TEMPUS MSL-1 Experimentatorenunterstuetzung Schlussbericht

Abstract

The sample holders for the MSL-1 mission of TEMPUS were developed, manufactured and tested in the framework of this Experiment Support Project. Three sample holder types for the different experiment classed were developed: sample holders with a horizontal slit for the radial observation of strongly evaporating samples, sample holders with crossed slits for the observation of the nucleation front motion and cage sample holders for weakly evaporating samples for which a good radial observation was of special importance. In a prototype test program sample holders were build from different materials. Tests were performed with these prototypes, e.g. thermal shock tests with liquid sample materials at temperatures of up to 2000 C, vibration tests and tests of the coupling of the sample holders to the RF fields of the leviation coils. As a result, silicon nitride was selected as the material for the flight sample holders. After the Design Review sample holders were custom made for each of the flight experiments. In addition, a Ti-sample was integrated into a sample holder which was used as a sublimation pump during the mission. The sample holders were cleaned and shipped for sample integration to the Kennedy Space Center in special transport containers in an ultrapure noble gas atmosphere. In addition, parameter sets were developed for the new subsystems Residual Gas Analyzer and Active Sample Oscillation Damping. The parameter set development at DLR as well as the operation of the TEMPUS Development Model at DLR was supported by Dornier.
