COOLER As a consequence of the short muon lifetime, traditional cooling techniques are inappropriate, so the required phase-space reduction is achived by means of ionisation cooling. This involves passing the muon beam through a material in which it loses energy through ionisation and then re-accelerating the beam in the longitudinal direction to replace the lost energy. The IDS-NF baseline calls for lithium-hydride absorbers embedded in a solenoidal transport channel with re-acceleration achieved using 201 MHz cavaties at a gradient of 16 MV/m.
