Stone kapton straw
Pristine
The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O. White spots are Ca = C = O > Al > P
Under source (irradiated)
The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O . The X-ray analysis of a dark spot gave C = 0 > Al. Also the darker the spot the more O present.
3 years under voltage (big prototype)
The relative X-ray analysis of a normal area gave three peaks C, Al, and O. The magnitude of the peaks compared as C > Al > O, also the darker areas gave the same relative C > Al > O.
Lamina thin straw
The relative X-ray analysis of a normal area (light gray) gave three peaks C, Al, and O. The magnitude of the peaks compared as Al > C > O. The dark spots showed O > Al > C or O = Al > C . White spots are Ca = C = O > Al > P
Lamina thick straw
The relative X-ray analysis of a normal area gave one peak: Al. The white dots are Fe
