Mixed-Field Radiation of 3-D MLC Flash Memories for Space Applications / Gonzales, Lorenzo (Maribor U.) ; Danzeca, Salvatore (CERN) ; Fiore, Salvatore (CERN) ; Kramberger, Iztok (Maribor U.)
This article presents the results of dynamic measurements of 3-D multilevel cell (MLC)NANDflash memories in a mixed-field radiation facility CERN High-energy AcceleRator Mixed field/facility (CHARM), CERN. The results show that the behavior of devices is comparable to tests with specific high energy particles, such as high energy protons, heavy ions, and to TID tests. [...]

Effects of Cavity Pre-Detuning on RF Power Transients at Injection into the LHC / Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Argyropoulos, Theodoros (CERN) ; Butterworth, Andrew (CERN) ; Calaga, Rama (CERN) ; Karpov, Ivan (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN)
At injection into the LHC, the RF system is perturbed by beam-induced voltage resulting in strong RF power transients and the instant detuning of the cavities. The automatic tuning system, however, needs time for the mechanical compensation of the resonance frequency to take place. [...]

The CELESTA CubeSat In-Flight Radiation Measurements and Their Comparison With Ground Facilities Predictions / Coronetti, Andrea (CERN) ; Zimmaro, Alessandro (CERN) ; Alía, Rubén García (CERN) ; Danzeca, Salvatore (CERN) ; Masi, Alessandro (CERN) ; Slipukhin, Ivan (CERN) ; Amodio, Alessio (CERN) ; Dijks, Jasper (CERN) ; Peronnard, Paul (CERN) ; Secondo, Raffaello (CERN) et al.
The CELESTA CubeSat has employed radiation monitors developed by the Conseil Européen pour la Recherche Nucléaire (CERN) Centre, used for measuring the radiation environment at accelerators, to measure the space radiation field in a medium-Earth orbit (MEO). The technology is based on three static random-access memories (SRAMs) that are sensitive to single-event upsets (SEUs) and single-event latchups (SELs). [...]

Real-time processing of longitudinal Schottky signals in CERN’s antiproton chain / Niccolini, Marco (CERN) ; Barrientos, Diego (CERN) ; Suminski, Maciej (CERN) ; Angoletta, Maria Elena (CERN) ; Soderen, Martin (CERN) ; Freyermuth, Pierre (CERN) ; Brischetto, Ylenia (CERN)
A low-latency, real-time diagnostic system for the analysis of longitudinal Schottky signals in CERN’s antiproton chain has been developed. The system, installed in CERN’s Antiproton Decelerator (AD), processes the combined output of two low-noise, wideband AC beam transformers. [...]

High-resolution bunch profile measurements for enhanced longitudinal beam diagnostics / Brischetto, Ylenia (CERN) ; Timko, Helga (CERN) ; Argyropoulos, Theodoros (CERN)
Efficient operation of the Large Hadron Collider (LHC) relies on accurate longitudinal beam measurements to diagnose beam instabilities and verify the correctness of bunch-shaping techniques. To achieve this goal, a diagnostic system was developed to perform high-resolution measurements of longitudinal bunch profiles. [...]

Experience with Beam Transfer Function Measurements for Setting-up the Stochastic Cooling System in the CERN Anti-Proton Decelerator (AD) / Rey, Stephane (CERN) ; Bastos, Wilker (CERN) ; Caspers, Fritz (CERN) ; Dupuy, Bruno (CERN) ; Gamba, Davide (CERN) ; Höfle, Wolfgang (CERN) ; Louwerse, Reinier (CERN)
Beam transfer function measurements have regularly been used to set-up the adjustable parameters for stochastic cooling systems. We report on the automation of these measurements at CERN that permit efficient set-up of the cooling loops in the anti-proton decelerator (AD) and enables insight into the bandwidth (nominal frequency range of 850 MHz to 1.7 GHz) of the overall system for the longitudinal, horizontal and vertical cooling at the two different beam momenta of 2 GeV/c and 3.5 GeV/c.

ATF2-3 hardware upgrade and new experimental results to maximize luminosity potential of linear colliders / Faus-Golfe, Angeles (IJCLab, Orsay) ; Aryshev, Alexander (KEK, Tsukuba) ; Lyapin, Alexey (Oxford U.) ; Kruchinin, Konstantin (KEK, Tsukuba) ; Terunuma, Nobuhiro (KEK, Tsukuba) ; Fuster-Martinez, Nuria (Valencia U., IFIC) ; Burrows, Philip (Oxford U.) ; Mazzoni, Stefano (CERN) ; Okugi, Toshiyuki (KEK, Tsukuba) /ATF2 Collaboration
The ATF2-3 beamline is the only facility in the world for testing the Final Focus Beamline of linear colliders and is essential for the ILC and the CLIC projects. A vertical electron beam size of 41 nm (within 10% of the target), a closed-loop intra-bunch feedback of latency 133 ns, and direct stabilization of the beam position at the Interaction Point to 41 nm (limited by IP BPM resolution) have all been achieved at ATF2.

Design, manufacturing and validation of the new quench heater discharge power supplies for the protection of superconducting magnets for the High-Luminosity LHC Project at CERN / Carrillo, David (CERN) ; Berberat, Raphael (CERN) ; Georgakakis, Spyridon (CERN) ; Guasch-Martinez, Josep (CERN) ; Lopez Cordoncillo, Denisse (CERN) ; de Nicolás Lumbreras, Enrique (CERN) ; Nowak, Edward (CERN) ; Papamichali, Maria (CERN) ; Pojer, Mirko (CERN) ; Rodriguez Mateos, Felix (CERN) et al.
The Quench Heater Discharge Power Supplies (HDS) are magnet protection devices installed in the Large Hadron Collider (LHC) that, upon detection of a magnet quench, release energy into strip heaters that are in thermal contact with the superconducting coils, inducing a resistive transition all along the coils. The new HDS design for protection of the High Luminosity LHC (HL-LHC) Inner Triplet magnets calls for a more advanced design with up-to-date components resulting in a high reliability of the HDS units.
