Abstract

A double-polarized dd-fusion experiment is under preparation at PNPI, Gatchina. The experimental program includes themeasurements of the asymmetry in the differential cross section of the reactions d_pol + d_pol → 3He + n and d_pol + d_pol → t + p. The spin-correlation coefficients Cz,z and Czz,zz will be measured to determine the quintet-state suppression factors for both reactions, for which quite different theoretical predictions were made and which are very important for the design of future neutron-lean fusion reactors. The total cross sectionmodification for polarized d–d fusion will also be investigated. An increase by a factor of 1.5 was already deduced for the d + 3He and the d + t reactions. The experimental setup and the future upgrade plans are described.
