/ Hofmann, Thomas (Royal Holloway, U. of London) ; Boorman, Gary (Royal Holloway, U. of London) ; Bosco, Alessio (Royal Holloway, U. of London) ; Gibson, Stephen (Royal Holloway, U. of London) ; Roncarolo, Federico (CERN)
A laser-based emittance monitor has been developed to non-invasively measure the transverse emittance of the LINAC4 H⁻ beam at its top energy of 160MeV. After testing several sub-systems of the instrument during linac commissioning at intermediate energies, two instruments are now permanently installed. [...]

The CERN-ELENA Electron Cooler Magnetic System
/ Tranquille, Gerard (CERN) ; Jørgensen, Lars (CERN) ; Luckin, David (Tesla Engineering, Storrington) ; Warner, Rory (Tesla Engineering, Storrington)
Phase space compression of the antiproton beam in ELENA will be performed by a new electron cooler the performance of which is greatly influenced by the properties of the electron beam. Careful design of the electron gun electrodes, the efficient recuperation of the electrons in the collector and the quality of the guiding magnetic field ensure an optimal performance of the cooler. [...]

Commissioning the ELENA Beam Diagnostics Systems at CERN
/ Tranquille, Gerard (CERN) ; Burger, Stephane (CERN) ; Gąsior, Marek (CERN) ; Grandemange, Pierre (CERN) ; Levens, Thomas (CERN) ; Marqversen, Ole (CERN) ; Søby, Lars (CERN)
The Extra Low ENergy Antiproton ring (ELENA) at CERN entered the commissioning phase in November 2016 using H⁻ ions and antiprotons to setup the machine at the different energy plateaus. The low intensities and energy of the ELENA beam generate very weak signals making beam diagnostics very challenging. [...]

Comparison of Different Transverse Emittance Measurement Techniques in the Proton Synchrotron Booster
/ Di Giovanni, Gian Piero (CERN) ; Albright, Simon (CERN) ; Forte, Vincenzo (CERN) ; Fraser, Matthew (CERN) ; Guidoboni, Greta (EBG MedAustron GmbH) ; Mikulec, Bettina (CERN) ; Roncarolo, Federico (CERN) ; Santamaría García, Andrea (CERN)
The measurement of the transverse emittance in an accelerator is a crucial parameter to evaluate the performance of the machine and to understand beam dynamics processes. In recent years, controlling and understanding the emittance became particularly relevant in the Proton Synchrotron Booster (PSB) at CERN as part of the LHC Injectors Upgrade (LIU). [...]

Systematic Studies of Transverse Emittance Measurements Along the CERN PS Booster Cycle

The CERN Proton Synchrotron Booster (PSB) will need to deliver two times the current brightness to the Large Hadron Collider (LHC) after the LHC Injectors Upgrade (LIU) to meet the High-Luminosity-LHC beam requirements. Beam intensity and transverse emittance are the key parameters to increase brightness, the latter being more difficult to manipulate. [...]

Space Charge Studies on LEIR
/ Saá Hernández, Angela (CERN) ; Bartosik, Hannes (CERN) ; Biancacci, Nicolo (CERN) ; Hirlaender, Simon (CERN) ; Huschauer, Alexander (CERN) ; Moreno Garcia, Daniel (CERN)
The performance of the CERN Low Energy Ion Ring with electron cooled ion beams is presently limited by losses occurring once the beam has been captured in the RF buckets. An intense machine study program was started by the end of 2015 to mitigate the losses and improve the performance of the accelerator. [...]

LEIR Injection Efficiency Studies as a Function of the Beam Energy Distribution from Linac3
/ Hirlaender, Simon (CERN) ; Alemany-Fernández, Reyes (CERN) ; Bartosik, Hannes (CERN) ; Bellodi, Giulia (CERN) ; Biancacci, Nicolo (CERN) ; Kain, Verena (CERN) ; Scrivens, Richard (CERN)
High intensities in the CERN Low Energy Ion Ring (LEIR) are achieved using multi-turn injections from the pre-accelerator Linac3 combined with simultaneous stacking in momentum and transverse phase spaces. Up to seven consecutive 200 $\mu$s long, 200 ms spaced pulses are injected from Linac3 into LEIR by stacking each of them into the six-dimensional phase-space over 70 turns. [...]

Impedance and Instability Studies in LEIR with Xenon

In 2017, the LEIR accelerator has been operated with $Xe^{39+}$ beam for fixed target experiments in the SPS North Area. The different ion species, with respect to the standard $Pb^{34+}$, allowed for additional comparative measurements of tune shift versus intensity at injection energy both in coasting and bunched beams.

In 2017 the CERN Low Energy Ion Ring demonstrated once more the feasibility of injecting, accumulating, cooling and accelerating a new nuclei, $^{129}$Xe${39+}$. The operation of this new ion species started at the beginning of March with the start up of the xenon ion source and the Linac3. [...]
