Take a shower in the cosmos

Folks can now head on over to the Lederman Science Center to take a shower—of cosmic rays, that is.

A new exhibit at Lederman Science Center dramatizes the presence of cosmic rays, which continuously pelt Earth. The rays, made up of protons and the nuclei of heavier atoms, collide with other molecules in Earth’s atmosphere and split into decays of electrons, positrons and muons. These invisible decays, or showers, bathe the planet’s lower atmosphere.

“Hopefully, people who participate will realize that we’re immersed in cosmic rays all the time,” said Todd Johnson, AD.

The display demonstrates the showers with low-energy lasers. A motion detector senses when a person steps into the phone-booth sized shower and lasers paint the individual in momentary lines of fluorescent color. A cartoon-laser sound of “pew-pew-pew” accompanies the traces.

Six scintillator panels housed in a clear panel over hanging the shower detect cosmic rays in real time.

Special Announcement

Be alert during concrete work

Temporary safety canopies will protect people passing through the entrances at Wilson Hall.

Starting this week, the Wilson Hall exterior concrete inspection and cleaning project will commence work on both north and south facades of Wilson Hall and the front entry plaza. Building personnel and visitors will be guided through temporary safety canopies at all main entrances to Wilson Hall. Work is expected to be completed by Nov. 1, depending on the weather.

Please direct any questions to the Wilson Hall Building Manager John Kent.

Antimatter surplus is not dark matter's smoking gun

From New Scientist, Sept. 6, 2011

Antimatter enthusiasts will love it; dark matter hunters not so much. NASA's FERMI satellite has confirmed a previous hint that there is more antimatter than expected coming from space. The bad news is that the result almost certainly rules out dark matter as the source.

The results were reported online by the FERMI Large Area Telescope Collaboration. They hit the web just in time for the Topics in Astroparticle and Underground Physics conference taking place in Munich, Germany, this week, where they were immediately incorporated into the first talks.

As far as antimatter is concerned, the results back up intriguing signals picked up in 2008 by the Russian-European PAMELA satellite. The result showed that there were more positrons – the antimatter counterpart of electrons.

From the Technical Division

Giving back to the community

Giorgio Apollinari

Giorgio Apollinari, head of the Technical Division, wrote this week’s column.

Our director has made clear several times that the future of our laboratory hinges on the consensus we can build and obtain within the worldwide high-energy physics community. This is because no laboratory (or any other societal form, for that matter) is an island in itself.

Today I wish to report about interactions we have established with science communities beyond our HEP world, communities for which the technology know-how developed at Fermilab represents a huge asset to achieve ambitious scientific goals.

First and foremost, Fermilab is interacting with the worldwide fusion energy community on the construction of ITER, a demonstration reactor in Cadarache, France. The US is involved through a US-ITER collaboration, which contributes to the project through the construction of Niobium Tin (Nb3Sn) magnets. The work done at Fermilab for the LHC Accelerator Research Program includes magnets that achieve fields of 11 Tesla. This work makes for a well-established technology springboard. We began working with US-ITER on the design and cryogenic integration of the Central Solenoid, the electromagnet at the center of ITER’s fusion device that allows the device to achieve the highest current of stored magnetic energy possible. We hope to contribute to the testing of these important ITER elements in the US, possibly at Fermilab.

Safety Update

ES&H weekly report, Sept. 6

This week's safety report, compiled by the Fermilab ES&H section, includes four incidents. One was recordable. An employee was stung by an insect, but did not require first-aid treatment. Another employee suffered a contusion on his abdomen when he was struck by the handle of a cart, and he received first-aid treatment. A third employee required first-aid treatment after he experienced back pain while lifting. A fourth employee had a foreign object in his eye that required medical treatment and prescription drugs, making the incident recordable.
