| The Fermilab Today guide to the Channel 13 monitor |

On channel 13, the Tevatron and its high-energy physics buddies are the celebrities. Displaying a computer program called "Notify," TV monitors across Fermilab show important information about experiments around the lab. But without clear explanation, the numbers on the screen can be confusing.
To help boil down the information, Fermilab Today interviewed Wally Kissel of the Accelerator Division. The numbers below correspond with numbered areas in the screen shot above.
1 - The line of numbers represents a "supercycle"--a rapid sequence of commands sent as a series of numbers to accelerator hardware. When a device hears its number, it begins a function such as antiproton stacking or sending particle beam to various experiments. 2 - The number of particle stores since the Tevatron began its second run is displayed as "Store." Below, "B0Lum" and "D0Lum" show the luminosities of CDF and D0 detectors, respectively - the bigger, the better. "SDur" shows how long particles were last stored in the Tevatron and "MT" shows how many particles per pulse are sent to the Meson Test area. 3 - When particle beams circulate in the Tevatron, "TevKE" shows how much energy each beam would have in billions of electron volts. The next three figures give particle counts for the Tevatron - "TevDC" displays the total number, "TevPR" gives the proton count and "TevPB" shows the antiproton count. "MC," similar to "MT," shows how many particles per pulse are delivered to Meson Center. 4 - The third column deals mostly with antiprotons, also known as pbars. "Stack" shows how many are in the accumulator ring while "AccRT" and "ProdEff" respectively show the stacking rate and production efficiency of pbars. "MB" shows the rate of protons delivered from the Booster to the MiniBooNE project and "Npwr" shows the power rate of particles sent to NuMI. 5 - Beneath the current date and time, "MI" shows the intensity of the particle beam coursing through the Main Injector. "RR" below it displays the number of pbars stored in the Recycler Ring while "NuMI" shows the number of particles sent to the NuMI experiment. The most popular item on Channel 13, Kissel says, is the outside temperature shown as "Temp" in this column. 6 - This area shows automated messages about lab activity. 7 - In this space, human-created messages summarize major activities currently underway. A graph of the Main Injector's bending magnet current is shown in red while the MI proton beam current is displayed in green.

A team of US scientists, including a group from the Stanford Linear Accelerator Center, reported direct evidence of dark matter Monday. You can watch television coverage from a California news station here.

Science,
August 21, 2006:
Dark Matter Exposed? A smoking bullet clinches the case for dark matter in galactic clusters, NASA announced today. The cluster of galaxies designated 1E0657-56, known as the "bullet cluster" for its picturesque bullet-shaped cloud of superhot gas, has provided astronomers with the best evidence yet that intergalactic space is filled with the same stuff that provides the gravity needed to hold the galaxies together.

| This week's column features Marc Ross, the new head of the Technical Division.
It was with pleasure that recently I accepted Director Pier Oddone's offer to
Though most of my career has been at SLAC, like many of my HEP colleagues I spent younger days here. As an undergraduate student, when the lab was new, I worked in the Meson Lab for a few years with the Northwestern University group under the expert guidance of Professor Bruno Gobbi. More recently, I came to the lab along with several SLAC colleagues to help with the operation of the Tevatron and Recycler. It is widely recognized that High Energy Physics accelerator builders must come together to develop our future. That future includes the International Linear Collider. Independent of the ultimate placement of this machine, Fermilab will have an important place in the collaboration developing the ILC. I hope that, with the help of the Technical Division, and all of Fermilab, I can help to make this happen, and in fact make a small part of history repeat itself. First, that by again growing collaborative efforts between Fermilab and others, I can help create a technically excellent machine--just as creating the Tevatron offered technical excellence to an earlier generation. Then, after this new effort in accelerator-building, Fermilab will remain the place for young students to come and explore, and build the future. |
