“…Another challenge for applying plasma accelerator into the electron-positron collider is that positron cannot be accelerated in bubble since they experienced and defocusing force [11]. the quality of the positron beam would be strongly reduced in the process of high-gradient plasma wake field acceleration for the positron beams, whatever method is used.…”

Contemporarily, the collider plays a vital role in research and analysis for high energy physics, particle physics and astrophysics. However, conventional colliders usually need a large budget to operate as well as cover a large area for displacing the facility. With the rapid development of the laser techniques, the laser-plasma accelerator paves a path to accelerate particles in a compact way. On this basis, this paper will analyze the feasibility and recent progress for electron-positron collider realization via the concept of the laser-plasma acceleration. To be specific, the principles behind it will be analyzed initially. To be specific, an intense electromagnetic could make the plasma oscillated due to the pondermotive force, and the electron field created by the oscillation of the plasma could accelerate electrons to high energy. In addition, the possibility of applying laser plasma acceleration in to electron-positron collider is examined. These results shed light on guiding the further exploration of future electron-positron collider.

“…Therefore, the plasma-based accelerators can greatly reduce the footprint of future accelerators and their associated construction and operation cost. It is envisaged that the plasma-based accelerators will find many applications in providing high quality particle beams for free electron lasers [4][5][6][7] , fixed target experiments and energy frontier colliders [8][9][10][11] .…”

The computational cost of finding the optimal design of plasma wakefield acceleration (PWFA) is usually very demanding due to many variables involved. Herein, we have developed a novel framework which combines Bayesian Optimization (BO) with neural network (NN), to replace computationally expensive simulation software and provide a more efficient way for the optimization process. In order to verify this framework, the AWAKE Run 2 experiment at CERN is used as an example. In the framework we constructed, the coefficients of determination (R2) of NN reaches above 0.99, and the time-to-solution reduces to a factor of 18.6. For the first time, BO combined with NN is successfully applied to optimize PWFA and significant improvements have been demonstrated. The framework established here in principle can also be extended to the optimization of other particle accelerations.

“…It is precisely in cost reduction that PWFA could play a decisive role. The very high gradients attainable promise a significant reduction in the length of the main linear accelerator and hence a concomitant reduction in cost [41]. While there is realistic hope that a particle-physics-oriented PWFA electron accelerator could soon be a reality, no analogous situation currently pertains for a plasma-based positron accelerator.…”

The construction of an electron–positron collider “Higgs factory” has been stalled for a decade, not because of feasibility but because of the cost of conventional radio-frequency (RF) acceleration. Plasma-wakefield acceleration promises to alleviate this problem via significant cost reduction based on its orders-of-magnitude higher accelerating gradients. However, plasma-based acceleration of positrons is much more difficult than for el ectrons. We propose a collider scheme that avoids positron acceleration in plasma, using a mixture of beam-driven plasma-wakefield acceleration to high energy for the electrons and conventional RF acceleration to low energy for the positrons. We emphasise the benefits o f a symmetric e nergies, a symmetric b unch charges a nd a symmetric t ransverse emittances. The implications for luminosity and experimentation at such an asymmetric facility are explored and found to be comparable to conventional facilities; the cost is found to be much lower. Some of the areas in which R&D is necessary to make HALHF a reality are highlighted, including estimates for the improvement required in key technologies. These range from a factor of 10 to a factor of 1000.
