Computing Division achieves one petabyte of data in robotic storage
Last week, the automated tape libraries in Feynman Computing Center achieved a new milestone of accumulating one petabyte of data, an amount equal to one million gigabytes or one thousand terabytes. Scientists from CDF, DZero and other experiments and projects rely upon robotic storage to archive raw data as it is acquired from the detectors. Capable of storing up to six petabytes of data, the robotic storage already holds approximately thirty times the amount of data that was recorded during Run I. On an average day at Fermilab, approximately ten terabytes of data are transferred from experiments to robotic storage. To put this number into perspective, the entire Library of Congress, the largest library in the world with approximately 530 miles of bookshelves, is also equivalent to ten terabytes. With this statistic in mind, on any given day at Fermilab, the robotic storage transfers an amount of data that is approximately equivalent to the Library of Congress if not more.

New water reclamation system complete
The water reclamation system pumps water into two 2,800 gallon tanks.

NuMiís tunnel was dug 300 feet below the ground through an acquifer, a subsurface water supply for springs and wells. It is no surprise then that almost 350 gallons of water seep into the tunnel every minute. Until now, Fermilab pumped out and disposed the water into the Indian creek that empties into the Illinois river. But FESS decided that this water could be put to good use for the laboratory.

As a result, FESS designed a water reclamation system that pumps the water into two 2,800 gallon tanks. The water is then injected into the laboratoryís industrial cooling system used to cool magnets and air conditioning systems around the site. The project was completed on August 13. The reclaimed water will be particularly useful when the Fox River runs low and dry. At such times, by contract, Fermilab cannot use Fox River water.

Director's Corner
Good Morning!

Last Friday morning, August 22, just before 7 a.m., the operations crew in the Main Control Room watched as Store #2934 put the Tevatron's integrated luminosity above 225 inverse picobarns. It was an important moment for them and for Fermilab. Two hundred twenty-five inverse picobarns represents the number of particle collisions delivered to CDF and DZero this fiscal year. This number was Fermilab's goal, and an important measure for accelerator performance. Fermilab had aimed to reach 225 by August 25, but we postponed the accelerator shutdown until September 8, just in case we needed a little more time. As it turned out, the Beams Division achieved this milestone a few days early. That is a great achievement. Not only did we reach our goal, but getting there ahead of schedule will provide very valuable extra time to carry out work to prepare for the shutdown and to continue sending more collisions to the experiments. Congratulations to everyone who worked so hard to reach 225 inverse picobarns. It is a significant milestone for Run II, for our laboratory and for our users.

Accelerator Update
- Last week the Tevatron delivered 7.4 inverse picobarns. The total integrated luminosity for the last eleven months is more than 225 pb-1, exceeding the baseline performance goal for FY03.
- Six of the seven collider stores last week began with a peak luminosity higher than 40E30 cm-2sec-1.
- This week the Beams Division focuses on conducting accelerator studies.
- During this past seventy-two hour period, Operations established three stores. These stores delivered approximately sixty-one hours and twenty-eight minutes of luminosity to the experiments.
- A feeder 47 power glitch caused the Tevatron to quench.
