The European furnace insert in the MSL [Materials Science Laboratory] is developed to support research in the field of Bridgman crystal growth. The LGF [Low Gradient Furnace] consists of two heated cavities separated by an insulating, "adiabatic" zone. It is intended to provide restricted but well-controlled gradients between two stable temperature plateaux. Crystal growth is performed by translating the furnace over a stationary sample; thermomechanical stresses in the grown crystal are minimised by maintaining the solidified part of the sample in the heated cavity throughout processing. Alternatively, the insert can be used for thermodiffusion experiments by keeping the furnace stationary and using only the gradient capability. Isothermal experiments can also be carried out with suitable sample/cartridge configurations.  2, fiche 1, Anglais, - furnace%20insert

CHAMPS is a modular microgravity research furnace developed for the National Research Council' s Space Division. It was flown in a Get-Away-Special(GAS) container aboard the space shuttle STS-67 in June 1993 to investigate GaAs [gallium arsenide] crystal growth by liquid phase electroepitaxy(LPEE). Combining the advantages of both dedicated and generic experimental facilities, CHAMPS allows investigators to specify their own experimental configuration while at the same time providing them with generic peripherals. Configurable hardware included thermal and gradient furnace, levitator, etc., while generic peripherals included control and data acquisition, thermal insulation, and ground support equipment.  2, fiche 2, Anglais, - configurable%20hardware%20for%20multidisciplinary%20projects%20in%20space

The key element of the MOMO experiment assembly is a Bridgman furnace for low temperatures(< 100°C). The furnace generates a temperature gradient over a cylindrical glass ampoule containing the sample. The sample material for the first two flights was a succinonitrile(SCN) based compound, which has solidifying structures similar to those of a metal alloy. The furnace is accommodated on a linear drive, which can be moved over the sample ampoule for directional solidification. An endoscope from the liquid side of the sample provides optical observation of the solid-liquid interface. Recorded images are analysed after the experiment to determine parameters of the solidifying morphological structure.  3, fiche 3, Anglais, - ESA%20facility%20MOMO

Advanced Gradient Heating Facility(AGHF)... The AGHF supports the production of advanced semiconductor materials and alloys using the directional solidification process, which depends on establishing a hot side and a cold side in the sample(a temperature gradient). It provides an extremely stable temperature environment of up to 1, 400°C, high-temperature gradients of up to 100°C/cm in the solidification zone, slow movement of the gradient across a sample to provide slow growth rates, efficient cooling through the use of a liquid metal cooling ring attached to the sample container, and Peltier pulse marking capability. The AGHF consists of three modules mounted in one side of a Spacelab double rack : the Core Facility Module contains the processing chamber with the furnace inside; the Electronics Module contains the controls and equipment necessary to operate the furnace; and the Gas Storage Module contains argon for chamber repressurization and sample cooling.  2, fiche 5, Anglais, - advanced%20gradient%20heating%20facility
