A Word from the head of
department
While writing this, I am
sitting at TU Delft at the start of a conference on European Platform of
Universities Engaged in Energy Research, Education and Training. There have been
several interesting lectures where one consistent and rather important element
has been how to coordinate research, education and innovation within energy which takes place across disciplines and institutions.
It is easy to recognize the challenges we have at our faculty when it comes
to both interdisciplinarity and cooperation with the
border zone and industry to mutual benefits. The lectures from this conference
will be uploaded on their webpagge for those who want to read more. Have a great
weekend! News and general information
Update on Neutrino Time of Flight
measurement
The OPERA collaboration has informed
its funding agencies and host laboratories that it has identified two
possible effects that could have an influence on its neutrino timing
measurement. These both require further tests with a short
pulsed beam. If confirmed, one would increase the
size of the measured effect, the other would
diminish it. The first possible effect concerns an oscillator used to
provide the time stamps for GPS synchronizations. It could have led to an
overestimate of the neutrino's time of flight. The second concerns the
optical fibre connector that brings the external
GPS signal to the OPERA master clock, which may not have been functioning
correctly when the measurements were taken. If this is the case, it could
have led to an underestimate of the time of flight of the neutrinos. The
potential extent of these two effects is being studied by the OPERA
collaboration. New measurements with short pulsed
beams are scheduled for May. Workshop Bergen COMSOL User Group
Bergen COMSOL User Group
organizes a half day workshop (from 12-15) on COMSOL
Multiphysics at CMR/ Fantoft
Wednesday March 7th. More information can be found here. Everyone interested in
(or using) COMSOL Multiphysics is invited. If you are interested in
any specific topics, please send an email to jan@cmr.no. STUDENTs
The Norwegian Physics
Students’ Conference 2012
In short,
NoFFo is an association of various physics students organizations from UoB,
NTNU and UoO. In addition, UMB from Ås, and Fysikkforeninga from UoT are also interested in joining. Noffo
is also a sub-association of the International Association of Physics
Students which arranges annually the International Conference for Physics Students. NoFFo
elects at its general gathering the Norwegian representatives to participate
in the international conference. The main activity of NoFFo is
arranging the annual Norwegian Physics Students’ Conference. It is a rather
big conference which takes place over one weekend, and which is usually held
either in Bergen, Trondheim or Oslo. Last year we had our conference at UoB, and this year it is UoO’s
turn. NFK is a scientific and social event where the main aim is to get to
know the people outside the university limits – and this is our only
opportunity to build networks of this type. Usually there is a series of
lectures on physics and related topics divided between Saturday and
Sunday. In the evenings there is an arranged dinner, followed by a party and
general socializing, and that is in fact the main point of this conference. There
will also be time for some tourist activities, since one is already visiting
a different town. In addition, NoFFo organizes
its general gathering on Friday, where they elect the president for the next
term. We are a
bit late this year and the registration should take place as soon as possible
at NoFFos webpage – get into action – this can
really be a lot of fun! We are trying to get most of the travel costs covered,
or as much of it as we can, but it also partly depends on how many people
need to travel to the location – and conference participation is free
of charge. To find out which type of transport will be arranged, we also need
to know the approximate number of those travelling. It would therefore be
great that all of you intending to travel give us a feedback on it as soon as
possible. The Physics Society here in Oslo usually lends us one of their
buses in order to travel to Trondheim or Bergen when the conference is held
there. In case of any questions or feedback, please contact Jonas van den Brink at UoO or the leader Hulda S. Fadnes who is the head of Committee for
Physics and Technology. She informs us that the department’s PTEK-students are
also very welcome at the conference. Publications registered in ISI Web of Science
