X

The energy of the X-rays is not the same for every photon but forms a continous spectrum. The exact distribution thereby depends on the operation voltage. The maximum energy of a X-ray photon measured in keV matches the operation voltage measured in kV but most photons have lower energies.

 Operating Instructions:

In this screen experiment different devices for measuring X-rays will be tested at varying operation voltage.

  • Using the arrow-buttons you can choose the measuring device.
  • To change the operation voltage, first open the magnified control panel by clicking somewhere in the operation field of the X-ray tube. Now select the voltage setting with the button "U". By using the setting dial or clicking on the voltage display you then can choose a voltage between 0 kV and 35 kV.
  • To start or end a measurement, use the button "HV On/OFF" in the lower right of the control panel.

How do you explain your results? If necessary you can get a hint by using the corresponding button.
