Advantages of axially aligned crystals used in positron production at future linear colliders

Advantages of axially aligned crystals used in positron production at future linear colliders

The characteristics of the electron-photon showers initiated by 2 to 10 GeV electrons aligned along the ⟨111⟩ axis of tungsten crystals are compared with those for the amorphous tungsten. In this energy range, as known, the positron yield at the optimal target thicknesses is larger in a crystal case...
