Mechanical Design of the High Luminosity Large Hadron Collider (HL-LHC) Beam Screen through a Multiphysics Model / Morrone, Marco (Imperial Coll., London ; CERN) ; Garion, Cedric (CERN) ; Aurisicchio, Marco (Imperial Coll., London) ; Chiggiato, Paolo (CERN)
A novel numerical model to estimate the mechanical behaviour of the new HL - LHC beam screen duri ng a magnet quench is presented. The temperature rise due to the resistive losses of the induced currents is considered [...]

STF-2 Cryomodule Performance and New Input Coupler R&D; for ILC / Yamamoto, Yasuchika (KEK, Tsukuba) ; Honma, Teruya (KEK, Tsukuba) ; Kako, Eiji (KEK, Tsukuba) ; Kojima, Yuuji (KEK, Tsukuba) ; Matsumoto, Toshihiro (KEK, Tsukuba) ; Michizono, Shinichiro (KEK, Tsukuba) ; Nakai, Hirotaka (KEK, Tsukuba) ; Shishido, Toshio (KEK, Tsukuba) ; Yamamoto, Akira (KEK, Tsukuba) ; Julie, Charles (CERN) et al.
The high power test for STF -2 cryomodule with twelve cavities has completed successfully in 2015. It became clear the average accelerating gradient was 30.3 MV/m, eight cavities achi eved above 31.5 MV/m as the ILC specification, and three cavities had the significant performance degradation by heavy field emission due to the additional clean room work in t he STF tunnel.

Using basic electromagnetism to introduce LINAC4 (CERN) / Cid-Vidal, Xabier (CERN) ; Cid, Ramon (Santiago de Compostela, IES) ; Vretenar, Maurizio (CERN)
The LHC is the last element of CERN’s accelerator complex, which is a succession of machines with increasingly higher energies. Everything starts in the 50 MeV linear accelerator (LINAC2), but a new linear accelerator, the 160 MeV LINAC4, will replace LINAC2 in 2018, upgrading LHC injectors to higher intensity and eventually increasing the luminosity of LHC.

Is the mystery of the masses of elementary particles solved? / Arneth, Borros (Bad Homburg)
An explanation of the masses of baryons and mesons is still one of the great unsolved mysteries of physics and poses a significant challenge for our time. In this paper, a novel approach is presented that could shed light on this issue by proposing a new form of energy that has not been considered to date. [...]

Thermophysical and mechanical characterization of advanced materials for the LHC collimation system / Bianchi, Laura
The aim of the thesis is to describe the methods employed for the thermo-physical and mechanical characterization and to show the results of the campaign conducted over two ceramic matrix composites, CFC FS140® and MG-6403-Fc, which are candidates as jaws materials in the LHC collimation system [...]

Vol. 39 - Cryogenic Fiber Optic Sensors for Superconducting Magnets and Power Transmission Lines in High Energy Physics Applications / Chiuchiolo, Antonella (University of Sannio) ; Cusano, Andrea (dir.) (University of Sannio) ; Bajko, Marta (dir.) (CERN)
In the framework of the Luminosity upgrade of the Large Hadron Collider (HL - LHC), a remarkable R&D; effort is now ongoing at the European Organization for Nuclear Research (CERN) in order to develop a new generation of accelerator magnets and superconducting power transmission lines. The magnet technology will be based on Nb3Sn enabling to operate in the 11 - 13 T range. [...]

Discussion of the introduction of a new complex physical quantity into physics / Arneth, Borros (Bad Homburg)
Here we present a new physical quantity with the aim of unifying the structure of physics. The basic assumption starts with a reduction of all natural forces into a single force. [...]
