A
Word from the Head of Department
Heavy collisions at CERN – a great
milestone is reached
Joakim
Nystrand is reporting that, after approximately 20 years of preparations and
waiting, and almost a year after the first proton-proton collisions; lead
nuclei (Pb+Pb) were successfully collided in the LHC (Large Hadron Collider) at
CERN for the first time!
This means
an increase of energy in the center of mass with more than one order of
magnitude compared to the earlier record at RHIC at Brookhaven National
Laboratory. The first collisions took place Sunday morning without the
declaration of "Stable Beams". This, however, happened on Monday
morning (November 8) and thereby it is safe to record the high voltage on all
detectors in the ALICE (A Large Ion Collider Experiment) experiment and take
data with the entire experiment. The first central collisions in which the
entire detector is filled with tracks, were registered online in the course of
a few minutes, see the above figure. So far ALICE has collected more than 5
million Pb+Pb collisions and the analyses of these are being carried out. Visit
ALICE-page for more information and more pictures like the one
above. In addition, CMS and ATLAS experiments are also participating in the
data collection from the heavy ion run.
The Subatomic
physics group in Bergen has been involved in the ALICE experiments since the
beginning, and here, the focus is exactly on studying collisions between heavy
nuclei. We would like to congratulate the Subatomic physics group with this
milestone!
News
and General Information
YearÕs mini winter-school
at CERN
Heidi Sandaker
has sent us pictures from this yearÕs mini winter-school at CERN. Students involved in the
PHYS115 course were also present at the school that we arrange together with
students from the University of Oslo every year (see the picture below). This time there were 18 participants from Bergen. This year, as in the
previous years, there were many especially good lecturers, including Lyn Evans
(project leader for the construction of LHC), Peter Jenni (spokesman for the
ATLAS experiment for over 15 years), and the theoreticians Gian Giudice and
John Ellis (see the picture below – with Korean TV-team). Also a visit
and a tour of the ALICE experiments and the IT-department were arranged.

Last reminder: applications to Meltzerfondet (Meltzer Funds) and Bergen
Universitetsfond (Bergen University Funds)
The application deadline for these
funds is just around the corner: December 1.
Meltzerfondet: Project and travel funds for researchers. Funds
for scientific projects which are approved by the advisor and connected to
studies or PhD positions.
Bergen
Universitetsfond: Researchers can apply for funding of
dissemination of projects and publication of research results, as well as
funding for holding scientific conferences, workshops.
Application for parking permit in Dokkeveien
It is now
possible to apply for parking permits in UoBÕs parking lot in Dokkeveien.
Budget 2010
We would
like to recall what was said before; it is not a matter of course to transfer
assets from the 2010 budget to the budget of 2011.
