Mounting Samples
1” and 2” mounts are available. CuBe clips or double-sided tape can be used to
adhere samples to the mounts. Use the smallest piece of tape possible to avoid
excessive outgassing. Silver or Carbon paint (allowed to dry) is also an option
for mounting. Molybdenum masks can be secured to avoid using tape or paint.
For angle-resolved experiments, must use 1” holder.
