A short review of recent results obtained at the GOL-3-II facility is presented. This facility is an open trap with 12 m long plasma column with a longitudinal magnetic field of 4.5 T in the uniform part and 9 T in the end mirrors. There is the possibility to change the magnetic field configuration. Plasma density can be varied in 10¹⁴÷10¹⁷ cm⁻³ range. A microsecond electron beam with total energy of 0.2 MJ is injected into the plasma through the input mirror.

Collective interactions of an electron beam with a plasma and its fast heating are studied at this facility. An efficiency of collective electron beam deceleration up to 40% is achieved in a 10¹⁵ cm⁻³ plasma. The average electron temperature of ∼2 keV at plasma density (1–2) 10¹⁵ cm⁻³ is obtained. With two-stage heating of a dense (∼10¹⁶ cm⁻³) plasma the electron temperature of 300÷500 eV and the ion temperature of 100÷200 eV are reached.

Prospects of experiments on multimirror and «wall» plasma confinement at GOL-3-II facility are discussed.
