Latest results from the RD42 collaboration on the radiation tolerance of polycrystalline diamond detectors
/ Mali, M (Plymouth U.) ; Artuso, M (Syracuse U. (main)) ; Bäni, L (ETH, Zurich (main)) ; Bartosik, M (CERN) ; Bellini, V (Catania U. ; INFN, Catania) ; Bentele, B (Colorado U.) ; Bergonzo, P (University Coll. London) ; Bes, A (LPSC, Grenoble) ; Brom, J-M (Strasbourg, IPHC) ; Chiodini, G (INFN, Lecce) et al.
As nuclear and particle physics facilities move to higher intensities, the detectors used there must be more radiation tolerant. Diamond is in use at many facilities due to its inherent radiation tolerance and ease of use. [...]

Restriction on the gain in collected charge due to carrier avalanche multiplication in heavily irradiated Si strip detectors
/ Verbitskaya, E (Ioffe Phys. Tech. Inst.) ; Eremin, V (Ioffe Phys. Tech. Inst.) ; Zabrodskii, A (Ioffe Phys. Tech. Inst.) ; Li, Z (Brookhaven Natl. Lab.) ; Luukka, P (Helsinki Inst. of Phys.)
Recent experiments on silicon detectors developed by the CERN-RD50 collaboration for very high luminosity colliders showed a significant enhancement of the collected charge $Q_c$ in Si detectors irradiated to the fluence of $10^{15} – 10^{16} \ \rm{n}_{eq}/cm^2$ if the devices were operated at high bias voltage. The enhancement arises from carrier avalanche multiplication in high electric field of the junction. [...]

Development of silicon detectors for Beam Loss Monitoring at HL-LHC
/ Verbitskaya, E (Ioffe Phys. Tech. Inst.) ; Eremin, V (Ioffe Phys. Tech. Inst.) ; Zabrodskii, A (Ioffe Phys. Tech. Inst.) ; Bogdanov, A (Ioffe Phys. Tech. Inst.) ; Shepelev, A (Ioffe Phys. Tech. Inst.) ; Dehning, B (CERN) ; Bartosik, M R (CERN ; Zurich, ETH) ; Alexopoulos, A (CERN ; TEL, Lamia) ; Glaser, M (CERN) ; Ravotti, F (CERN) et al.
Silicon detectors were proposed as novel Beam Loss Monitors (BLM) for the control of the radiation environment in the vicinity of the superconductive magnets of the High-Luminosity Large Hadron Collider. The present work is aimed at enhancing the BLM sensitivity and therefore the capability of triggering the beam abort system before a critical radiation load hits the superconductive coils. [...]

Beam Loss Monitors for the Cryogenic LHC Magnets
/ Bartosik, Marcin R (CERN) ; Alexopoulos, Andreas (CERN) ; Dehning, Bernd (CERN) ; Eremin, Vladimir (Ioffe Phys. Tech. Inst.) ; Griesmayer, Erich (IAEA, Vienna) ; Sapinski, Mariusz (CERN) ; Verbitskaya, Elena (Ioffe Phys. Tech. Inst.)
The Beam Loss Monitoring system of the Large Hadron Collider close to the interaction points contains mostly gas ionization chambers working at room temperature, located far from the superconducting coils of the magnets. The system records particles lost from circulating proton beams, but is also sensitive to particles coming from the experimental collisions, which do not contribute significantly to the heat deposition in the superconducting coils. [...]

CERN-RD39 collaboration activities aimed at cryogenic silicon detector application in high-luminosity Large Hadron Collider
/ Li, Zheng (Xiangtan U.) ; Eremin, Vladimir (Ioffe Phys. Tech. Inst.) ; Verbitskaya, Elena (Ioffe Phys. Tech. Inst.) ; Dehning, Bernd (CERN) ; Sapinski, Mariusz (CERN) ; Bartosik, Marcin R (CERN) ; Alexopoulos, Andreas (CERN) ; Kurfürst, Christoph (Vienna U.) ; Härkönen, Jaakko (Helsinki Inst. of Phys.)
Beam Loss Monitors (BLM) made of silicon are new devices for monitoring of radiation environment in the vicinity of superconductive magnets of the Large Hadron Collider. The challenge of BLMs is extreme radiation hardness, up to 10 16 protons/cm 2 while placed in superfluid helium (temperature of 1.9 K). [...]

Silicon and diamond detectors operated in a superfluid helium bath are currently being considered for the upgrade of the LHC beam loss monitoring system. The detectors would be installed in immediate proximity of the superconducting coils of the triplet magnets. [...]
