area of a heater stick to provide thermal homogeneity over the sample.
Refer to Section 5.3.2 for more information about how the shields are used.
○
Tweezers
A pair of Delrin plastic tweezers is included for your use in the sample mounting process.
○
Alumina Cement
The water-based alumina cement provides good thermal contact between the sample and
heater stick. It also holds the sample firmly in place during vibration.
○
Heater Sticks
These heater sticks are used as the heater, thermometer system, and sample holder of the
VSM Oven option. The heater stick plugs into the bottom of the oven sample rod. Sections
5.2.1 and 5.4.1 and Figures 5-1 and 5-7 provide more information about the heater sticks.
○
Mounted Nickel (Ni) Standard
The "mounted nickel standard" is an oven heater stick mounted with a small chip of pure
nickel. You can verify the temperature calibration of your VSM Oven option by measuring
the Curie temperature (T
c
= 627 K) of the nickel chip.
5.3.1 Sample Mounting Platform
Figure 5-6. VSM Oven sample mounting platform
Shown in Figure 5-6 is the oven sample mounting platform. This platform was designed
specifically for use with VSM Oven heater sticks. The heater sticks are mounted in the center
groove down the long axis of the platform, with the bottom of the stick aligned at the marker
labeled “0”. Section 3.3 has more information about mounting a sample.
The heater stick locks are used to hold the heater stick firmly in place so that it does not slip out
of position while you mount a sample. After you have positioned the heater stick properly, rotate
