The experiment will investigate the nuclear polarization of hydrogen and deuterium molecules recombined from nuclear polarized atoms under different conditions (surface material, temperature, external magnetic field, and spin states of atoms). The experimental setup consists of three components^*:
1.) An atomic beam source [1] to deliver a beam of nuclear polarized hydrogen and deuterium atoms.
2.) A Lamb-shift polarimeter [2] to analyse the polarization of the stored particles.
3.) A recombiner including a superconducting solenoid with the ionization and electrostatic extraction system.
The present status and first results will be presented.
