Eigenvalue bounds for preconditioned symmetric multiple saddle-point matrices with block-triangular preconditioners
Luca Bergamaschi, Michele Bergamaschi, John W. Pearson
We develop eigenvalue bounds for symmetric, block-tridiagonal multiple saddle-point linear systems, preconditioned with block-triangular matrices, based on approximate Schur comple…

Experimental Observation of Motion of Ions in a Resonantly Driven Plasma Wakefield Accelerator
M. Turner, E. Walter, C. Amoedo +15
We show experimentally that an effect of motion of ions, observed in a plasma-based accelerator, depends inversely on the plasma ion mass. The effect appears within a single wakefi…

Measurement of the emittance of accelerated electron bunches at the AWAKE experiment
D. A. Cooke, F. Pannell, G. Zevi Della Porta +81
The vertical plane transverse emittance of accelerated electron bunches at the AWAKE experiment at CERN has been determined, using three different methods of data analysis. This is…
