Beam Tracking Studies of Electron Cooling in ELENA
/ Veglia, Bianca (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Hunt, James (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Resta-López, Javier (Cockcroft Inst. Accel. Sci. Tech. ; U. Liverpool (main)) ; Rodin, Volodymyr (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.) ; Welsch, Carsten (U. Liverpool (main) ; Cockcroft Inst. Accel. Sci. Tech.)
The Extra Low ENergy Antiproton storage ring (ELENA), which is currently being commissioned at CERN, will further decelerate antiprotons extracted from the Antiproton Decelerator (AD) from 5.3 MeV to energies as low as 100 keV. It will provide high quality beams for the antimatter experiments located within the AD hall. [...]

Electron coolers are commonly used in storage rings to reduce the phase space volume of heavy particles such as protons, antiprotons and ions. Their effect depends on the Coulomb interactions between the circulating beam and the cold electrons at small relative velocities. [...]

Tanning of leather for clothing, shoes, and handbags uses potentially harmful chemicals that often run off into local water supplies or require a large carbon footprint to safely recover these pollutants. In regions of the world with significant leather production, this can lead to a significant environmental impact. [...]

Development of a Fluorescence Based Gas Sheet Profile Monitor for Use With Electron Lenses: Optical System Design and Preparatory Experiments
/ Udrea, Serban (Darmstadt, GSI) ; Barrios Diaz, Elena (CERN) ; Chritin, Nicolas (CERN) ; Forck, Peter (Darmstadt, GSI) ; Jones, Owain Rhodri (CERN) ; Magagnin, Paolo (CERN) ; Schneider, Gerhard (CERN) ; Tzoganis, Vasilis (Cockcroft Inst. Accel. Sci. Tech.) ; Veness, Raymond (CERN) ; Welsch, Carsten (Cockcroft Inst. Accel. Sci. Tech.) et al.
A hollow electron lens is presently under study as a possible addition to the collimation system for the high luminosity upgrade of the LHC (HL-LHC), while an electron lens system is also proposed for space charge compensation in the SIS-18 synchrotron for the high intensities at the future FAIR facility. For effective operation, a precise alignment is necessary between the high energy hadron beam and the low energy electron beam. [...]
