New plans for next-step experiments on a multiple-mirror confinement in GOL-3 are discussed. The proposed changes in the hardware configuration include separation of the existing GOL-3 device into two independent plasma facilities. The first device will continue research on physics of highly turbulent electron-beam-heated plasma. It will use the existing generator of the electron beam and a shortened part of the existing solenoid. The second device will be devoted to a new experimental program on studies of efficiency of multiple-mirror end sections that should decrease power and particle losses from the trap. Details of the physics and upgrade plans for the new device, tentatively named GOL-NB, are discussed.
