Pulsed Positron beam based Lifetime Spectroscopy
Our Pulsed positron beam is based on 22Na radioactive source & W moderated DC beam. Chopper with a pre-buncher and a main buncher operating in tandum produce the beam pulsing .
Variable low energy positron beam
Low energy positron beam setup with beam energy range of 0.1 – 20 keV is used in tandem with Doppler broadening spectrometer for non-destructive depth profiling studies in thin films and interfaces.

Perturbed angular correlation
Indigenously built TDPAC spectrometer which consisting of a four detector fast-slow coincidence system using BaF2 detectors with a time resolution of 0.6ns
FTIR Spectroscopy
Built around a BOMEM DA-8 FTIR spectrometer that operates over an extended range of 10 cm
Positron Lifetime spectroscopy
When the energetic positron enters solids, gets thermalised, diffuses and ultimately annihilates with an electron. The time spent by the positron in the solid depends on the local electron density around the annihilation site
Coincidence Doppler Spectrometer
This recently commissioned spectrometer reduces the background of gamma ray energy spectrum by three orders of magnitude, enabling the positron spectrometry to identify chemical environment of defects and defect-impurity complexes.
Auger Electron Spectroscopy
This spectrometer is based on OMICRON-make Auger CMA-100 system with an energy resolution of 0.4% and has in-situ heating and sputtering options.
