What to expect

Post by DustBuster »

Greetings!

In the training focus movies, it seemed most particle track examples came from a nearly head-on impact (at least from the VM's view angle, and as compared to the focus movie from the Russian space station sample; which seemed like an angular impact).
What should we expect from samples we will examine?
Is there a 'rule-of-thumb' for "This looks interesting"?

Kind of. I've worked with similar slides in biology, looking for voids where small nematode worms ate through a gel. Generally, you will see a high-contrast void, that persists and slides along as you raise and lower the focus through the gel.

The strongest indication of a track will be a nice circular/oval/elliptical shape that persists through the focus range. Bonus feature would be a nice dark little particle deeper in the gel.

Looks like petroscope images to me. Well, uncrossed polar images. The relief seems the same. Was polarized light used in the microscope images?
