Stochastic Cooling Techniques: A new tool for heavy-ion collisions?

Q&A with John Jowett: New paths in Stochastic Cooling techniques

Hans H.Gutbrod recalls "How ALICE was born"

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 with Oxygen beams in 1986, sulphur beams in 1987 and lead beams in 1994

Reine and Michaela: Upgrading the LHC for asymmetric collisions

by Panos Charitos. Published: 22 January 2013

Reine Versteegen (CERN Fellow) and Michaela Schaumann (PhD Student) are closely working with John Jowett in the heavy-ion programme at CERN in getting protons and lead-ions colliding at the LHC. These asymmetric collisions pose technical challenges for the experiments related to numerous effects that appear due to the different charges and energies of the two beams. We met Reine and Michaela and discussed with them about their motivation and the challenges they faced before the proton-lead run.
