Analysis of the MQXFA Low Beta Quadrupoles for HL-LHC after 50% magnet assembly complete +
The US HL-LHC Accelerator Upgrade Project (AUP) is fabricating the MQXFA magnets to be used in the Q1 and Q3 Inner Triplet elements of the High Luminosity LHC (HL-LHC). This is the first production of Nb3Sn magnets for a particle accelerator, together with the MQXFB magnets for Q2a and Q2b. Here we show status and some results of MQXFA magnets fabrication and vertical test.
