(UCLA, Los Angeles (main) ; Tektronix, Irvine) ; Turner, D.L. (UCLA, Los Angeles (main) ; Johns Hopkins U.) ; Runov, A. (UCLA, Los Angeles (main)) ; Li, W. (UCLA, Los Angeles (main) ; Boston U.) ; Liu, J. (UCLA, Los Angeles (main)) ; Artemyev, A.V. (UCLA, Los Angeles (main)) ; Zhang, X.-J. (UCLA, Los Angeles (main)) et al.
The Electron Loss and Fields Investigation with a Spatio-Temporal Ambiguity-Resolving option (ELFIN-STAR, or simply: ELFIN) mission comprises two identical 3-Unit (3U) CubeSats on a polar (~93deg inclination), nearly circular, low-Earth (~450 km altitude) orbit. Launched on September 15, 2018, ELFIN is expected to have a >2.5 year lifetime. [...]

Analysis of the Leakage Events in the Thermal Shield Cooling Pipes of the ITER Magnet System
/ Sgobba, Stefano (CERN) ; Santillana, Ignacio Aviles (CERN) ; Celuch, Michal (CERN) ; Crouvizier, Mickaël (CERN) ; Perez Fontenla, Ana Teresa (CERN) ; Castro, Enrique Rodriguez (CERN) ; Mitchell, Neil (Euratom, St. Paul Lez Durance) ; Koizumi, Norikiyo (Euratom, St. Paul Lez Durance) ; Pearce, Robert (Euratom, St. Paul Lez Durance) ; Worth, Liam (Euratom, St. Paul Lez Durance) et al.
The ITER Thermal Shields (TS) consist of actively cooled stainless steel panels. Their role is to minimise the radiation heat load from warm components, such as the Vacuum Vessel (VV) and the cryostat, hence contributing to insulating the magnet system operating at 4.5 K. [...]

The High Luminosity Large Hadron Collider (HL-LHC) is a major upgrade to the existing Large Hadron Collider (LHC) at CERN, aimed at increasing the integrated luminosity of the collider by a factor of ten [1]. A key component of the HL-LHC are the superconducting Nb3Sn quadrupole magnets, known as MQXF, whose purpose is to focus the particle beam [3]. [...]

/ATLAS Collaboration
The ATLAS experiment Data Acquisition (DAQ) system will face an extensive upgrade to fully exploit the High-Luminosity LHC (HL-LHC) upgrade, allowing it to record data at unprecedented rates. The detector will be read out at 1 MHz generating over 5 TB/s of data which is sent to approximately 600 servers. [...]
