 LGAD and 3D as Timing Detectors / Ugobono, Sofia Otero (Barcelona, Inst. Microelectron.) /RD50 Collaboration In view of the High Luminosity upgrade of the CERN Large Hadron Collider (HL-LHC), radiation tolerant silicon sensors are being developed in the framework of ATLAS, CMS, RD50 and other sensor R\&D; projects. The HL-LHC beam parameters and hardware configuration should enable the collider to reach a peak instantaneous luminosity of $5\times10^{34}\textrm{ cm}^{-2}\textrm{s}^{-1}$, and an integrated luminosity of 250 fb$^{-1}/\textrm{year}$ with the goal of 3000 fb$^{-1}$ after about 12 years of operation.

 Radiation-tolerant Silicon Detectors for the LHC Phase-II Upgrade and Beyond: Review of RD50 Activities / Ott, Jennifer (Helsinki U. ; Helsinki U. of Tech.) /RD50 Collaboration At the LHC Phase-II Upgrade foreseen for 2027, the particle densities and radiation levels will increase by roughly an order of magnitude compared to the present LHC conditions, and the silicon-based inner tracking systems have to be able to withstand ﬂuences of up to 2$\times$ 16$^{16}$ n$_{eq}$/cm$^{2}$. To mitigate the increased pileup at the HL-LHC, dedicated timing detectors are employed.Within the CERN RD50 Collaboration, a large RD program has been underway for more than a decade across experimental boundaries to develop silicon sensors with sufﬁcient radiation tolerance for HL-LHC tracking and timing detectors.

 Radiation damage in p-type EPI silicon pad diodes irradiated with protons and neutrons / Gurimskaya, Yana (CERN) ; Dias De Almeida, Pedro (CERN ; Cantabria U., Santander) ; Fernandez Garcia, Marcos (Cantabria U., Santander) ; Mateu Suau, Isidre (CERN) ; Moll, Michael (CERN) ; Fretwurst, Eckhart (Hamburg U.) ; Makarenko, Leonid (Belarus State U.) ; Pintilie, Ioana (Bucharest, Nat. Inst. Mat. Sci.) In view of the HL-LHC upgrade, radiation-tolerant silicon sensors containing low-resistivity p-type implants or substrates, like LGAD or HV-CMOS devices, are being developed in the framework of ATLAS, CMS, RD50 and other sensor R&D; projects. These devices are facing a particular problem — the apparent deactivation of the doping due to the irradiation, the so-called acceptor removal effect.

 Development of RD50-MPW2: a high-speed monolithic HV-CMOS prototype chip within the CERN-RD50 collaboration / Zhang, Chenfan (Liverpool U. ; Fond. Bruno Kessler, Trento) ; Casse, Gianluigi (Liverpool U. ; Fond. Bruno Kessler, Trento) ; Massari, Nicola (Fond. Bruno Kessler, Trento) ; Vilella, Eva (U. Liverpool (main)) ; Vossebeld, Joost (U. Liverpool (main)) The CERN-RD50 collaboration has ongoing research to further develop monolithic High Voltage-CMOS (HV-CMOS) sensors in a 150 nm process for future particle physics experiments. As a part of this research programme, a test chip (RD50-MPW2) that implements new methodologies for low leakage current and fast and low-noise readout circuitry has been designed and submitted for fabrication.

 Recent developments of the CERN RD50 collaboration / Menichelli, David (U. Florence (main) ; INFN, Florence) /CERN RD50 The objective of the RD50 collaboration is to develop radiation hard semiconductor detectors for very high luminosity colliders, particularly to face the requirements of the possible upgrade of the large hadron collider (LHC) at CERN. Some of the RD50 most recent results about silicon detectors are reported in this paper, with special reference to: (i) the progresses in the characterization of lattice defects responsible for carrier trapping; (ii) charge collection efficiency of n-in-p microstrip detectors, irradiated with neutrons, as measured with different readout electronics; (iii) charge collection efficiency of single-type column 3D detectors, after proton and neutron irradiations, including position-sensitive measurement; (iv) simulations of irradiated double-sided and full-3D detectors, as well as the state of their production process.. 2008 - 5 p. - Published in : Nucl.
