The new accelerator facility FAIR is under construction at GSI. However, the experiments are carried out usually at energies about 300MeV/u. The ESR has a circumference of 108,36 m and a magnetic rigidity of 10 Tm. This cooling not only compensates the blowing-up of the beam but even increases its quality to so-called “brilliant beams”. ESR is an acronym for Electron Spin Resonance. Experiment 7 Electron Spin Resonance (ESR) 7.1 Introduction Using ESR (Electron Spin Resonance, also known as Electron Paramagnetic Resonance) you will be measuring one of the best known quantities in all of physics… ESR spectrometers developed for practical applications usu- ally work at frequencies of about 10 GHz (microwaves, X band). This is prevented by electron cooling, a process in which heat is taken out of the ion beam in collisions between the hot ions and cold electrons travelling at the same velocity. Thus, it is possible to store uranium ions at an energy of 560MeV/u. !!! When the molecules of a solid exhibit paramagnetism as a result of unpaired electron spins, transitions can be induced between spin states … Correspondingly, the magnetic fields are … The closed orbits of four ions with different charge to mass ratios m/q along the lattice of the ring are plotted. The strontium quantum gases group is headed by Prof. Florian Schreck and is part of the Quantum Gases and Quantum Information (QG&QI) cluster at the Institute of Physics … The ESR has a circumference of 108,36 m and a magnetic rigidity of 10 Tm. This determines the energy difference ∆E = hf = 2µB which, … In an ESR experiment the line width can supply information about many properties. Therefore, the ESR provides unique possibilities especially for experiments with the heaviest available ions.
