As described in The Moon is a Harsh Mistress (great book), a linear accelerator would be great for the moon. Earth’s gravity is too high & atmosphere too dense for accelerators to be a good solution vs reusable boosters imo.

Ignition by John Clarke, Huzel & Wang book on propulsion, Asimov's Foundation, [and] Heinlein's MiaHM [are my favorite books about space.]
