Abstract

This paper gives the way how the undergraduate students can actively participate in the main space
stream of the country by their engineering applications.The knowledge of basic mechanical engineering
and software knowledge can result in the participation in the projects provided by ISRO.

As a college project we started to work on the Far UV spectrograph designing and building. The
specifications are given by IIA(Indian Institute of Astrophysics).We used the basic strength of materials
and modal, buckling analysis for the designing of the spectrograph box.Then using softwares like
Autocad,PRO-E, and ANSYS we finished the designing and analysis.Aluminium (Al6061)is used as the material
for the box which is to be mounted on the satellite.The dimensions are maintained as the specifications
specifies.

Basic science goals are to get the details of Hot Gas in the Galactic Halo, Diffuse Continuum Emission,
Supernova Remnants,Clusters of Galaxies etc. The far UV region has not been studied in detail, so we
have chosen this range as our area of study.

As of optical design we are using a toroidal grating with an off axis parabolic mirror. the detector part
is going to be done in separate.The wavelength range is 900 to 1200 angstrom. The grating and other
optical components are fabricated in IIA. The tolerances are checked for all the components. OSLO is used as optical analysis software for the design.

Now we are doing the manufacturing part of the box and optomechanical designing of the spectrograph.
The facilities available in the workshop and machine shops of our college are enough for the
fabrication of the parts of the spectrograph box. We are planning to finish the building by April-May. So
I can add the manufacturing part and the working of the spectrograph in next few months.
Here we are trying to present how the colleges of under graduation can donate to the space community
through the help of the engineering knowledge of the students and with the help of basic physics laboratories
and the workshops of the college. IIA is collaborating with our college which gives a very
good chance to the students and faculty to get into the main space organization line. We students do this
as a project as well as to know the layers of the practical field of the engineering in the space science.
