Traditional directions of experimental work carried out and developed on the spectrometer are:

1. Study of liquid metals (Na, Ga, Pb, K, Li) and liquid-metal systems with impurities (melts K-O, Pb-K, Na-Pb, Li-H).

2. Studies of water ionic and hydrophobic solutions, including aqueous dispersions of carbon particles (fullerenes, schungite, soot).

3. Studies of quantum liquids in "bulk" state, and in confined geometry and films 4He of atomic thickness.

4. Studies of multicomponent crystalline and amorphous systems, including solid solutions, metallic oxides and hydrides, superionic conductors and triple impurity systems.

 5. Studies of reactor materials in a wide temperature range to improve security level of Nuclear Power Setups.

Time of flight diffraction mode on spectrometer DIN-2PI was, in particular, used to obtain structural information about the melts K, Na, Pb, Pb-K, Na-Pb, Li-N.
