Work progresses on Linac4, the linear accelerator foreseen to take over from the current Linac2 as injector to the PS Booster. On 5 August, the first drift-tube linac (DTL) tank saw beams at 12 MeV. After seven years of design, prototyping and manufacturing, the Linac4 DTL, which comprises three tanks, underwent countless workshop-based measurements of the geometry, vacuum and magnet polarization of the tanks, before the first was installed in the Linac4 tunnel on 5 June. Beam commissioning tests ran until 21 August, and found the DTL operating with nominal transmission.
