Layout of new experiments on the observation of spontaneous electron–positron pair creation in supercritical Coulomb fields

Collisions of bare heavy nuclei implemented by means of merging-beam technique are suggested for the study of remarkable phenomena appearing in very strong fields created when distance between the nuclear surfaces approaches zero. Suggested here is to build a collider with two beams of actinide nuclei merging within a common straight section. Principal parameters of this collider are outlined. (author)
