    • Note that for a particle diffusing in one dimension with an exponentially distributed path length between scattering events, the diffusion coefficient is given by D = v¯λ, where λ is themean free path. For hopping in one dimension from pore to pore with a fixed path length A, D = 1/2 v¯A,.

    • It is not strictly accurate to refer to thermal Ps in the sample we discuss here; the small pore size means that Ps cannot cool to an energy that is lower than the Ps confinement energy in the pores (see Refs. [16-18]). However, once Ps has reached this minimum energy it will have a constant diffusion coefficient and so may be considered to be "thermal" for the present purposes

    • One of the disadvantages of using a high-voltage buncher is that there is a minimum beam energy one can use. In this case it was ~1 keV
