Summary: In this study, two new techniques for generating meter-scale, low-density plasma waveguides were presented. These techniques require the use of high-quality ultrashort pulse Bessel beams to efficiently and uniformly ionize hydrogen gas. The study also introduced a new method for correcting optical aberrations in Bessel beams and presented the results of recent experiments demonstrating the acceleration of electron bunches in low-density plasma waveguides.

Summary: We present a self-consistent theory of strongly nonlinear plasma wakefield (bubble or blowout regime of the wakefield) based on the energy conservation approach. Such wakefields are excited in plasmas by intense laser or particle beam drivers and are characterized by the expulsion of plasma electrons from the propagation axis of the driver. As a result, a spherical cavity devoid of electrons (called a bubble) and surrounded by a thin sheath made of expelled electrons is formed behind the driver. In contrast to the the energy conservation law, does not require any external fitting parameters, and describes the bubble structure and the electromagnetic field it contains with much higher accuracy in a wide range of parameters. The obtained results are verified by 3D particle-in-cell simulations.

Summary: Particle beam-driven plasma wakefield accelerators offer a significantly higher accelerating gradient compared to radio-frequency technology, making them crucial for future TeV energy colliders and x-ray free-electron lasers. The design of staged plasma accelerators, which aims to minimize interplasma distances, is one of the most important challenges in this field. In this study, a novel concept utilizing drive-beam coupling and femtosecond ionization laser gating is proposed to optimize the interplasma distances.

Summary: This article investigates the feasibility of using the MAX IV Linear Accelerator for PWFA experiments. The study finds that PWFA is a viable application for the linac, and the bunch compressor type employed in the MAX IV linac is well-suited for generating PWFA-optimized bunch current profiles.

Summary: This paper presents the first demonstration of multi-GeV laser wakefield acceleration in a fully optically formed plasma waveguide. In the experiment, an acceleration gradient as high as 25 GeV/m was achieved in a low-density hydrogen gas jet, with electron bunches of quasimonoenergetic peaks and relative energy width as narrow as 15%. The stability of bunch spectra and charge were found to be strongly dependent on the pointing of the injected laser pulse and gas jet uniformity.

Summary: This model examines the betatron oscillation and radiation reaction effects on an electron in a plasma wakefield accelerator, demonstrating good agreement between theoretical and numerical solutions. The discussion also includes the regime where quantum radiation becomes significant, highlighting the importance of this model for designing future plasma-based super accelerators or colliders.

Summary: This work presents a new approach for driving GeV-scale plasma accelerators using long laser pulses, modulating the temporal phase of a high-energy driver through controlled linear processes. Particle-in-cell simulations demonstrate the feasibility of accelerating electrons to 0.65 GeV energy using specific parameters in a plasma channel with high axial density.

Summary: Our study demonstrates the visualization of plasma bubbles driven by high-power laser pulses and the observation of optical changes caused by the acceleration of electron charges. The results indicate that different parts of the observed signals are related to high-energy electrons and trailing lower energy electrons inside the bubble.

Summary: In the Superconducting Demo Linac of the China Initiative Accelerator Driven Subcritical System project, a flashover caused by polarization energy relaxation around trapped electrons greatly limited the acceleration capability of the accelerator. By redesigning and applying a new antenna to the pick-up coupler, the abnormal signal caused by discharges during more than a year of cavity operation was successfully removed, improving the acceleration capability and stability performance of the accelerator.

Summary: This paper presents the design, configuration, and experimental results of the Rare-isotope Accelerator complex for ON-line experiments, which is a heavy-ion accelerator facility capable of accelerating stable or rare isotope beams up to 400 kW with an energy of 200 MeV/u. The Allison scanners, installed after the first dipole magnet (DM), are used to measure beam transverse emittance at the Low Energy Beam Transport section. Experimental Physics and Industrial Control System (EPICS) and an EPICS sequencer module are employed for device integration and control of the complex measurement sequence. Normalized emittance is calculated using python code with the Pyepics module and phase space distribution data.

Summary: A new regime of proton-driven plasma wakefield acceleration has been discovered, where the nonlinearity of plasma can increase the phase velocity of the excited wave, enabling the acceleration of electrons or positrons to about 200 GeV with a 400 GeV proton driver by adjusting the plasma density profile and beam charge.
