Physics Lab

The purpose of Physics Laboratory is to develop scientific temper, analytical capability among the engineering students and to understand the general scientific concepts required for technology and apply the concepts in solving engineering problems. This laboratory also explains scientifically the new developments in engineering and technology and to familiarize with the concepts, theories and models behind many technological applications.

The Physics Laboratory is employed to practice the scientific experiments – asking questions, performing procedures, collecting data, analysing data, and thinking of new questions to explore the knowledge in physics and materials science. Students can perform experiments on Uniform Bending, Torsion Pendulum, Spectrometer, Potentiometer, Lasers, Optical Fibre, and general electronic circuits. The laboratory also has provision to perform experiments on Post office box, Four Probe Method, Dielectric Constant Measurement, Photoconductivity measurement, Hall Effect, and Magnetic Susceptibility.

VASP Code

The Vienna Ab initio Simulation Package (VASP) is a computer program for atomic scale materials modelling, e.g. electronic structure calculations and quantum-mechanical molecular dynamics, from first principle.

Tubular Furnace (RT to 1400˚C)

A tube furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis. One possible design consists of a cylindrical cavity surrounded by heating coils that are embedded in a thermally insulating matrix. Temperature can be controlled via feedback from a thermocouple.

Box Furnace(RT to 1400˚C)

A box furnace is an electric heating device used to conduct syntheses and purifications of inorganic compounds and occasionally in organic synthesis. Here the high temperatures of around 1400 ˚C is reached due to the SiC heating rods present in the design. Temperature can be controlled via feedback from a thermocouple.

Constant Temperature Water Bath

A constant temperature water bath is a laboratory equipment made from a container filled with heated/constant temperature water. It is used to incubate samples in water at a constant temperature over a long period of time. There is a digital interface to allow users to set a desired temperature.

Microwave Bench X-Band

Microwave Test Bench are used for study of Microwave Characteristics like Guide Wavelength, Free Space Wavelength, Cut off Wavelength, Frequency, Klystron Characteristics, Gunn diode Characteristics, Klystron Mode Study, VSWR, Impedance, Reflection Characteristics, magic Tee, Directional Couplers, Dielectric Value, Power Measurement, Circuit parameters, Isolation Value, Insertion Loss, Attenuation, Gain, Directivity and radiation pattern of Antennas etc.,

Location
