CH Outline

- 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:
