  A significant number of high power proton beams are available or will go
online in the near future. This provides exciting opportunities for new fixed
target experiments and the search for new physics in particular. In this note
we will survey these beams and consider their potential to discover new physics
in the form of axion-like particles, identifying promising locations and set
ups. To achieve this, we present a significantly improved calculation of the
production of axion-like particles in the coherent scattering of protons on
nuclei, valid for lower ALP masses and/or beam energies. We also provide a new
publicly available tool for this process: the Alpaca Monte Carlo generator.
This will impact ongoing and planned searches based on this process.
