Electron Capture and Ionization of Pb Ions at 33 TeV

Abstract: We have measured the total cross sections for electron capture by bare Pb 821 ions and ionization of hydrogenlike Pb 811 ions at 33 TeV (160 GeV͞A, g 168) in solid targets of Be, C, Al, Cu, Sn, and Au. The total capture cross sections are dominated by electron capture from pair production and are compared with theoretical calculations. The 1s ionization cross sections obtained are significantly smaller than those predicted by Anholt and Becker [Phys. Rev. A 36, 4628 (1987)]. The Pb radiative lifetimes extended… Show more

“…It is therefore vital to test our quantitative understanding of the features of the BFPP process in order to ensure safe operation of the LHC, uninterrupted by lengthy quenchrecovery procedures. BFPP has been measured in fixed target experiments [9][10][11] at lower energy but not, until now, in a collider. An opportunity arose during 63 Cu 29 operation of RHIC at Brookhaven National Laboratory.…”

“…The probability to eject a K-electron is much larger than for other atomic orbitals. Recent experiments have reported ionization cross sections for P b 81+ (33 TeV) beams on several targets [7]. In this case, the role of projectile and target are exchanged in the previous equation.…”

“…The data of Figure 1 can be used to determine both the capture cross section (σ c ) and the cross section for electron loss (σ i ) by fitting the data using a two-state model [6]: As mentioned in the introduction three different reaction mechanisms contribute to the total capture cross section. Each of the processes has a different scaling behaviour relative to the target atomic number (Z T ) and the relativistic Lorentz factor of the incoming ion (γ).…”
