High intensity proton beam impact at 440 GeV/c on Mo and Cu coated CfC/graphite and SiC/SiC absorbers for beam intercepting devices
/ Maestre, Jorge (CERN ; Granada U.) ; Bahamonde, Cristina (CERN) ; Garcia, Inigo Lamas (CERN) ; Kershaw, Keith (CERN) ; Biancacci, Nicolo (CERN) ; Busom, Josep (CERN) ; Frankl, Matthias (CERN ; PSI, Villigen) ; Lechner, Anton (CERN) ; Kurtulus, Adnan (CERN) ; Makimura, Shunsuke (J-PARC ; KEK, Tsukuba) et al.
Beam Intercepting Devices (BIDs) are essential protection elements for the operation of the Large Hadron Collider (LHC) complex. The LHC internal beam dump (LHC Target Dump Injection or LHC TDI) is the main protection BID of the LHC injection system; its main function is to protect LHC equipment in the event of a malfunction of the injection kicker magnets during beam transfer from the SPS to the LHC.

Collimation of partially stripped ions in the CERN Large Hadron Collider
/ Gorzawski, Arkadiusz (CERN ; Malta U.) ; Abramov, Andrey (CERN ; JAI, UK) ; Bruce, Roderik (CERN) ; Fuster-Martínez, Nuria (CERN) ; Krasny, Mieczyslaw (CERN ; Paris U., VI-VII) ; Molson, James (CERN) ; Redaelli, Stefano (CERN) ; Schaumann, Michaela (CERN)
In the scope of the Physics Beyond Colliders studies, the Gamma-Factory initiative proposes the use of partially stripped ions as a driver of a new type of high-intensity photon source in CERN Large Hadron Collider (LHC). In 2018, the LHC accelerated and stored partially stripped $^{208}\text{Pb}^{81+}$ ions for the first time. [...]

NA62 Liquid Krypton Purity Monitor
/ Bremer, Johan (CERN) ; Bryman, Douglas (British Columbia U. ; TRIUMF) ; Danielsson, Hans (CERN) ; Falaleev, Valeri (Dubna, JINR ; INFN, Perugia) ; Koettig, Torsten (CERN) ; Kurchaninov, Leonid (TRIUMF) ; Liberadzka-Porret, Joanna (CERN) ; Onufrena, Aleksandra (CERN) ; Velghe, Bob (TRIUMF)
A system for determining the purity of liquid krypton employed in the NA62 rare kaon decay experiment at CERN was developed based on the use of a time projection chamber. The attenuation of drifting ionization electrons from absorption of 511 keV gamma rays in liquid krypton was measured to estimate the purity. [...]
