Clamp cell with $in$ $situ$ pressure monitoring for low-temperature neutron scattering measurements

Abstract

A clamp pressure cell for neutron scattering experiments at low temperatures and in external magnetic fields under pressure up to 2~GPa has been fabricated and tested. The cell provides optical access to the sample space that allows instantaneous pressure determination during sample loading, cooling and measuring using ruby and/or samarium doped strontium tetraborate fluorescence monitoring. A new calibration curve of the pressure-induced shift of the ${}^7{D}_0{-}^5{F}_0$ (0-0) line in the fluorescent spectrum of SrB${}_4$O${}_7$:Sm${}^{2+}$ for moderate pressures, $P⩽2$ GPa, is given.
