NUMI Project Offers Extra Tours for Employees and Users Advance Registration Required | ||
| ||
|
Due to the popularity of the recent tours of the NUMI tunnel and the
MINOS near detector hall, the NUMI project will offer additional tours to employees
and users starting Tuesday, October 12. The additional tours will be available
every Tuesday afternoon at 2:30 p.m. and 3:30 p.m. until the end of October. Ten
people will be allowed to sign up for each tour. A bus will pick up the tour groups in front of Wilson Hall and bring everyone back at the end of the tour. Employees and users must register in advance. The NUMI project recommends that interested employees and users sign up right away for these extra Tuesday tours because the Wednesday tours filled up within minutes of being announced.
Each tour lasts for about an hour and a half and consists of a vigorous underground hike. An elevator ride will take the group down 140 feet at the MI-65 entry point, where employees and users can view the beamline that delivers protons to the two magnetic 'horns', whose peak power reaches 40 MegaWatts. The next part of the tour consists of a long walk down the decay tunnel, which is very damp and somewhat dark and cramped. Rock strata and newly formed stalactites will be visible at various locations. The tour ends up 360 feet underground in the MINOS near detector hall, where 980 tons of steel and scintillator are waiting to observe their first neutrino interactions. This tour is not for everybody, especially if you are claustrophobic, physically infirm or don't like to get wet. Parts of the tour involve stairs and walking down a slope, which will be similar to walking on a wet hiking trail. A dress code of hiking boots or sneakers and long pants is mandatory. Tank-tops and sleeveless shirts are not allowed. Employees and users who are not properly dressed will not be allowed to join the tour. A light coat is also recommended. Hard hats, eye protection and personal rescuers will be provided for each person.
Employees and users who would like to sign up for a tour should contact Nancy
Lanning at edreg@fnal.gov or x5588. Please indicate which tour you would like to sign up for and provide contact information. The deadline to sign up for the October 12 tour is noon on October 11.

DOE Funding Helps Fermilab and the Environment | ||
| ||
|
The DOE Federal Energy Management Program (FEMP) has been helping to fund energy
efficiency projects at Fermilab that were conceived under the lab's former
Utility Incentive Program (UIP). "Working with Victor Petrolati of FEMP's
Departmental Utilities Energy Team (DUET), Fermilab has received over $1.2
million dollars over the past few years to implement these energy savings
projects," said Steve Krstulovich of FESS.
Even in this period of lean budgets,
this year Fermilab has been awarded $330K for three more projects. These
include the A-0 Wing Lighting Retrofit, and the Sitewide Lighting Retrofit
Phase 2 & 3 projects. The projects completed in the last three years have
earned the lab several Federal Energy and Water Management Awards while
helping reduce operating costs by about $350K annually. Most recently
the lab was notified of an FY04 award for the Condensation Control on the
Rings Project, which added dehumidifiers in the TeV enclosure. In total,
the FEMP funded projects avoid the use of over 8,500 MWh of electricity and
nearly 6 Million cubic feet of natural gas annually, which in turn preclude
nearly 1,500 metric tons of carbon emissions to help improve the environment.

From FYI: AIP Bulletin of Science Policy News, October 6, 2004 Presidential Candidates on Science Issues While science and technology issues have not been raised in the presidential and vice-presidential debates thus far, there are a number of web sites featuring the positions of President George Bush and Senator John Kerry on science policy. These include articles in two magazines published by the American Institute of Physics, in Science, Science Express, and Nature. Last week, the American Association for the Advancement of Science held a well-attended candidates' forum at which spokesmen for President Bush and Senator Kerry presented the two candidates' views on science policy and funding questions. An audio archive is available of this forum. Read more |

CDF discovers the Charm of Charmless Beauty | ||
| ||
|
The Bd and Bs decay modes into two light (charmless)
mesons (B->h+h-) offer unique opportunities to study the
elusive effects of CP violation and their relationship with
the fundamental weak phases of the CKM matrix.
Unfortunately, they are not easy to observe: the signal to
background ratio is on the order of Nevertheless, a clean signal of about one thousand such decays has been reconstructed by a CDF team from Pisa, Padova, Roma and Trieste universities, using 180 pb-1 of data collected by triggering on displaced vertices. The signal peak is actually a superposition of several closely spaced signals, Bd->pipi, Bd->Kpi, Bs->KK and Bs->Kpi being the largest contributors. The Bs->KK mode had never previously been observed. CDF measured its branching fraction to be 34.3+-5.5(stat)+-5.9(syst)x10-6, thus confirming recent predictions based on QCD factorization. With more data, lifetime and time-dependent CP asymmetries will be measured, which when combined with Bd->pipi asymmetries will constrain the angle gamma of the CKM matrix, a fundamental parameter on which little experimental information is available. The Bd->Kpi mode, a first at a hadron collider, is the only B decay where "direct" CP violation has been demonstrated. CDF's measurement of the asymmetry is -0.04+-0.08(stat.)+-0.01(syst.). CDF expects from data on tape a Bd->Kpi sample of same size as current B-factories samples, plus a measurement of the asymmetry in the Bs->Kpi mode, inaccessible to other experiments. | ||
