Conceptual design proposed for the M2-f/5-Nasmyth support system of the Telescopio San Pedro Mártir project

Abstract

The work that is presented is in its early stage. The intention of this document is to present the conceptual proposal of the design of the cell for Nasmyth-f/5 secondary mirror (TSPM-M2-f/5-Nasmyth), its support system and the mirror of this configuration for the "Telescopio San Pedro Mártir" (TSPM) project. In order to obtain more precise input data for the requirements of the telescope in terms of its: weight, center of gravity, interfaces with the telescope spider assembly and manufacturing viability. The goal of providing accurate data for the mechanical studies of the telescope was fulfilled. With this we ensure more realistic results in the opto-mechanics performance analysis of the whole telescopés. The telescopés requirements are the input data for the Opto - mechanics performance and survival analyses, both studies done by CIDESI. For this, it is necessary to have for this telescope configuration a conceptual proposal design of TSPMM2- f/5-Nasmyth. We present the TSPM-f/5 Nasmyth support system proposal, which include the M2 cell, mirror and interface. Finite Elements Analyses (FEA) results of the support system and the mirror are presented too. In the conclusion we present some evidence of the pending future work for this study.
