Performing Integrated WDS and EDS Acquisition in PFE

[JonF]

As we have mentioned previously the JEOL PC-SEM software automatically inserts the PCD (Faraday cup) after the EDS spectrum acquisition is complete (it's a feature not a bug!). 

In order to prevent the Faraday cup from being inserted before the WDS acquisition finishes (if it is using a longer acquisition time than the EDS), one must be sure to *uncheck* the "Insert PCD after the reservation execution is completed" checkbox in the JEOL software:

This came up elsewhere whilst discussing combined WDS/EDS using the older JEOL EDS interface as on the 8230/8530F EPMAs (i.e. PC-SEM as opposed to SEM Centre).

If you are doing combined WDS/EDS, you need to make sure that you have set PCD to "OFF" in the EDS Acquisition Condition window for both Spectrum and Multi Points. You can see this menu in PC-SEM in the Analysis tab, and the Condition button on the bottom right of the PC-SEM screen (in the EDS part of the window).

This will prevent the EDS from closing the PCD whilst PfE is still collecting data from the WDS (if the EDS time is less than the WDS time).
