title: Large volume Bridgman seal cell for neutron scattering experiments at ultralow temperatures.
abstract: A pressure cell (maximum working pressure of 100 bars) has been developed for neutron scattering experiments at ultralow temperatures (T<100 mK) which makes use of a Bridgman seal design more usually seen in higher temperature experiments in the kilobar range. The large volume of the cell ( approximately 18 cm3) and its construction from a high-strength aluminum alloy make it suitable for inelastic neutron scattering experiments. The cell has been proof tested in operando in search for the supersolid state of helium-4.
