Research Summary: The International Linear Collider (ILC), a proposed electron-positron accelerator with an estimated cost of $6.75 billion, aims to elucidate the fundamental natures of matter, energy, space, and time. The ILC consists of two main linear accelerators (linacs), each 14 km in length, for producing electron and positron beams with 250 GeV energies. This INCITE project will simulate the radio-frequency unit and the basic accelerator section in the ILC main linacs and evaluate the effects of wakefields and heat loads. The simulations will play an important role in ILC design by improving performance, increasing reliability, and lowering cost.
