    "abstract": "The Storage Ring at the Advanced Light Source is capable of being filled in\nselectable buckets. Typically, 276 consecutive buckets out of 328 possible are\nselected. It has been found that the amount of charge injected is not uniform\nbucket-to-bucket, sometimes varying by 100% or more. This variability causes\nproblems with beam stability, and it may shorten the beam lifetime. We have\ndevised a feedback system that allows for beam filling in an orderly manner,\nyielding bunch heights uniform to within 17%. At fill time, multiple bunches\nare injected into the Storage ring first, then, using feedback, selected single\nbunches are used to top off the fill.",
