High Temperatures

The heater of the high temperature furnace (HTF) consist of a resistive Nb double cylinder element. Radiation shields made of Nb reduce the thermal loss. Maximum reachable temperature is 1900 °C. For temperatures up to 300 °C the furnace can be filled with Ar or He exchange gas to improve regulation stability. Further a special version of the furnace with a reduced diameter for usage inside the CCM-7.5T vertical magnet is available.
Compact dimensions are the key feature of the infrared light furnace (IRF). The sample is placed at the focus of four halide lamps, therefore restricting the sample volume to a few mm³. The sample can be heated in vacuum or any convenient atmosphere up to ambient pressure respectively. Of course the maximum temperature depends on pressure.
For experiments using a polarized neutron beam a polarized neutron furnace (PF) with special bifilar heater cartridges is availble for the temperature range up to 700 °C.
The circulation thermostat furnace (CTF1) for the temperature range -20 °C to 200 °C uses a thermalized cirulating medium allowing for a precise regulation of the particularly homogenous sample temperature.
For research, e.g. on rechargeable energy storage systems such as lithium-ion batteries, dedicated heater elements (battery furnaces, BF) are available. Depending on battery size and temperature specification the furnaces have to be designed and manufactured.
