What is "sample environment"?

Let us think about "water". You will see water when you wash your hands, you go to river, it rains... In all cases, water is in the liquid state. But is water always in the liquid state? While you cook in the kitchen and boil water, you will see "steam", which is in the gas state. If you put water into a freezer, the water changes to be "ice", which is in the solid state.

In this way, materials can change their form according to the condition around the materials. While you perform an experiment to examine the physical properties, the objective material is called "sample" and the controlled condition around the sample is called "sample environment".

There are many types of sample environments such as:

low temperature

high temperature

pressure

tension

high magnetic field

humidity

Structure and dynamics of materials are precisely determined in the atomic level by the instruments at the MLF and it is very interesting to investigate how the structure and dynamics change according to the sample condition, especially at the extreme condition. Therefore, it is important to realize those sample environments at the MLF.
