MMR Technologies Hall effect

MMR Technologies Hall effect Variable Temperature Hall Dewar The VTHS Dewar is a low-profile Dewar designed to fit between the poles of a magnet to enable measurements to be made of the resistivity, Hall mobility and other properties of materials over a wide range of temperatures. Guarded triax leads provide electrical input to the sample via similarly guarded leads on a Kapton Harness to the sample on the cold stage. A Hall sensor immediately adjacent to the sample allows measurement of the magnetic field at the sample location. - Operating Temperature: 70 K to 730 K - Temperature Stability: ± 0.1 K with MMR's Programmable Controller - Temperature Response: 1 K/sec - Cooling Capacity: 250 mW at 85 K with nitrogen; 500 mW with Ar at 90 K - Cold Pad Size: 14 mm x 10 mm - Standard Window Material: Fused silica - Optional Window Materials: Sapphire, Quartz. - Guarded triax leads to sample - Four sample leads for Van der Pauw measurements - Extra BNC lead for heater for Seebeck measurements - Simple sample mounting - Integral Hall sensor at sample site - Compatible with two different MMR electromagnets, allowing maximum flexibility in sample analysis - Dewar Dimensions: 6.0" L x 2.5" W x 0.75" H at sample - Weight of Vacuum Chamber: 170 g (6 oz)
