SppC based energy frontier lepton-proton colliders: luminosity and physics

In this study, main parameters of Super proton-proton Collider (SppC) based lepton-proton colliders are estimated. For electron beam parameters, highest energy International Linear Collider (ILC) and Plasma Wake Field Accelerator-Linear Collider (PWFA-LC) options are taken into account. For muon beams, 1.5 TeV and 3 TeV center of mass energy Muon Collider parameters are used. In addition, ultimate $\mu$p collider which assumes construction of additional 50 TeV muon ring in the SppC tunnel is considered as well. It is shown that $L_{ep}$ $\sim$ $10^{32}$ $cm^{-2}s^{-1}$ can be achieved with moderate upgrade of the SppC proton beam parameters. Physics search potential of proposed lepton-proton colliders is illustrated by considering small Bjorken x region as an example of SM physics and resonant production of color octet leptons as an example of BSM physics.Comment: 11 pages, 3 figures, 8 table

TECHNICAL DESIGN STUDIES OF TAC SASE FEL PROPOSAL*

Abstract A SASE FEL facility was first proposed in Feasibility Report of the TAC (Turkish Accelerator Center) project in 2000. Conceptual Design Report (CDR) of the project was completed in 2005. Technical Design Report (TDR) studies of TAC were started in 2006 in frame of an inter universities project with support of State Planning Organization (SPO) of Turkey. Main goal of the SASE FEL proposal is to cover VUV and soft X-rays region of the spectrum besides IR-FEL, Bremsstrahlung and Synchrotron Radiation proposals of TAC. Up to now, optimization studies based on a special RF linac or an Energy Recovery Linac (ERL) for the SASE FEL facility, were completed. Today, ERLs provide a powerful broad range of applications like: electron cooling devices, high average brightness, high power FELs, short-pulse radiation sources and high luminosity colliders. In this study, main parameters for two linac options and SASE FEL are given. OVERVIEW OF THE TAC SASE FEL FACILITY PROPOSAL It was first planned that, TAC linac-ring type collider's 1 GeV electron linac should asynchronously be used as a driver for SASE FEL facility [1], as shown i

Luminosity and Physics Considerations on HL-LHC and HE-LHC based mu-p Colliders

Construction of future Muon Collider tangential to the Large Hadron Collider will give opportunity to realize mu-p collisions at multi-TeV center of mass energies. Using nominal parameters of high luminosity and high energy upgrades of the LHC, as well as design parameters of muon colliders, it is shown that L_mu-p of order of 10^33 cm^-2s^-1 is achievable for different options with sqrt(s)_mu-p from 4.58 TeV to 12.7 TeV. Certainly, proposed mu-p colliders have a huge potential for clarifying QCD basics and searches for new physics

Composition of the essential oils of subspecies of scutellaria albida L. from Turkey

The essential oil obtained by hydrodistillation from subspecies of Scutellaria albida L. (Lamiaceae): S. albida L. subsp. albida, S. albida L. subsp. colchica (Rech.f.) J.R.Edm., S. albida L. subsp. condensata (Rech.f.) J.R.Edm., and S. albida L. subsp. velenovskyi (Rech.f.) Greuter et Burdet from Turkey were analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS), simultaneously. Linalool (20% and 29%) was identified as major component in the oils of S. albida subsp. albida and S. albida subsp. condensata oil, respectively. In the oil of S. albida subsp. colchica, hexadecanoic acid (13%) was found as major component. β-Caryophyllene (20%) was the main component of the oil of S. albida subsp. velenovskyi. © 2010, Taylor & Francis Group, LLC.

The electron linac will consist of two sequenced modules, each housing two 9-cell superconducting TESLA cavities for cw operation. It is planned that the TAC IR FEL facility will be completed in 2012 at Gölbasi campus of Ankara University. This facility will give an opportunity to the scientists and industry to use FEL in research and development in Turkey and our region.

X-ray Raman spectroscopy of lithium-ion battery electrolyte solutions in a flow cell.

The effects of varying LiPF6 salt concentration and the presence of lithium bis(oxalate)borate additive on the electronic structure of commonly used lithium-ion battery electrolyte solvents (ethylene carbonate-dimethyl carbonate and propylene carbonate) have been investigated. X-ray Raman scattering spectroscopy (a non-resonant inelastic X-ray scattering method) was utilized together with a closed-circle flow cell. Carbon and oxygen K-edges provide characteristic information on the electronic structure of the electrolyte solutions, which are sensitive to local chemistry. Higher Li+ ion concentration in the solvent manifests itself as a blue-shift of both the pi* feature in the carbon edge and the carbonyl pi* feature in the oxygen edge. While these oxygen K-edge results agree with previous soft X-ray absorption studies on LiBF4 salt concentration in propylene carbonate, carbon K-edge spectra reveal a shift in energy, which can be explained with differing ionic conductivities of the electrolyte solutions
