Abstract

We have recently carried out a neutron powder diffraction experiment at high pressure using nano-polycrystalline diamond as opposed anvils. Although spurious diffraction peaks from these anvils are rather large, a few peaks from Pb sample with 0.7 mm³ volume were clearly observed. Future potential and problem of the current scheme toward neutron diffraction at the highest pressure regime have been demonstrated.
