The Joint European Torus (JET) Team has studied experimentally the use of beryllium as a material for walls and limiters. The experiments compare the plasma performance of evaporated beryllium layers and massive beryllium limiters with that of graphite. The use of beryllium is generally beneficial, and fusion rates >8 × 10²⁰ m⁻³-keV·s are reached. The results of the beryllium operation are summarized.
