- Damaged vs undamaged materials
- 1D doppler broadening using PAS - talk to Chuting about sourcing materials
Talk about measurement, why measure it, prediction on how well you can measure it
Goals:
Investigate defects in previously damaged materials using positron annihilation spectroscopy.
Determine the change Doppler broadened peaks in damaged materials throughout the annealing process.
Outcomes:
Quantify the annealing process by analysis of the change in Doppler broadened peaks.
(as damage lessens throughout annealing process, the 511KeV peak should become sharper)
Benefits:
