Description
The Storage of ultra-cold spin-polarized hydrogen atoms offers the possibility of producing a high intensity nuclear polarized atomic hydrogen jet. We stored electron spin polarized atomic hydrogen at 0.4 K in an open 5 T magnetic storage cell. We observed directly the extraction of hydrogen atoms from the storage cell by flipping their spins using a 140 GHz microwave driven transition. Recent tests showed that the operation is greatly improved by using a 7.6 T magnetic field and 213 GHz microwave radiation. The results are being used to design a high intensity jet of nuclear polarized atomic hydrogen to be used as an internal target in the 400 GeV to 3 TeV UNK accelerator. (author)
