There is no science without instruments and tools. Today’s experimentalists are tremendously far away from the devices of the past. Now, it is sometimes almost impossible to identify some of them and guess their function.

We had to do our best to find out the function of historic scientific devices showcased in the hall of the main DLNP building. However, the application of some of them remained uncertain or even obscure.
If you are a JINR employee, visit the main building of the Dzhelepov Laboratory of Nuclear Problems and have a look at what was used to do science 60, 50, 40 years ago.
