A new record has been set for the longest period of beam delivery without interruption. This took place during the last week of the last run for 2004. The beam was maintained for 288 consecutive hours without a trip despite operation in 16-bunch filling pattern. This pattern requires 48 re-injection operations, each followed by a special bunch "cleaning" operation to remove the unwanted buckets, leaving a contrast ratio higher than 1E-7 between the main and adjacent buckets. Many thanks to the operation group and all intervening staff.
