“In 1982 a MoU was signed by GSI, Darmstadt, CERN and LBL Berkeley to get heavy ions to CERN: GSI promised to bring an ECR-ion source and LBL a RFQ Linac to the CERN site. Rudolf Bock(GSI), Herrmann Grunder (LBL) and Reinhard Stock (Uni Marburg) and others proposed to have heavy ions in the CERN PS. Robert Klapisch, then research director of CERN, found SPS more adequate and this lead to heavy ion physic[s] with Oxygen beams in 1986, sulphur beams in 1987 and lead beams in 1994.

In 1983 at the relativistic heavy ion meeting at Brookhaven, I discussed with Carlo Rubbia topics of the future heavy ion collider at BNL, later called RHIC, when he told me: ‘You will get your collider at CERN, with enough energy for your physics case’

A few years later, a proposal for a heavy-ion programme was submitted in the LHC project . Rubia, kept his promise and among many things he insisted on a two-in-one magnet solution for the LHC instead of a pp_bar mode with only one vacuum chamber (what’s the benefits of this architecture? One vacuum chamber and one magnet is only good for ppbar, an option several persons preferred since it was also cheaper ).

From 1991 on, a group of about 20 persons met at CERN regularly to work on a proposal for a dedicated heavy ion experiment at the LHC. In parallel we had to build and run our lead beam experiments at the SPS. ”

And, so it goes in HEP. Read the full article here.
