First High-Intensity Beam Tests with Telescopic Flat Optics at the LHC
The paper reports on the first high-intensity beam tests obtained with flat optics in 2018 (MD2148). This new machine configuration is described in terms of hypercycle, optics transitions, and dedicated beam gymnastics. The various commissioning steps which were needed to obtain the green light for an...

description | The paper reports on the first high-intensity beam tests obtained with flat optics in 2018 (MD2148). This new machine configuration is described in terms of hypercycle, optics transitions, and dedicated beam gymnastics. The various commissioning steps which were needed to obtain the green light for an intensity ramp up are highlighted, in particular the optics measurements and corrections, the triplet aperture measurements, and the collimation-related activities. First collision of trains took place in the second 2018 LHC MD block. The main results are given in terms of luminosity, long-range beam-beam mitigation with lattice octupoles, and corresponding crossing angle reach. |
