Comparison of High Energy X-Ray and Cobalt-60 Irradiations on MOS Capacitors / Girones, Vincent (Montpellier U.) ; Boch, Jérôme (Montpellier U.) ; Saigné, Frédéric (Montpellier U.) ; Carapelle, Alain (CERN) ; Chapon, Arnaud ; Maraine, Tadec (Montpellier U.) ; Alía, Rubén García (CERN)
The use of a high energy X-ray generator for Total Ionizing Dose (TID) testing is studied on metal-oxide semiconductor (MOS) capacitors. Several conditions were studied for the high energy X-ray irradiations (with aluminum and lead filters) and the experimental results are compared to Cobalt 60 (Co-60) irradiations. [...]

Stable 500 kW average power of infrared light in a finesse 35,000 enhancement cavity / Lu, Xin-Yi (Tsinghua University)
Advances in laser technology over the past 25 years have been impressive, in particular for the Ytterbium technology where nowadays kW-class laser systems are available. This technology also led to the possibility to provide hundreds of kilowatts of laser power by the use of enhancement cavities. [...]

Diffusion of Implanted 195Au Radiotracer Atoms in Amorphous Silicon under Irradiation with 1 Mev-N+ Ions / Voss, T (Stuttgart, Max Planck Inst.) ; Scharwaechter, P (Stuttgart, Max Planck Inst.) ; Frank, W (Stuttgart, Max Planck Inst. ; CERN) /ISOLDE Collaboration
The diffusion of implanted $^{195}$Au in Au-doped amorphous Si was studied, partly under N$^+$-irradiation by means of a radiotracer technique, in which the serial sectioning of the specimens was done by Ar$^+$-beam sputtering. It was found that high implantation doses in combination with great diffusion lengths give rise to complicated shapes of the diffusion profiles. [...]

Quench Protection of the HL-LHC Hollow Electron Lens Superconducting Solenoid Magnets / Wozniak, Mariusz (CERN) ; Foussat, Arnaud (CERN) ; Yammine, Samer (CERN) ; Steckert, Jens (CERN) ; Ravaioli, Emmanuele (CERN) ; Verweij, Arjan (CERN) ; Kolehmainen, Antti (CERN) ; Redaelli, Stefano (CERN) ; Rossi, Adriana (CERN)
The High-Luminosity LHC (HL-LHC) project is an upgrade of the Large Hadron Collider (LHC) and comprises the installation of two Hollow Electron Lens (HEL) systems, each acting on one beam on both sides of LHC Point 4. The systems aim for a controlled depletion of hadron beam tails and an enhanced hadron beam halo collimation. [...]

Construction and Test of the Enhanced Racetrack Model Coil, First CERN R&D; Magnet for the FCC / Perez, J C (CERN) ; Bajko, M (CERN) ; Bourcey, N (CERN) ; Bordini, B (CERN) ; Bottura, L (CERN) ; Troitiño, S Ferradás (CERN) ; Gautheron, E (CERN) ; Guinchard, M (CERN) ; Bermudez, S Izquierdo (CERN) ; Mangearotti, F (CERN) et al.
Racetrack model coils (RMC) have been built at CERN during the past decade, as an R&D; tool to qualify conductors and technologies developed for high field superconducting accelerator magnets (Perez et al. , 2016). RMC, assembled in a dipole magnet configuration, proved to be an efficient instrument reducing cost and feed-back time while developing new magnets. [...]

An Enhanced Sensitivity Operation Mode for Floating Gate Dosimeters / Rizzo, Marta (CERN ; Milan, Polytech.) ; Brucoli, Matteo (CERN) ; Danzeca, Salvatore (CERN) ; Masi, Alessandro (CERN) ; Pineda, Àlvaro (Unlisted, ES) ; Mas, Bartomeu Servera (Unlisted, ES)
A new method for enhancing the sensitivity of the Floating Gate DOSimeter (FGDOS) has been investigated. By increasing the electric field in the silicon dioxide, it is possible to improve the fractional yield of collection of the electron–hole pairs, thus to increase the device’s sensitivity. [...]

Mechanical Tests, Analysis, and Validation of the Support Structure of the eRMC and RMM Magnets of the FCC R&D at CERN / Pérez, Manuel García (CERN) ; Izquierdo Bermudez, Susana (CERN) ; Perez, Juan Carlos (CERN) ; Bourcey, Nicolas (CERN) ; Grosclaude, Philippe (CERN) ; Guinchard, Michael (CERN) ; Tommasini, Davide (CERN) ; Naini, Sohrab Emami (CERN) ; Ferradas Troitiño, Salvador (CERN)
The enhanced racetrack model coil and racetrack model magnet constitute the current R&D; Nb$_3$Sn magnets under development at CERN aiming to achieve dipole fields of 16-18 T, the design baseline of the Future Circular Collider (FCC). This article reports the mechanical behavior of their common support structure, which underwent three different levels of room-temperature preload (with the bladders and key method) and two cooldown cycles to 80 K.
