THPVA019	Self-consistent Space Charge Tracking Method based on Lie Transform	4454
	E. Laface, J.F. Esteban Müller ESS, Lund, Sweden
	In this paper we propose to describe the self-force of a particles beam, known as space charge, as an Hamiltonan term dependent on the distribution of the particles' coordinates: H_sc = H_sc(ρ(x,y,z)). This Hamiltonian is then used, together with the kinetic component H_k in a Lie transform to generate a transport map by e^{-L:H_k +H_sc}: where the Lie operator :H_k + H_sc: is defined according to the Dragt's notation [1]. Then the Lie transform is used to transport directly the distribution function ρ(x, y, z) in a self-consistent iterative algorithm. The result of this proof-of-concept idea is verified on a drift space and on a FODO channel and compared with a traditional multi-particles simulation code.

Self-consistent Space Charge Tracking Method based on Lie Transform

In this paper we propose to describe the self-force of a particles beam, known as space charge, as an Hamiltonan term dependent on the distribution of the particles' coordinates: H_sc = H_sc(ρ(x,y,z)). This Hamiltonian is then used, together with the kinetic component H_k in a Lie transform to generate a transport map by e^{-L:H_k +H_sc}: where the Lie operator :H_k + H_sc: is defined according to the Dragt's notation [1]. Then the Lie transform is used to transport directly the distribution function ρ(x, y, z) in a self-consistent iterative algorithm. The result of this proof-of-concept idea is verified on a drift space and on a FODO channel and compared with a traditional multi-particles simulation code.

The Open XAL accelerator physics software platform is being developed through an international collaboration among several facilities since 2010 The goal of the collaboration is to establish Open XAL as a multi-purpose software platform supporting a broad range of tool and application development in accelerator physics (Open XAL also ships with a suite of general purpose accelerator applications). This paper discusses progress in beam dynamics simulation, interaction with control system and software organization. We present the current status of the project, a roadmap for continued development and an overview of the project status at each participating facility.
