Figure 1: EDS Detector configuration window, click on spectrum icon to see this.
- Use the arrow icon on the bottom left corner of the EDS configurator (Figure 1) to open the EDS Detector Configuration dialogue and set Pulse throughput and Maximum energy to Automatic. Check that the detector temperature status indicator is green.
- Note the input count rate (ICR) in the EDS detector configuration box. This should be between 1.0-10 kcps (thousand counts per second) at minimum, and instructions to adjust microscope parameters to increase counts are in the following section. If the input count rate is too low, try the following steps.
- Verify that the SEM is operating with a working distance of 7-10 mm (Focus area of Nanoeye software)
- Adjust the position of the second condenser lens (CL2 in the EDS menu of the Nanoeye software)
- Consider increasing the accelerating voltage of the SEM, up to a maximum of 20 kV. Note that this may increase the undesireable effects of built-up electric charge, which diminishes image and EDS quality.
- Ask a technician for help with aligning the strip aperture and aligning the electron gun.
