Inspection with an optical microscope
From GlueXWiki
- All features that appeared in lines are in the direction of the wire spiral.
- Microscope has a light source underneath the sample
Stone kapton straw
Although it appears the the straw that was irradiated shows more holes - It appears to me that it depends more on the piece of straw (chance) than irradiation (as this effect is not seen in the Lamina-thin straw).
Lamina thin straw
No extra holes after irradiation are observed.
Lamina Thick straw

The straw is not transparent for light. The same results were obtained with light (underneath the sample) on/off.
