A removable temperature sensors holder for cryogenic Rayleigh-Bénard convection cell
Original language description
A removable holder carrying a set of miniature temperature sensors inside our Rayleigh-Benard convection cylindrical cell has been developed. The sensors should not disturb the temperature and velocity fields of the buoyancy-driven turbulent flow of our working fluid cryogenic helium gas (similar to 5 K). The cell, 300 mm both in diameter and height, must withstand the overpressure up to 2.5 bar, which is why all its parts are welded together. The holder consists of a pair of identical feedthroughs (each with 6 glass-sealed pins), constantan wires (0.1 mm), Be bronze springs and insulating elements and enables installing up to 6 sensors simultaneously, with the option to replace the damaged ones. We already used two such holders and obtained a map of local temperature and its fluctuations in 12 positions inside the cell.
