In order to reach this goal a unique thermostat named TS-3000K for neutron scattering experiments was designed. It allows the heating of volumic (as cylinder of =81 mm, h=104 mm, t=1mm) metal samples (like W, Ta, Nb) until 2496 K. We have difficulties connected with the unavoidable background done by neutrons scattered on thermal shields and heather as seen in measured scattering neutron spectra.

It is possible to levitate a block of polycrystalline sample (or even single crystal) by some technique? I know that some group do such high temperature measurements on levitated molten liquid droplet. The heating can perhaps be done by lasers. One will have then less background and measurements can be done in a neutron spectrometer like IN4/IN6 at the ILL for example?
Take a look at this. Apparently the same group have already used their levitation furnace for neutron scattering experiments.
