|Muons Inc. Will Co-Host
Muon Collider Workshop
| Retired Fermilab physicist Rol Johnson and the company he founded in 2002, Muons Inc., are using Small Business Innovation Research (SBIR) grants for
basic research on future accelerators. Now, along with Fermilab's Technical Division, Muons Inc. will co-host the Low Emittance Muon Collider Workshop, to be held at the lab from February 6 to 10, 2006. "Our first projects were to invent ways to cool or shrink beams of muons almost as much as antiprotons are cooled for the Tevatron collider. Now we want to use these new inventions to design a muon collider based on this extreme muon cooling, where muons are accelerated to high energy by recirculating through ILC RF cavities," says Johnson.
Despite problems associated with cooling beams of particles that only live 2.2 microseconds, the potential payoff of higher-than-ever energy collisions continues to motivate Johnson. Calculations indicate
a muon collider with the same circumference as the Tevatron could provide higher constituent center of mass energy and luminosity than anything else now planned. "Our design goal is 5 TeV with an average luminosity of 1035. The extreme muon cooling that we are developing leads to high luminosity with smaller beams and fewer muons than were previously thought possible," says Johnson.
Johnson and colleagues are still in the research stage, but he says, "We think we've got all the pieces and we now have to put them together to get a believable design for a muon collider and a neutrino factory." The Low Emittance Muon Collider Workshop may help to put it all together. More information can be found at the workshop website.
|Doug Michael, co-spokesperson for MINOS, passed away over the winter holiday. Fermilab Today will honor his contributions to the lab with an obituary in the near future.

Thriving under our noses, stealthily: coyotes
Scientists have long thought coyotes intently avoid cities, but a new study has found the opposite.
Groups of the historically maligned dog relatives are thriving in some large U.S. cities: they lurk in darkness and come out at night, probably helping the human inhabitants by eating vermin, the study found.
This animalís amazing ability to thrive in cities has surprised scientists, said Stanley Gehrt of Ohio State University, who is studying coyotes in urban Chicago.
Since the study began six years ago, Gehrt and his colleagues say they have found that urban coyote populations are much larger than expected; that they live longer than their rural cousins in these environments; and that they are more active at night than coyotes living in rural areas.
Coyotes also do some good: they help control rapidly growing populations of Canada geese throughout North America, Gehrt said. And while his coyote research is concentrated in Chicago, he said, the results likely apply to most major metropolitan areas in North America.
Arc Flash: Hidden Danger
Electrical safety precautions generally focus on the harmful effects of direct contact with energized components. This makes sense because relatively little electrical power is needed to initiate a startle response, upset heart rhythm, "freeze" muscle movements or burn tissues; these are the electrical hazards that most people can expect to encounter in their day-to-day lives. However, there is another kind of electrical hazard called "arc flash" that does not require direct contact to cause serious injury, but can only occur in high power circuits.
Do not work on energized parts, either diagnostic or manipulative, unless special precautions, training and appropriate permits have been completed.
An arc flash involves the flow of current through the air between conductors. Since the arc is extremely hot, a number of bad things happen very quickly. The arc radiates intense thermal energy resulting in potential skin/eye burns and fires. The sudden increase in temperature melts metals adjacent to the arc and produces a pulse of pressure. Loose objects, including molten metal droplets, as well as nearby people, can be propelled away from the arc. The pressure pulse also produces a loud noise that can damage hearing.
FESHM chapters 5042 and 5040 have been revised to incorporate the arc flash precautions contained in a recent update to NFPA 70E, "Electrical Safety in the Workplace". The most important point to remember is that at Fermilab, we do not work on energized parts, either diagnostic or manipulative, unless special precautions, training and appropriate permits have been completed. In addition, you should stay away from electrical equipment that is being worked on and respect all barriers, signs and the directions given by the electrical worker or safety observer.

Summer Housing Requests
The Fermilab Housing Office is now taking requests for houses, apartments,
and dormitory rooms for the summer of 2006. Since there will be a large influx
of experimenters, and requests are anticipated to be in excess of our available
facilities, you are urged to submit your request for reservations to the
Housing Office by Wednesday, March 1, 2006. Requests can be made for
any period and need not commence on any particular date. For further information, please
call (630) 840-3777 or
Individual housing requests can be made by using our Online Housing Request
(Requests for multiple housing units are best handled by direct email.)
