Preliminary Modeling Of Radiation Levels At The Fermilab PIP-II Linac / Lari, L. (Fermilab ; CERN) ; Cerutti, F. ; Esposito, L.S. ; Baffes, C. ; Dixon, S.J. ; Mokhov, N.V. ; Rakhno, I. ; Tropin, I.S. /PIP II Collaboration
PIP-II is the Fermilab's flagship project for providing powerful, high-intensity proton beams to the laboratory's experiments. The heart of PIP-II is an 800-MeV superconducting linac accelerator. [...]

Negative Ion Time Projection Chamber operation with SF$_6$ at nearly atmospheric pressure / Baracchini, E. (Frascati ; INFN, Rome ; Rome U.) ; Cavoto, G. (INFN, Rome ; Rome U.) ; Mazzitelli, G. (Frascati) ; Murtas, F. (Frascati ; CERN) ; Renga, F. (INFN, Rome ; Rome U.) ; Tomassini, S. (Frascati)
We present measurements of drift velocities and mobilities of some innovative negative ion gas mixtures at nearly atmospheric pressure based on SF$_{6}$ as electronegative capture agent and of pure SF$_{6}$ at various pressures, performed with the NITEC detector. NITEC is a Time Projection Chamber with 5 cm drift distance readout by a GEMPix, a triple thin GEMs coupled to a Quad-Timepix chip, directly sensitive to the deposited charge on each of the 55 $\times$ 55 $\mu$m$^2$ pixel.

Sympathetic Cooling of Protons and Antiprotons with a Common Endcap Penning Trap / Bohman, M. ; Mooser, A. ; Schneider, G. ; Schön, N. ; Wiesinger, M. ; Harrington, J. ; Higuchi, T. ; Nagahama, H. ; Sellner, S. ; Smorra, C. et al.
We present an experiment to sympathetically cool protons and antiprotons in a Penning trap by resonantly coupling the particles to laser cooled beryllium ions using a common endcap technique. Our analysis shows that preparation of (anti)protons at mK temperatures on timescales of tens of seconds is feasible. [...]

Double-trap measurement of the proton magnetic moment at 0.3 parts per billion precision / Schneider, Georg (Mainz U., Inst. Phys. ; RIKEN (main)) ; Mooser, Andreas (RIKEN (main)) ; Bohman, Matthew (RIKEN (main) ; Heidelberg, Max Planck Inst.) ; Schön, Natalie (Mainz U., Inst. Phys.) ; Harrington, James (Heidelberg, Max Planck Inst.) ; Higuchi, Takashi (RIKEN (main) ; U. Tokyo (main)) ; Nagahama, Hiroki (RIKEN (main)) ; Sellner, Stefan (RIKEN (main)) ; Smorra, Christian (RIKEN (main)) ; Blaum, Klaus (Heidelberg, Max Planck Inst.) et al.
Precise knowledge of the fundamental properties of the proton is essential for our understanding of atomic structure as well as for precise tests of fundamental symmetries. We report on a direct high-precision measurement of the magnetic moment $\mu_p$ of the proton in units of the nuclear magneton $\mu_N$. [...]

Physics with large extra dimensions / Antoniadis, Ignatios (CERN)
A theory with such a mathematical beauty cannot be wrong: this was one of the main arguments in favor of string theory, which unifies all known physical theories of fundamental interactions in a single coherent description of the universe. But no one has ever observed strings, not even indirectly, neither the space of extra dimensions where they live. [...]

RF pulse shape control in the compact linear collider test facility / Kononenko, Oleksiy (SLAC ; CERN) ; Corsini, Roberto (CERN)
The Compact Linear Collider (CLIC) is a study for an electron–positron machine aiming at accelerating and colliding particles at the next energy frontier. The CLIC concept is based on the novel two-beam acceleration scheme, where a high-current low-energy drive beam generates RF in series of power extraction and transfer structures accelerating the low-current main beam.

The CREAM-III Calorimeter / Malinin, A (Maryland U.) ; Lee, M H (Maryland U.) ; Ahn, H S (Maryland U.) ; Ganel, O (Maryland U.) ; Han, J H (Maryland U.) ; Jeon, J A (Ewha Women's U., Seoul) ; Kim, C H (Maryland U.) ; Kim, K C (Maryland U.) ; Lutz, L (Maryland U.) ; Nam, S (Ewha Women's U., Seoul) et al.
After successful recovery of the first CREAM (Cosmic Ray Energetics And Mass) instrument during the 2004\/5 Antarctic campaign, the calorimeter was refurbished for the third launch, planned for December 2007. In this CREAM-III calorimeter, the optics were replaced with multi-clad fiber ribbons to enhance the light signal. [...]
