Control the Run Statistic

The statistic accumulated into the histograms as well as in the scalers can be checked when the tab pTA Status selected.
The first table shows the Histograms ("H"), with the current values ("C") and the saved values ("S"). Also the actual rate of the histograms is shown ("rH").

The second table shows the Scalers ("S"), with the current values ("C") and the saved values ("S"). Also the actual rate of the scalers is shown ("rS").

deltat main window with the pTA Status tab selected.

On the same tab pTA Status the button pTA Scalers gives acces to a graphical representation of the present scalers rates.

Stop a Run

When the desired statistic has been reached, the run can be stopped by selecting the tab Run Control and by hitting the button Stop Run . At this point the user can still modify the titles of the stopping run.

This action is possible by selecting the tab Run Control and by hitting the button Zero Run . A confirmation dialog will appear at this point.

Kill a Run

Although this action should be limited to the strict minimum, the user has the possibility to "kill" an active run. This action will delete all the data files connected to this run and clear the content of the scalers and histograms.
This action is possible by selecting the tab Run Control and by hitting the button Kill Run . A confirmation dialog will appear at this point.

Modifying Experimental Parameters

The experimental parameters can be modified, as a rule, when a run is not active.
