Align Zero Loss Node Class¶
AlignZeroLoss class is used to align the energy filter slit so that zero loss peak is allowed to pass through optimally. It is used with Gatan Energy Filter such as Bioquantum series. At given interval and optionally below an intensity threshold, the alignment process is initiated.
Reference target requirement:¶
The alignment requires an area that either empty or with little obstruction. This reference target stage position must be defined for the node to function.
Bindings¶
Required Binding for initiate the time interval check and alignment
Acquisition -> AlignZeroLossPeakPublishEvent -> Align Zero Loss Peak
*When phase plate aligner is used for phase plate, bind phase plate aligner with align zeo loss peak to force zero loss peak alignment at each phase plate patch change.
Phase Plate Aligner -> FixAlignment -> Align Zero Loss Peak
Required Binding for moving to reference target
Align Zero Loss Peak ->ChangePresetEvent -> Presets Manager
Presets Manger -> PresetChangedEvent -> Align Zero Loss Peak
Align Zero Loss Peak -> MoveToTargetEvent -> Navigator
Navigator -> MoveToTargetDoneEvent -> Align Zero Loss Peak
Reference Target Settings¶
- Bypass Conditioner should be deactivated for the node to be used.
Check Zero Loss Peak Shift Settings¶
- Set the standard deviation threshold to 0 if you want it to do alignment based only on time interval.
