A planned upgrade, ALS-U (left and upper right), would replace this storage ring with a denser array of magnets, known as an MBA lattice, that would produce far brighter, steadier beams of so-called `soft' X-ray light. A unique secondary ring along the ALS's inner wall, called an `accumulator' ring, would rapidly replenish the energy in the main ring. (Credit: Berkeley Lab.) |
