Brief Overview of Turkish Parscipason in CERN Experiments Brief overview of Turkish par1cipaon in CERN experiments Mehmet Zeyrek METU KTO Karatay University Konya, 29 Nov. 2013 1 History • Mainly theore1cal HEP studies dominates aer the first groups formed by E. İnönü, F. Gürsey, A. O. Barut and others… Main theore1cal centers has been in Ankara Univ, Bogazici Univ, METU • Experimental HEP studies and CERN collaboraons started at METU aer the second half of 1960s (ini1ated by Prof. Tolun) 2 Prof. Perihan Tolun 1934-2013 3 ! Perihan Tolun 1934–2013 Perihan Tolun, the first experimental particle physicist of Turkey and Middle East Technical University (METU), passed away on 27 May in Istanbul at the age of 79. Perihan Tolun graduated in the top rank from the science branch of Arnavutköy American College for Girls, a renowned high school in Istanbul, in 1955. She then came first among the physics applicants for a Rockefeller scholarship to study abroad for an advanced degree. She used the scholarship to go to Bristol University, where she earned her BSc in 1961 and a PhD in 1966 . While in Bristol, she worked in Cecil Powell’s group, participating in experiments at the Proton Synchrotron, which is how her association with CERN began. Following invitations from the eminent Turkish physicists Erdal İnönü and Feza Gürsey, Tolun joined the Physics Department at METU, Ankara, in 1966. She spent the rest of her career there until her retirement in 2001, with periods as a research associate at Yale University (1970–1971) and CERN (1976–1977). She remained an active researcher at METU until the beginning of 2013, just before her illness was diagnosed. At METU, Tolun started the first group in experimental particle physics and set up a laboratory where manual stereo microscopes were installed for analysis of elementary-particle tracks in plates of photographic emulsion. The lab was then equipped with an automatic microscope system, in which a CCD camera reads out the image for the CHORUS experiment. A new system was later developed for the OPERA experiment in the Gran Sasso National Laboratory. Tolun’s first experiment at CERN, with Powell’s group for her PhD, involved the measurement of the magnetic moments of the Λ0 and Σ+ hyperons. After she joined METU in 1966, under her leadership the group from Ankara collaborated with CERN, Lausanne, Munich and Rome in the subsequent experiment, making precision measurements of the magnetic moment of the Λ0 hyperon. In 1977, her group joined the WA17 experiment, measuring the lifetime of charmed hadrons produced in neutrino interactions. From 1991 onwards, her participation in the CERN neutrino programme continued with the CHARM II and CHORUS experiments, with significant Turkish contribution, especially in CHORUS. Following her lead, after the CHORUS experiment, METU joined the OPERA collaboration. Tolun was highly respected: she was compassionate, courteous, thoughtful and candid. She dedicated her life to science and her passing away is a great loss to the particle-physics community in Turkey. She will be remembered by her students and colleagues as a brilliant researcher, inspiring teacher and advisor. • Mehmet Zeyrek, METU/Ankara.

    CERN-PH-TH/2006-175 September 2006 Physics Opportunities with Future Proton Accelerators at CERN A. Blondel a, L. Camilleri b, A. Ceccucci b, J. Ellis b , M. Lindroos b , M. Mangano b , G. Rolandi b a University of Geneva CH-1211 Geneva 4, SWITZERLAND b CERN, CH-1211 Geneva 23, SWITZERLAND Abstract We analyze the physics opportunities that would be made possible by upgrades of CERN’s proton accelerator complex. These include the new physics possible with luminosity or energy upgrades of the LHC, options for a possible future neutrino complex at CERN, and opportunities in other physics including rare kaon decays, other fixed-target experiments, nuclear physics and antiproton physics, among other possibilities. We stress the importance of inputs from initial LHC running and planned neutrino experiments, and summarize the principal detector R&D issues. 1 Introduction and summary In our previous report [1], we presented an initial survey of the physics opportunities that could be provided by possible developments and upgrades of the present CERN Proton Accelerator Complex [2,3]. These topics have subsequently been discussed by the CERN Council Strategy Group [4]. In this report, we amplify and update some physics points from our initial report and identify detector R&D priorities for the preferred experimental programme from 2010 onwards. We consider experimentation at the high-energy frontier to be the top priority in choosing a strategy for upgrading CERN's proton accelerator complex. This experimentation includes the upgrade to optimize the useful LHC luminosity integrated over the lifetime of the accelerator, through both a consolidation of the LHC injector chain and a possible luminosity upgrade project we term the SLHC.

  • 2.15 CTF3 Status, Progress and Plans
    165 2.15 CTF3 Status, Progress and Plans R. Corsini, P. Skowroński, F. Tecker, CERN, CH-1211 Geneva 23, Switzerland Mail to: [email protected] 2.15.1 Introduction The aim of the CLIC Test Facility CTF3 (see Fig. 1.1), built at CERN by the CLIC International Collaboration, is to prove the main feasibility issues of the two-beam acceleration technology [1]. CTF3 consists of a 150 MeV electron linac followed by a 42 m long Delay Loop and a 84 m Combiner Ring. The beam current from the linac is first doubled in the delay loop and then multiplied again by a factor of four in the combiner ring by interleaving bunches using transverse RF deflecting cavities. The high current beam can then be sent in the CLIC experimental area (CLEX) where it can be decelerated to extract 12 GHz RF power to be used for high gradient acceleration. In the same area a 200 MeV injector (CALIFES) generates a Probe Beam for two-beam experiments. Figure 1.1: CTF3 overall layout. CTF3 was built in order to demonstrate the following two main issues [2]: 1. Drive Beam Generation: efficient generation of a high-current electron beam with the time structure needed to generate 12 GHz RF power. CLIC relies on a novel scheme of fully loaded acceleration in normal conducting travelling wave structures, followed by beam current and bunch frequency multiplication by funneling techniques in a series of delay lines and rings, using injection by RF deflectors. CTF3 is meant to use such a technique to produce a 30 A Drive Beam with 12 GHz bunch repetition frequency.
