Abstract

The Max-Planck-Institute for Extraterrestrial Physics (MPE) is involved in the investigation and optimization of the indirect slumping technique for the manufacturing of thin glass mirror segments to be assembled in lightweight X-ray telescopes. During the last year, we started to analyze the influence of vacuum environment on the results of this thermal forming process. The realization of slumping in vacuum offers theoretically several advantages, like the absence of air between the glass and the mold and a cleaner process chamber. Furthermore, the heat exchange is different with respect to a standard air-oven and this might have positive effects during the important heating and cooling phases of the process. All these aspects will be considered in the paper and the current status in the development of the MPE vacuum-slumping approach will be outlined.
