Advanced spectroscopy experiments and new physics experiments with positronium atoms in vacuum will benefit from positronium production in an environment free of magnetic and electrostatic fields. Here. we present a novel scheme for generating a bunched positron beam. The positron bunches are prebunched before extraction from a buffer-gas trap. https://www.markbroyard.com/top-super-pet-naturals-busy-butter-calming-peanut-butter-for-cheap-limited-save/
