1. ATLAS Inner Detector online monitoring
During the commissioning of the ATLAS detector at CERN
important work is to ensure good quality of the data arriving from the
collisions. This project will work at combining data from the three
innermost tracker detectors. Frequent stays at CERN is needed in
particular participation during milestone weeks where all ATLAS
run as one. Data analysis of the Inner Detector data either from cosmic
radiation and/or from first data is will be part of this work.
2. ATLAS commissioning
The student will participate in the overall commissioning of
the Inner Detectors, the SemiConductor Tracker, which include detector
operation, programming for either the Detector Control System or the
Data Acquisition System or the Online data analysis system. Also
analysis of cosmic ray data will be needed. The student have the
opportunity to stay for a longer period at CERN possibly within the
technical students program *).
3. ATLAS data preparation
The student will contribute to the first analysis of the LHC
data from ATLAS, in particular the express stream, the 24 hour quick
readout of the data to determine the actuality of the data. This
includes analysis of Standard Model signals in the view of including it
in the express stream analysis. The student is expected to stay at CERN
during the test periods and data preparation periods.
4. ATLAS validation study of J/psi -> mu+ mu-, Upsilon(1S) -> mu+ mu-
using the first ATLAS data. A program will be provided
that produces an N-tuple with the necessary information. The task
is to generate Monte Carlo samples first and look at dependencies of
the efficiency versus transverse momentum, pseudo rapidity and azimuth
angle. The student should go to CERN during data taking.

6. Research of novel silicon photomultipliers for ILC
This work will include testing and calibration of a new
silicon photomultipliers, which will be a very good candidate for
linear accelerator experiments. The student will take part in testbeam
activity both in the USA and/or at CERN and data-analysis is
a central activity.
7. Research of 3D sensors for the ATLAS upgrade
Test and characterisation of 3D silicium-pixel detectors is
needed for higher luminosity detectors. Newly built sensors will arrive
in January which would need to be characterized. The student is
responsible of constructing and setting up a laser measurement system
and perform tests of these detectors with this system as part of the
characterisation. IV and CV curve measurements are also needed as well
as participation in testbeam activities at CERN and the corresponding
8. Construction and test of an electronic readout system for 3D detectors for the ATLAS upgrade
This work consists of setting up a readout system for the 3D
detectors based on the ATLAS pixel detector readout and to study the 3D
detectors with this readout. Also participation in testbeam activity at
CERN and corresponding data analysis will be needed.
9. Construction and development of a PET testbench
This project aim to bridge the gap between particle physics
and medical technology. The student will be setting up a small
testbench for medical imaging and to test this with both the
photomultipliers and the 3D sensors with various radioactive sources.
This work will be made in close collaboration with the PET center at
Haukeland University Hostpital.
10. Development of a cosmic radiation telescope
The radiation telescope is now in operation. The students work will
include improvement of the trigger through FPGA programming,
development of the DAQ system and study of efficiency.

Depending on background (courses) and interests, topics are available in the following areas:
T1. The main purpose of the LHC is to study the electroweak symmetry breaking: "why/how do particles get mass?"
Study of an extended Higgs sector, allowing for CP violation,
and investigating whether the Higgs sector could be related to the mysterious dark matter.
T2. Study properties of various dark-matter candidates,
(both within supersymmetric and non-supersymmetric models), and
whether they can be produced at the LHC.
