Lessons learned from the prototypes of the MQXFA Low Beta Quadrupoles for HL-LHC and status of production in the US
/ Ambrosio, Giorgio (Fermilab) ; Amm, Kathleen (BNL, NSLS) ; Anerella, Michael (BNL, NSLS) ; Apollinari, Giorgio (Fermilab) ; Baldini, Maria (Fermilab) ; Blowers, Jamie (Fermilab) ; Bossert, Rodger (Fermilab) ; Carcagno, Ruben (Fermilab) ; Cheng, Daniel W (BNL, NSLS) ; Chlachidze, Guram (Fermilab) et al.
With the successful test of the first two pre-series magnets the US HL-LHC Accelerator Upgrade Project has started production of the MQXFA magnets to be used in Q1/Q3 inner triplet elements of the HL-LHC. This good start comes after the test of two prototypes with limited performance, and it demonstrates the importance of learning from past issues. [...]

The High Luminosity (HiLumi) Large Hadron Collider (LHC) project has, as the main objective, to increase the LHC peak luminosity by a factor five and the integrated luminosity by a factor ten. This goal will be achieved mainly with a new interaction region layout, which will allow a stronger focusing of the colliding beams. [...]
