The chart of beams presents the stable beams available in one laboratory or more participating in ECOS collaboration. Other laboratories from this collaboration will be considered as soon as their beams data are provided to the team in charge of the development of the chart.

    1) When you open for the first time the chart, the isotopes are presented in three colors :
    1. Black : stable beams produced in one laboratory or more,
    2. Gray : stable isotopes beams unavailable in any laboratory,
    3. White: radioactive isotopes.


    2) When you put the mouse over any stable isotope you obtain some information about its production on a frame showing the laboratories where it is produced and the maximum of the energy of the production.


    3) When you click on any “black” isotope (112Sn for example) a new window opens.

    This window presents data (on tables) of the beams of all isotopes for the same element (112Sn, 114Sn, ...) concerning each laboratory. You can download in pdf format these data files for each laboratory by clicking the pdf logo.



By clicking on this icon on the left of the chart you can show or to hide the legend.

The Legend allows choosing of three options concerning the stable beams:

When you select a laboratory (or more) the chart shows all the beams produced by this selected laboratory (or laboratories).

You have to click on "Beam Energy MeV/u" to activate the cursor of the energy.

  1. If "Display energy range" is activated, the chart shows the stables beams produced at all energies less than or equal to the value of the energy selected by the cursor (Example : when the cursor selects 350 MeV/u the chart shows the beams produced at the energies <= 350 MeV/u).


  2. If "Display energy range" is not activated, the chart shows the stables beams produced at exactly the energy selected by the cursor (Example : when the cursor selects 350 MeV/u the chart shows the beams produced at the energy 350 MeV/u).

You have to click on "Beam intensity pps" to activate the cursor of the intensity. The cursor of the intensity is activated only if the cursor of energy is also activated AND “Display energy range” is inactivated. This cursor allows to show the beams produced at the intensity selected by the cursor of the intensity AND the energy selected by the cursor of the energy.

The "Energy color scale" is the reflection of the cursor of the energy :

  1. The bar of the "Energy color scale" indicates the energy value selected by the cursor of the energy.
  2. The minimum and the maximum of the cursor of the energy are shown on the "Energy color scale" by two arrows.
