/ Kröger, F M (U. Jena (main) ; Helmholtz Inst., Jena) ; Weber, G (Helmholtz Inst., Jena ; Darmstadt, GSI) ; Shevelko, V P (LPI, Moscow (main)) ; Hirlaender, S (CERN) ; Krasny, M W (CERN ; Paris U., VI-VII) ; Stöhlker, Th (U. Jena (main) ; Helmholtz Inst., Jena ; Darmstadt, GSI)
We present charge‐state evolution studies for Pb$^{54+}$ ion beams passing through stripper foils at relativistic energies of 5.9 GeV/u. The purpose of this investigation is to determine the optimum target material and non‐equilibrium thickness for the efficient production of few‐electron lead ions, that is, Pb$^{80+}$ and Pb$^{81+}$, at the present European Organization for Nuclear Research, CERN, accelerator facility at energies as high as 5.9 GeV/u.

An improved design of a longitudinally sensitive resonant Schottky cavity pickup for the heavy ion storage rings of the Facility for Antiproton and Ion Research in Europe (FAIR) project is reported. The new detector has a higher measured Q value of ∼3000 and a higher simulated shunt impedance of 473.3 kΩ. [...]

Charge-state distributions of highly charged lead ions at relativistic collision energies
/ Kröger, Felix M. (Jena U. ; Helmholtz Inst., Jena ; Darmstadt, GSI) ; Weber, Günter (Helmholtz Inst., Jena ; Darmstadt, GSI) ; Hirlaender, Simon (U. Salzburg (main)) ; Alemany‐Fernandez, Reyes (CERN) ; Krasny, Mieczyslaw W. (CERN ; Paris U., VI-VII) ; Stöhlker, Th. (Jena U. ; Helmholtz Inst., Jena ; Darmstadt, GSI) ; Tolstikhina, Inga Yu. (LPI, Moscow (main)) ; Shevelko, Viacheslav P. (LPI, Moscow (main))
Presented is a study of the charge-state evolution of relativistic lead ions passing through a thin aluminum stripper foil. It was motivated by the Gamma Factory project at CERN, where optical laser pulses will be converted into intense gamma-ray beams with energies up to a few hundred MeV via excitation of atomic transitions in few-electron heavy-ions at highly relativistic velocities.

BREIT code: Analytical solution of the balance rate equations for charge-state evolutions of heavy-ion beams in matter
/ Winckler, N (Darmstadt, GSI) ; Rybalchenko, A (Darmstadt, GSI) ; Shevelko, V P (Lebedev Inst.) ; Al-Turany, M (CERN ; Darmstadt, GSI) ; Kollegger, T (Darmstadt, GSI) ; Stöhlker, Th (Darmstadt, GSI ; Jena U. ; Helmholtz Inst., Jena)
A detailed description of a recently developed BREIT computer code (Balance Rate Equations of Ion Transportation) for calculating charge-state fractions of ion beams passing through matter is presented. The code is based on the analytical solutions of the differential balance equations for the charge-state fractions as a function of the target thickness and can be used for calculating the ion evolutions in gaseous, solid and plasma targets.
