Academic Activities

Since installation of TAS a number of researchers from the neutron scattering group and different Universities have been carried out their research work in the neutron scattering laboratory for their academic degrees. Among them three scientists have been awarded Ph.D. degree, three have obtained their M. Phill degree and about 20 students have completed their research work to obtain their M.Sc. degree. Moreover, a number of students are presently using this research facility for M. Sc., M. Phill. and Ph. D. degree.

NAA Group is very keen to collaborate with almost every University of the country. About sixty students from different universities and other scientific organizations of the country were carried out their research works at NAA laboratory to obtain academic degrees, like M. Sc., M. Phil. and Ph. D with the guidance of laboratory experts.

A number of academic degrees have been achieved working in the neutron radiography laboratory. One Ph. D., 2 M. Phil. and 15 M. Sc. students from different universities so far have completed their thesis from this laboratory. A number of students are presently working for M. Sc., M. Phil. and Ph. D. degree.
