    "abstract": "The chopping line is a critical part of the ESS linac in term of technical\nrealisation of the choppers and preservation of the beam qualities. A new\noptimised design of the ESS RFQs and chopping lines is reported. The beam\ndynamics has been optimised with H- beam currents up to 100-mA to have safety\nmargin with respect to the ESS goals. The first RFQ transmits almost 99.7% of\nthe beam up to 2 MeV. The line with two choppers allows a perfect chopping\nbetween 2 bunches. The second RFQ accelerates the particles up to 5 MeV with a\ntransmission close to 100%.",
