Measurements of charge state distributions of 0.74 and 1.4 MeV/u heavy ions passing through dilute gases
2017
In many modern heavy-ion accelerator facilities, gas strippers are used to increase the projectile charge state for improving the acceleration efficiency of ion beams to higher energies. For this application, the knowledge on the behavior of charge state distributions of heavy-ions after passing through dilute gases is of special interest. Charge state distributions of uranium ($^{238}\mathrm{U}$), bismuth ($^{209}\mathrm{Bi}$), titanium ($^{50}\mathrm{Ti}$), and argon ($^{40}\mathrm{Ar}$) ion beams with energies of $0.74\text{ }\mathrm{MeV}/\mathrm{u}$ and $1.4\text{ }\mathrm{MeV}/\mathrm{u}$ after passing through hydrogen (${\mathrm{H}}_{2}$), helium (He), carbon dioxide (${\mathrm{CO}}_{…
Applications of the pulsed gas stripper technique at the GSI UNILAC
2017
Abstract In the frame of an upgrade program for the GSI UNILAC, preparing it for the use as an injector system for FAIR, a pulsed gas stripper cell was developed. It utilizes the required low duty cycle by applying a pulsed gas injection instead of a continuous gas inlet. The resulting lower gas consumption rate enables the use of low-Z gas targets over a wide range of stripper target thicknesses. The setup enables an increased flexibility for the accelerator by allowing the gas stripper to be used in time-sharing beam operation matching the capabilities of the GSI UNILAC like the acceleration of different ion beams in quasi-parallel operation. Measured charge state distributions of 238 U, …
