  text: Studies of 2-D atomic hydrogen at high densities on helium surfaces have been
    plagued by the heating of the surfaces due to recombination, which dissipates
    more than 52, 000K for each recombining pair of atoms in the cell. When hydrogen
    recombines on a surface, it deposits less than 4% of its energy at the point of
    recombination and the rest is carried off by the excited molecule. We have designed
    a maze to absorb most of this energy, and carried out a Monte Carlo simulation
    to show that approximately 87% of the energy is dissipated in the maze, preventing
    the surface from getting excessively heated, even at high surface densities. This
    simulation varies the number of inelastic collisions with the maze wall for complete
    relaxation, the fraction of elastic collisions, and the angular distribution of
    excited molecules desorbing from the walls.
