Hydrogen cold neutron source calculations for different ortho/para mixtures
Journal Article

· Nuclear Instruments and Methods
The results of Monte Carlo calculations of a cylindrical hydrogen cold neutron source in a tangential beam tube are discussed. The dependence of the cold neutron output on the relative ortho/para abundance was studied at the hydrogen boiling temperature 20.4 K. With a suitable choice of moderator cylinder length the output was found to be independent of the ortho/para mixture. Finally, the maximum output was obtained with a mixture rich in parahydrogen.
