The diamond detector is not behaving properly |
|
|
On the image attached we can see the counting rate of the diamond (Red) going up linearly while Vamos (blue) staty stables.
This is understood as the diamond's graphite impurities charging up with the beam, so the baseline is moving up and we trigger more and more on noise. At some point I expect the counting rate to start dropping as the detector is no longer polarized. |
