9 Turning On Apollo Press and Release the Power Button12/11/2017 Turning On Apollo Press and Release the Power Button Fan will turn on immediately After ~15s, system screen will turn on and show self-test messages Boot will take longer if the temperature is too hot or cold as the detector temperature needs to normalize before it biases up Screen will display a biasing- up message with a count down until it is ready to record data If using the tablet, similar messages will be displayed on the tablet as on the screen 9 9

10 Modes of Operation Search Mode: Localization Mode:12/11/2017 Modes of Operation Search Mode: Apollo searches for isotopes using only counts recorded in the previous 1 minute No imaging (localization) is performed Data is not saved to USB drive Localization Mode: Apollo localizes isotopes in its field of view Data saved to USB drive Detector need to be held stably for duration of measurement If moved, the image will be invalid (blurred) Stop measurement before moving the system 10 10

11 Localization Procedure12/11/2017 Localization Procedure Set Apollo in Search Mode Align optical field of view to cover the area of interest Press red power button to start new measurement Wait for data to be collected Once measurement is complete (has sufficient statistics for each isotope of interest), press red power button to stop measurement Repeat steps 1-5 in next area of interest 11 11

15 Thermal Management Considerations12/11/2017 Thermal Management Considerations CZT detector thermally regulated to hold at 30°C Apollo will automatically turn off if the internal temperature reaches 104°F (40°C) When turning on Apollo, the system will wait until the CZT temperature is between 25°and 35°degrees C before biasing up This may take a few minutes as Apollo heats/cools the detector to the appropriate temperature 15 15

16 12/11/2017 Shutting Down Apollo Shutting down Apollo properly will minimize the risk of system errors Two methods for shut down Push the red power button firmly for 4s.

30 “Best Practices” for operation12/11/2017 “Best Practices” for operation Give each measurement a name If using measurement button, rename measurement in Visualizer Use a common convention that everyone uses at your site Add measurement notes For quantitative analysis, record the source-to-detector distance Notes useful for other users looking at your data Notes can be searched in Visualizer Stop measurement before moving system Before doing this, make sure each isotope you care about has the image quality you desire 30 30

31 12/11/2017 Energy Calibration H3D guarantees the energy calibration for the first 2 years. Can be extended through the warranty extension. To check the calibration: Place check source directly in front of system; if isotope is not in Polaris-H library, please add it in advance Confirm isotope is automatically identified by Polaris-H If isotope is not identified by name, please contact H3D for support Re-calibration requires return of the system to H3D. If available and necessary, H3D will provide a replacement system during the time your system is returned to H3D for recalibration. 31 31
