IntroductionWhile an isotopic measurement is running, this window is the central anchor. It displays which BLOCK and which RUN is currently being executed and it allows real-time changes to these parameters. In addition, there are several subwindows that can be accessed from here that are useful to watch the progress of the measurement. This window has appears in two different modes: The 'Hysteresis Loop' mode and the 'Block Loop' mode, both of which are shown above. |
|
|
|
|
|
Hysteresis LoopAt the beginning of the first run, the magnet is cycled
10 times through all the masses. If so desired the number of
these hysteresis loops can be changed at any time during the
execution. The primary ion beam is usually off at this time.
During the hysteresis loops, the current mass peak display
is continuously updated: |
|
|
|
|
|
Run NumberHere the number of the current run is shown together with the total number of runs chosen. The total number can be changed at any time during the execution, but (of course) cannot be any lower than the current run number. |
|
|
|
|
|
Block NumberAfter the initial hysteresis loop, the window mode changes to the 'Block Loop' mode as shown above. Here the program performs repeated measurements for each block as defined during the setup. As with the run number, it is possible to change the total number of blocks at any time. The displayed 'Block# 0' is a special case for certain startup routines (e.g. manual calibration). The acutal data collection starts with 'Block# 1'. |

|
View Data FilesUp to three different data files can be created during a measurement. It is possible to watch what is written into those files in real time by clicking on these buttons. Buttons for file types that have not been selected during the setup will show up dimmed out and disabled. For a description of the data file viewing see Section 18. |
|
|
|
|
|
View GraphsIt is possible to watch graphical displays of various parameters in real time during the measurement by clicking on these buttons: Counts/Ratios: Watch the development of count rates and signal ratios over the course of the measurement. For a detailed description see Section 17. B-Field Shift: Monitor the shift of the magnetic field positions of different mass peaks that are being tracked. For a detailed description see Section 16. HV Offset: Not relevant for isotopic measurements. |

Show Results of Last...During a measurement the windows for the automatic mass centering and the determination of the energy edge briefly pop up and disappear again. To view the results of one of these previous routines, click on one of these buttons. Please note that these windows are completely static and do not automatically update with the execution of a new centering routine. Click on "Update" to manually update the display in these two windows. |

|
Option: Allow PrintingSimple Printing on-off switch. Independent of the selection in IsoSetup 3 it is here possible to turn off the printing on the ThinkJet Printer. Once turned off, it cannot be turned on again from here. This option is 'on' by default. |
|
|
|
|
|
Option: Show Peak CenteringBy default the peak centering and the energy edge determination windows pop up whenever necessary during the run. To prevent these windows from showing up, deselect this option. This option can be changed back and forth as desired. |
|
|
|
|
|
Time InformationHere the total time elapsed and the projected time for the entire run are displayed. The latter is not yet implemented. |
|
|
|
|
|
AbortThis aborts the measurement after finishing the current step. All data files will be closed, but the information in those files may not be complete. The abort option should also work during an automatic peak centering routine; if there is a problem with the secondary ion signal and the peak cannot be found, click abort to cancel this run. |
