In December 2018, a review of the design of the D2 correctors and HO correctors took place in CERN. The committee supported the selected designs that showed to reach the required performance. For the D2 correctors, based on the CCT concept that is being used at CERN for the first time, a special effort on documenting the magnet design with all novelties and details was suggested.

In March 2019, a review on the design of the D1 and D2 main magnets was carried out at CERN. The committee also supported the technical choices, pointing out the challenges related to the field quality. The inner triplet quadrupole and its nested corrector will be reviewed this summer
