A £5
billion pounds "big bang"
'Big Bang' machine ready for launch
A view of the Large Hadron Collider in its
tunnel at a laboratory near Geneva
Scientists are to "switch on" the most
powerful pa
rticle accelerator ever built in an attempt to answer some of the
biggest unanswered questions in physics.
The £5 billion Large Hadron
Collider (LHC)
will smash protons - one of the building blocks of matter - into each
other at energies up to seven times greater than any achieved before.
In the flashes from the collisions,
scientists expect to reproduce conditions that existed during the first
billionth of a second after the Big Bang at the birth of the universe.
No-one knows precisely what will come
tumbling out of the primordial soup of disintegrating protons.
The LHC could help scientists explain mass,
gravity, mysterious "dark matter" and why the universe looks the way it
does.
It could also give them the first evidence of
extra spatial dimensions, and even create mini-black holes that blink
in and out of existence in a fraction of a second.
The LHC, a colossal machine housed in a 27
kilometre (17 mile) tunnel buried under 100 metres of rock, straddles
the borders of Switzerland and France between Lake Geneva and the Jura
mountains.
Beams of protons will be accelerated in
opposite directions through the ring-shaped tunnel, which is
supercooled to just 1.9 degrees above absolute zero (minus 271C), the
lowest temperature allowed by nature.
Concerns have been voiced - in particular
by German chemist Professor Otto Rossler - that black holes created by
the LHC will grow uncontrollably and "eat the planet from the inside".
But those involved in the project insist they
have reviewed all the evidence and concluded that it poses no risk to
the universe.

SPACE WEATHER WEEKEND AT ALABAMA A&MU
CISM is funded by the National Science Foundation. The scientific goal of CISM is to create models of the space environment, extending from the Sun to the Earth, that can be used for space weather prediction. CISM is headquartered at Boston University, but comprises a number of institutions including: Boston University, Alabama A&M University, University of California, Berkeley, University of Colorado, Boulder Dartmouth College , National Center for Atmospheric Research University of Texas at Arlington. University of Maryland, College Park. Rice University, SAIC and Stanford University
Kebede Research and Education Group
KREG stands for Kebede Space Science and Condensed Matter Physics Research and Education Groups. We specialize in curriculum design and practical research in space and material science. Based in the Physics Department, the space science program is very well equipped with state of the art facilities for astrophysical and space physics research. The material science program deals with cutting edge research in synthesis and characterization of materials that exhibit phenomenon such as superconductivity and magnetism. We are seeking qualified students and postdoctoral fellows to join these rewarding and challenging programs at NC A&T State University.

Talisha Haywood Master Thesis DEFENSE (Major Advisors: Abebe Kebede and Dhrananjay Kumar) . The work is supported by NSF-NIRT and NASA-MUCERPI2003STRUCTURAL AND FLUX-PINNING EFFECTS OF SELF-ASSEMBLED CeO2 NANODOTS ON YBa2Cu3O7-d THIN FILMS-For electrical power applications, high temperature superconductors such as YBa2Cu3O7-x (YBCO) need to possess a high critical current density (Jc); therefore it's critical to improve their current carrying capacity in high magnetic fields. Enhancement of Jc occurs by increasing the flux-pinning capability of the superconductor. The most promising approach to flux-pinning involves the introduction of homogeneous defects (such as nanodots) for pinning of moving vortices that cause current dissipation in high magnetic fields. In this work the study of the effect of CeO2 nanodots in the YBCO matrix is presented. This work is supported by NASA Capacity Building Partnership for Research and Education in Space Science, and The NSF NIRT program |

Recent Acquisitions
The
ITS30S is a new, 3-frequency version of the ITS10S and ITS20S receivers
originally developed in 1994 by NorthWest Research Associates. This
model was developed in anticipation of the three-frequency CERTO class
beacons, the first of which is scheduled to be launched in May of 2005.
Frequency coverage is approximately from -220 to +110 ppm, allowing
coverage of the NIMS (OSCAR) satellites on both Operational and
Maintenance frequencies, and the Geodetic and CERTO beacons operating
at +80 ppm. This range also covers two of the Russian NavSat
frequencies, 0 and -200 ppm The receiver is operated through an
associated Windows-based PC, and is intended to operate remotely and
unattended. The ITS30S is made to order, and so significant cost
savings can be realized if multiple units are ordered at the same time |

Space Technology curriculum proposedThe rapid growth of technology in our society has been sustained by the efforts of a technological team of professionals. The technologist is a key member of that team who is responsible for applying the research, analysis and design of his colleagues the scientist and the engineer. Technologists also supervise technicians who are involved in fabricating, operating, testing, troubleshooting and maintaining equipment and systems. Contact Drs. Abebe Kebede and Derreck Dunn to learn more about the space technology curriculum/ |
