XTDX: Mobile dumps

XTDX are mobile dumps, used in the experimental halls to isolate a downstream area from an upstream one. Typically access to the upstream area is controlled by magnets (and sometimes TAX dumps as well). The access to the downstream area may under certain conditions be controlled by a single motorised dump like the one shown below.

The zone behind the XTDX can only be liberated for access if the beam intensity impinging on the XTDX is below a given limit, specified by Radioprotection service. This limit is never above 106 particles per SPS cycle.
