For my Ph.D. thesis I am working on ATLAS and in particular on the SemiConductor tracker (SCT) project. SCT is a silicon based tracking detector that will cover a detection area of 60 m^2 at the center of the ATLAS experiment. I am currently working on tests of forward modules electrical and thermal performances and on analysis of test beam data. The SCT beamtest program consists of an extensive series of measurements to characterise the response of modules to beam particles, in particular considering Efficiency, Noise Occupancy and Spatial Resolution. I am performing analysis mostly for forward modules. SCT project is the hardware-dedicated part of my ph.D. thesis. I will join (beginning of 2003) the CDF experiment in order to perform physics analysis on real data.

I am working with the DELPHI detector at the LEP accelerator at CERN. My analysis searches for the neutral Higgs boson in the missing energy channel (where there is two neutrinos in the final state). I have previously analysed the data from 1998 and 1999 and are currently finishing the analysis of 2000 data.

My work is on the read-out electronics for the LHCb-RICH detectors. These Ring Imaging Cherenkov detectors are vital for particle identification in LHCb. I have mostly been concerned with the error correction/detection schemes for use between Level 0 (on detector) and Level 1 (off detector). There are various ways in which errors can occur, such as SEU's (Single Event Upsets) due to the high levels of radiation, or the loss of entire data words due to clock jitter etc. It is vital for the physics performance that such errors be detected, or corrected if at all possible. I will also be starting some analysis work in the next few months.

For my Ph.D. thesis I am working on CHORUS, an experiment with an hybrid setup that combines a nuclear emulsion target with various electronic detectors. This detector was exposed to the Wide Band Neutrino Beam from the CERN-SPS during the years 1994-1997. I am studing the quasi- elastic charm production induced by neutrinos. Selection criterias based on the kinematical reconstruction of the events have been studied and applied to the CHORUS statistics. Then I identified in the emulsions events with a quasi-elastic topology and a charm particle in the final state.The analysis of data will provide a measurement of the quasi-elastic charm cross-section with a better precision than previous experiments.

The major subject of my Ph.D. thesis is the measurement of the strength of the couplings between two W-bosons and a photon or Z-boson, the so-called Triple Gauge boson Couplings. This is a direct test of the non-abelian structure of the electroweak theory and any physics deviating from the Standard Model will give rise to anomalous values. I analyse the full high energy data of LEP using hadronic and semi-leptonic decay modes of W-pairs reconstructed with the L3 detector. During the last 2 years of LEP, I was based at CERN where I was also involved in the monitoring of the L3 luminosity detector.

During my Diploma thesis I work as a member of the SELEX collaboration (E781) on electromagnetic charge radius of pions. Beginning of 2000 I changed as Ph.D. student to the Universit‰t Karlsruhe and started a hardware related work. As a member of the CMS collaboration I focused on readout of CMS silicon tracker modules, of which we will micro-bond approximately 1600 in our home laboratory. For the quality and process control we developed test stations, allowing the measurement of a modules full characteristics.

For my Ph.D thesis i am working on the long base line neutrino oscillation experiment OPERA. The OPERA detector is composed of target with emulsion bricks, muons spectrometers and Target Trackers detectors. The target trackers is used to select the brick where the neutrino interaction took place and also to sample the energy of hadronic showers and to contribute to the identification of the penetrating tracks. I am performing simulation of photon production and propagation in the target tracker which is composed of scintillator strips and optical fibers. This study is very important because OPERA is a triggerless experiment and the event selection is based on software.

For my PhD thesis I am studying nuclear reactions by high energy proton (Ep=8.1GeV) and deuteron (Ed=7.3 GeV) beams on the separated isotopes as targets by activation method. Experiments were made at the Synchrophasotron of the JINR (Dubna, Russia). For deuteron-nuclear reactions we used thick-target, thick-catcher technique to study kinematic properties and angular distributions (in forward and backward) of product nuclei, give valuable information about the mechanism of their formation. We obtained information about the isospin dependence of reactionís cross-sections in the multifragmentation process. Now I am working on the experimental dataís treatment and analysis. The results of my works partially are published in 3 thesis of international conference.

I am engaged in measurement of the deuteron formfactors in elastic and inelastic electron scattering from the tenzor polarized deuterium gas target. These measurements are performed on the electron-positron storage ring VEPP-3 in Novosibirsk. My task was to perform polarization measurements of the target. Which includes development of the polarimeter, data acquisition, full detector simulation and finaly data analysis in elastic scattering. Now I am working on the analysis of the more complicated inelastic scattering in order to measure tenzor analyzing powers of the reaction. This includes development of the simulation based on Geant4 and analyzis tools using ROOT classes.
