Scotch Tape -vs- Kapton tape

A 20 MeV electron was used to make a bremsstrahlung beam that impinged a sample of regular Scotch Tape and Kapton tape. Both tapes had similar areas of 2.5 x 3 cm. The Kapton had twice as much mass as the Scotch (0.1247 g -vs 0.0699 g).

The scotch taper became brittle after 4 hours of irradiation on the 25 N machine.

Below is an uncalibrated spectrum using Thorium rods. Lines should appear at 238.8,338.8, 511, 583.4, 911.2, and 2614.6 keV


Channel Energy (keV)
242 238.8
342 338.8
514 511
586 583
914 911.2
2617 2614.6

slope=1.0003 +/- 0.000156023 y-intercept=-3.12645 +/- 0.185346

MPA->Draw("-3.12645+1.0003*evt.Chan>>(8000,0,8000)");

Scotch tape run was 6663.4 seconds long (MPA->Draw("-3.12645+1.0003*evt.Chan>>NScotchTape(8000,0,8000)","0.00015");)

Kapton Tape run was 488.44 seconds long (MPA->Draw("-3.12645+1.0003*evt.Chan>>NKaptonTape(8000,0,8000)","0.0020473344");)
