This focusing horn was developed in 1992 by Remo Maccaferri, Jean Claude Schnuriger and Lubrano di Scampamorte and is still operating in the AD complex at CERN (as of 2017). This device could pulse at 400 KA (160 KA for the previous version). This enabled an antiproton collection ten times better than the old one. Firstly, protons were accelerated to an energy of 26 GeV/c and ejected onto a metal target. From the spray of emerging particles, the magnetic horn picked out 3.6 GeV antiprotons for injection into the AA through a wide-aperture focusing quadrupole magnet. For a million protons hitting the target, ten antiprotons were captured, 'cooled' and accumulated. It took 3 days to make a beam of 3 x 10^11 - three hundred thousand million - antiprotons. Originally magnetic focusing horns were developed by Simon van der Meer - see for example object AC-022 in this database.
