94. Measurement of effective space charge concentration vs. neutron fluence in p-type substrates from LFoundry

Igor Mandić (Jozef Stefan Institute (SI))

27/02/2019, 14:00

Oral

RD50 submitted a pixel detector prototype ASIC in 150 nm CMOS technology at LFoundry. The chip contains passive pixel arrays near the edge of the chip suitable for E-TCT measurements. The chips were manufactured on p-type silicon with two different initial resistivities. Chips were irradiated with neutrons in the Triga reactor in Ljubljana to several fluences up to maximal fluence of 2e15...

125. Transient Current Technique characterization of HV-CMOS sensor prototypes after irradiation

Ettore Zaffaroni (Universite de Geneve (CH))

Oral

Silicon detectors built in high-voltage and high-resistivity CMOS technology are an interesting options for the outermost pixel layers of ITk (Inner Tracker), the new all-silicon tracking system foreseen for the ATLAS experiment upgrade for the high luminosity LHC program. They are less expensive and easier to produce with respect to standard hybrid silicon pixel detectors, which would...

123. Design optimisation of depleted CMOS detectors using TCAD simulations within the CERN-RD50 collaboration

Matthew Lewis Franks

Oral

In this work we report the main TCAD simulation results of a depleted CMOS detector designed in the 150 nm HV-CMOS process from LFoundry. These results have been used in the design of a test chip, the second prototype developed by the CERN-RD50 collaboration (RD50-MPW2), recently submitted for fabrication. The main aim of this study is to optimise the leakage problem seen in laboratory...

130. Parametrisation of the response of ALPIDE Monolithic Active Pixel Sensors to low energy nuclei

Ester Ricci (Universita degli Studi di Trento and INFN (IT))

27/02/2019, 15:00

Oral

We report on the characterisation of the response of the ALPIDE MAP
sensor to nuclei of energy 20-220 MeV/a.m.u.. ALPIDE has been designed
for the upgrade of ALICE experiment at the LHC: the new tracker will be
fully efficient, with improved sensitivity, for particles with
transverse velocity larger than 0.7c and charge ±1. The operating regime
considered in this work is really different:...

81. The PERCIVAL soft X-ray Detector

Jonathan Correa Magdalena (Deutsches Elektronen-Synchrotron DESY)

Oral

The PERCIVAL collaboration to develop a soft X-ray imager able to address the challenges of high brilliance light sources such as new-generation synchrotrons and Free Electron Lasers, has reached one of its major milestones: a full 2-MegaPixel (P2M) system (uninterrupted 4 x 4 cm2 active area) has already seen its first light.

Smaller prototypes of the device, a monolithic active pixel sensor...
