Abstract
Many of the experimental techniques originally devised at room temperature now have been extended to low temperatures. There are two main reasons for taking the trouble to do this. Firstly, additional information regarding the temperature dependence of physical properties can be obtained. The new information can be compared with theoretical models which may, in some cases, be simplified in the absence of strong thermal disordering. Secondly, certain phenomena such as, for example, superfluidity in liquid 4He (see Chapter 3), occur only at low temperatures. Extending an experimental technique into the low-temperature regime introduces a whole new set of problems to overcome. In this chapter just a few of these problems and their practical solutions will be considered.
