Until recently it was assumed that in the recombination process of two polarized atoms into a molecule, any initital nuclear polarization carried by the atoms is lost. An experiment recently carried out at the NIKHEF polarized internal target facility by van den Brand et al. [1] has called this assumption into question. The PINTEX collaboration is planning to measure the nuclear polarization of molecular hydrogen and deuterium formed by recombination inside a storage cell in the presence of a strong magnetic field. The measurements will be carried out at the Indiana Cool er making use of the PINTEX detector. The experimental technique including a new single loop superconducting solenoid will be described in detail together with the experimental program.
