A laser source of polarized protons and H − ions

The polarization of protons by the pickup of polarized electrons from optically pumped sodium atoms in a strong magnetic field has been studied experimentally. A proton polarization of (65±3)% has been achieved for a charge exchange in a field of 15 kG. The results of the development of the source o...

Summary:The polarization of protons by the pickup of polarized electrons from optically pumped sodium atoms in a strong magnetic field has been studied experimentally. A proton polarization of (65±3)% has been achieved for a charge exchange in a field of 15 kG. The results of the development of the source of polarized protons and H − ions for accelerators which is based on a new polarization method are discussed. A pulsed intensity of polarized protons of about 1 mA and a H − current of about 0.06 mA have been obtained by charge exchange in a xenon gas cell.
