Figure 3
(a) Threshold scans for electron detection at three different electron energies: 8 keV, 15 keV and 20 keV. Full symbols represent data taken with the standard X-ray Si sensor covered with an Al layer, empty symbols are for the sensor without the Al layer. (b) Derivative of the threshold scan curve. The improvement in the detection of electrons removing the Al layer is clearly visible. (c) Derivative of a threshold scan for 15 keV electrons in the `trimmed' and `untrimmed' settings.
