Here's something that i am upto
It's basically a fixed amplitude detector. The test material has been to attached to a coil (76Ohm) which is constantly energised. The magnets are elctro-magnets configured to generate forced sine vibrations on the test material. The amplitude is calculated by the laser detector which can only detect a fixed amplitude. This system will be left operational for 100+ hours and the amplitude will be measured again (maximum value). This HAS to be done in STP at 100 hours things do get hot.
after this a sample will be cut out and it's value of Y and k measured, (as a ratio of the older values) hopefully if we get significant ratios this might prove that burn-in in fact is a physical process.
but then, i can only hope :)
