The OPERA experiment is designed to perform first direct observation of $\nu_{\tau}$ appearance in an almost pure $\nu_{\mu}$ beam. The OPERA detector is a hybrid set-up which combines a lead/emulsion target with various electronic detectors. It is located in Gran Sasso Laboratory (LNGS), 730 km away from CERN where neutrino beam is produced. A good electron identification in the ECC brick would also allow OPERA to search for $\nu_{\mu}\rightarrow\nu_{e}$ oscillations. We have studied electron identification in the Emulsion Cloud Chamber (ECC) brick which was exposed to CERN SPS H4 electron beam. Emulsion scanning was performed in LNGS scanning laboratory. FEDRA framework was used for the data analysis. In total, we have found 30 electron showers in the brick. The characteristics of each shower have been studied. The background base-track contamination in the shower was estimated as $20\pm 4$. This is mainly due to shower overlap of electrons and passing through cosmic rays.

High speed automatic scanning systems for emulsion analysis in the opera experiment Altınok, Özgür; Güler, Ali Murat; Department of Physics (2011) The aim of the OPERA experiment is to verify the neutrino oscillation, directly measuring the appearance of from an initially pure beam produced at CERN. For this purpose OPERA detector is located underground Gran Sasso Laboratory(LNGS) 730 km away from CERN. The detector structure designed to be a hybrid system consisting of emulsion targets and electronic detectors. Total area of the emulsion targets in the OPERA detector is around 110000 m2 which needs fast and reliable automatic scanning systems. For th...
Measurement of (anti-) neutrino-nucleon structure functions in chorus experiment Kama, Sami; Serin, Meltem; Department of Physics (2005) In this work an analysis of the CHORUS (anti-)neutrino-nucleon scattering data taken on lead--scintillator calorimeter during the 1998 run is presented. The differential cross-sections are measured in the range of Þ0.01
Study of charged hadron multiplicities in charged-current neutrino-lead interactions in the OPERA detector Agafonova, N.; et. al. (Springer Science and Business Media LLC, 2018-01-24) The OPERA experiment was designed to search for nu(mu) -> nu(tau) oscillations in appearance mode through the direct observation of tau neutrinos in the CNGS neutrino beam. In this paper, we report a study of the multiplicity of charged particles produced in charged-current neutrino interactions in lead. We present charged hadron average multiplicities, their dispersion and investigate the KNO scaling in different kinematical regions. The results are presented in detail in the form of tables that can be use...
Do background to neutrino oscillations in the opera experiment Tufanlı, Serhan; Güler, Ali Murat; Department of Physics (2009) The OPERA experiment is designed to search for nu-tau appearance in almost pure CERN-SPS nu-mu beam. The OPERA detector is placed in the Gran Sasso underground laboratory which is 730 km away from CERN. It is a hybrid set-up which combines a lead/emulsion target with various electronic detectors. The detector is composed of two super modules(SM) which contains about 150,000 ECC bricks. Each of the brick is obtained by stacking 56 lead plates with 57 emulsion films. Behind the each brick, an emulsion film do...
Procedure for short-lived particle detection in the OPERA experiment and its application to charm decays Agafonova, N.; et. al. (2014-08-01) The OPERA experiment, designed to perform the first observation of nu(mu) -> nu(tau) oscillations in appearance mode through the detection of the tau leptons produced in nu(tau) charged current interactions, has collected data from 2008 to 2012. In the present paper, the procedure developed to detect tau particle decays, occurring over distances of the order of 1 mm from the neutrino interaction point, is described in detail and applied to the search for charmed hadrons, showing similar decay topologies as ...
