Evaluation of HPK n plus -p planar pixel sensors for the CMS Phase-2 upgrade

Konstantin Androsov, Varun Sharma, Xin Chen, Rakesh Chawla, Werner Lustermann, Andromachi Tsirou, Alexis Kalogeropoulos, Andrea Rizzi, Thomas Muller, David Vannerom

To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determine ...

Test beam performance of a CBC3-based mini-module for the Phase-2 CMS Outer Tracker before and after neutron irradiation

Simone Scarfì, Varun Sharma, Konstantin Androsov, Xin Chen, Rakesh Chawla, Werner Lustermann, Andromachi Tsirou, Alexis Kalogeropoulos, Andrea Rizzi, Thomas Muller

The Large Hadron Collider (LHC) at CERN will undergo major upgrades to increase the instantaneous luminosity up to 5-7.5 x 1034 cm-2s-1. This High Luminosity upgrade of the LHC (HL-LHC) will deliver a total of 3000-4000 fb-1 of proton-proton collisions at ...

Beam test performance of a prototype module with Short Strip ASICs for the CMS HL-LHC tracker upgrade

Simone Scarfì, Qian Wang, Varun Sharma, Konstantin Androsov, Xin Chen, Rakesh Chawla, Tian Cheng, Werner Lustermann, Andromachi Tsirou, Andrea Rizzi

The Short Strip ASIC (SSA) is one of the four front-end chips designed for the upgrade of the CMS Outer Tracker for the High Luminosity LHC. Together with the Macro-Pixel ASIC (MPA) it will instrument modules containing a strip and a macro-pixel sensor sta ...

Synthesizing efficient systems in probabilistic environments

Barbara Jobstmann, David Parker

We present a formalism, algorithms and tools to synthesise reactive systems that behave efficiently, i.e., which achieve an optimal trade-off between a given cost and reward model. Synthesis aims to automatically generate a program from a specification. Mo ...

Superconductivity in semimetallic Bi3O2S3

Henrik Moodysson Rønnow, Lin Yang, Peter Babkevich, David Parker

Here we report a further investigation on the thermodynamic and transport properties, and an assessment of theoretical calculations, for the BiS2- layered Bi3O2S3 superconductor. The polycrystalline sample is synthesized with a superconducting transition t ...

Altered Gaba And Somatostatin Modulation Of Proprioceptive Feedback After Spinal Cord Injury In Lamprey

David Parker

While various changes occur after spinal cord lesions, their influence on functional recovery is generally unclear. We have shown changes in proprioceptor and locomotor network properties below lesion sites in the lamprey spinal cord. The proprioceptive sy ...
