We present an update on the development of the new code for long-term simulation of beam-beam effects in particle colliders. The underlying physical model relies on a matrix-based arbitrary-order particle tracking (including a symplectic option) for beam transport and the generalized Bassetti-Erskine approximation for beam-beam interaction. The computations are accelerated through a parallel implementation on a hybrid GPU/CPU platform. With the new code, previously computationally prohibitive long-term simulations become tractable. The new code will be used to model the proposed Medium-energy Electron-Ion Collider (MEIC) at Jefferson Lab.

Luminosity is paramount in high energy physics research, therefore it is critical to optimize it. Particle beams are complex and orbit in a complicated fashion therefore they don't always collide as intended thus reducing our chance of discovery. Simulations and calculations of the beam-beam radiation or beamstrahlung can provide crucial insight into the collision geometry. Combined with an optics box that can collect and analyze this radiation, this could be an extremely valuable tool leading to correction of the …
