Instrument Development Service Centre (IDSC)

This is an ongoing project of the division at the department of Physics, Cotton College Guwahati. Under the scheme new instrument /experimental set up are developed as well as instrument/experimental set up of the colleges which become defective are repaired. Repairing of instruments of college laboratories are carried out on 'first come first service' basis. Development of instrument/experimental set up are also taken up on a central need of the colleges.

Some of the institutions which have received services from the centre are Cotton College, Guwahati; North Guwahati College, North Guwahati; M. C. College, Barpeta; B. Barooah College, Guwahati; Handique Girls' College, Guwahati; Jorhat Science College, Jorhat; Birjhora Science College, Bongaigoan; Darrang College, Tezpur; Pandu College, Guwahati; Pub-Kamrup College, Baihata Chariali; B.H. College, Srimanta Sankar Academy, Guwahati; Solid State Laboratory, Gauhati University; IIT, Guwahati and College of Veterinary Science, Khanapara, Guwahati.

Instrument designed and developed by IDSC

Transistor characteristic experiments (N-P-N/P-N-P); L-C-R experiment; Anderson bridge experiment; 'R-C couple amplifier; Multi vibrator experiment ; Ripple factor experiment for full and half wave rectifier; Low cost demonstrative experiment using LASER ; Resonance column experiment ; Photo - Cell experiment; AND, NOT, NOR gate kit ; Junction diode kit for forward and reversed biased analysis ; Thermistor kits etc.; Simplified GM counting system for studying nuclear disintegration ; Resistivity measurement of thin metal at different temperature; Study the property of liquid using laser and ripple tank ; Modification of Melde's experiment with electronic switch and frequency generator.

New instrument designed and developed

  • Micro to mill volt converter
  • OPAM checker
  • Temperature controller relay drive
  • IC regulated power supply etc

New experimental kits developed by IDSC

  • Verification of De-Morgan's theorem
  • Verification of Norton's and Thevenin's theory
  • Study of OPAMP by measuring input offset voltage, input offset current and input bias current.
  • Study of open loop gain of an OPAMP
  • Study of gain of an OPAMP in inverting and non-inverting condition (closed loop gain )
  • Measurement of Stefan constant using thermocouple and micro to milli volt converter.
  • Determination of the value of self-induction using L-R circuit

Repairing of Instrument

UPS, C.R.O, Voltage stabilizer, VTVM, Signal Generator, Microscope etc., of a number of institutions and research laboratories.
