Abstract
A compact high-pressure diamond-anvil cell equipped with an interchangeable force-generating device has been constructed and tested. Force can be applied to the anvils both mechanically using screws or a hydraulic press and pneumatically, by feeding compressed gas into a metal double diaphragm. The cell dimensions (a diameter of 44 mm and a height of 40 mm) allow placing it in a cryostat with an inner diameter of 48 mm, so that the optical axis of the diamond anvils is perpendicular to the cryostat axis. The parts of the diamond cell and the force-generating device are made of non-magnetic materials, which allows investigation in magnetic fields.
