This paper presents a novel application of Path Following and Nonlinear Model Predictive Control techniques to a tendon-actuated snake robot with rolling joints. The study investigates the efficacy of NMPC in guiding the robot’s end-effector along predefined trajectories in the robot output space, emphasizing its relevance for inspection and maintenance tasks in cluttered environments where traditional manipulators may be impractical or ineffective.

High-Voltage studies in the new GE1/1 GEM station at CMS experiment / Di Fraia, Carlo (Naples U. ; INFN, Naples) /CMS Muon Collaboration
Part of the muon upgrade of the CMS Experiment for the High-Luminosity Large Hadron Collider consists of three new GEM stations, GE1/1, GE2/1 and ME0. The purpose of these stations is to increase the redundancy of the CMS muon spectrometer in the forward endcap regions and to extend the acceptance of the detector up to a pseudorapidity |η| ∼ 2.8 with the ME0 station.

Upgrade of the CMS Drift Tube electronics for the High Luminosity LHC / Redondo, I (Madrid, CIEMAT) /CMS Collaboration
The electronics of the CMS Drift Tubes (DT) chambers will be replaced to operate during High Luminosity (HL-LHC). In the upgraded architecture, optical links (lpGBT, VTRX+) send all signals to the backend, where complex logic running on FPGAs will process the data within trigger latency with precision enough to profit from the full chamber resolution, which in the present system is only possible offline.

Investigation of non-idealities of pulsing circuitry in the ALICE ITS3 MOSS monolithic sensor / Emiliani, S (CERN) ; Aglieri Rinella, G (CERN) ; Lemoine, C (CERN ; Strasbourg, IPHC) ; Piro, F (CERN) ; Ripamonti, G (CERN) ; Snoeys, W (CERN) ; Suljic, M (CERN) ; Terlizzi, L (Turin U.)
The MOSS wafer-scale monolithic sensor, designed for the vertex detector (ITS3) of the ALICE experiment, features a pixel input capacitance of ∼ 5 fF. Such a small input capacitance is needed to reach a satisfactory SNR with a low-power analog front-end (36 nW/pixel). [...]

EMCI-EMP: developments and experience with the novel detector control solution / Ecker, D (Wuppertal U. ; CERN) ; Dubru, P (CERN) ; Foged, S (Aarhus U.) ; Kanellos, N (CERN ; Natl. Tech. U., Athens) ; Moschovakos, P (CERN) ; Ryjov, V (CERN) ; Schlenker, S (CERN)
The Embedded Monitoring and Control Interface (EMCI) and Embedded Monitoring Processor (EMP) system is a state-of-the-art solution developed for the Detector Control System (DCS) upgrade in the ATLAS experiment. The EMCI serves as a radiation-tolerant interface for control and monitoring data of the detector Front-End electronics. [...]

Development of the ATLAS Liquid Argon Calorimeter on-detector readout electronics for the HL-LHC / Panchal, D (Texas U.) /ATLAS Liquid Argon Calorimeter Collaboration
The High-Luminosity LHC will start operations for physics in 2029 and aims to record 3000 fb$^{-1}$ of proton collision data. This expansion of the dataset will be achieved by afour-fold increase in the number of collisions per bunch crossing, leading to∼ 10× higher radiation doses and busier events. [...]

Pileup mitigation in Hadron Forward calorimeter at the Level-1 trigger of the CMS experiment for the HL-LHC / Ghodgaonkar, Abhijeet (Tata Inst.) ; Sugunan, Aravind Thachayath (Tata Inst.) ; Govekar, Pranav Keshav (Tata Inst.) ; Patil, Mandakini Ravindra (Tata Inst.) ; Mazumdar, Kajari (Tata Inst.) /CMS Collaboration
The high luminosity operation of the LHC will deliver collisions with a luminosity about 10 times the original design value. This poses a big challenge for trigger and data acquisition due to nearly 200 overlapping collisions, called pile up, within the same bunch crossing. [...]

The services chain for the upgrade of the Inner Tracker Pixel detector of the ATLAS experiment. Full services from pixel modules to optical readout for the Outer Barrel sub-system / Zografos, A (CERN) ; Buytaert, J (CERN) ; Kuehn, S (CERN) ; Quadt, A (Gottingen U., II. Phys. Inst.) ; Skaf, A (Gottingen U., II. Phys. Inst.) ; Thys-dingou, O (Gottingen U., II. Phys. Inst.)
For the high-luminosity upgrade of the ATLAS Inner Tracking detector, a new pixel detector will be installed to increase bandwidth and to cope with higher radiation, among other challenges. In this contribution, the design aspects and qualification of the data transmission from pixel modules to optical readout are presented. [...]

An FPGA-agnostic system for achieving picosecond-level phase determinism in timing distribution links for High Energy Physics experiments / Orzes, E (CERN) ; Baron, S (CERN) ; Mendes, E (CERN) ; Rusack, R (Minnesota U.) ; Eberle, Z (Minnesota U.) ; Saradhy, R (Minnesota U.) ; Tousi, Y (Minnesota U.) ; Frahm, E (Minnesota U.) ; Martina, F (CERN) ; Vichoudis, P (CERN)
Picosecond-level phase determinism in timing distribution systems is a requirement for future detectors in High Energy Physics. FPGA transceivers traditionally used to propagate timing signals generally do not meet this stringent requirement, suffering from phase jumps at startup and from drifts due to temperature variations.

Optimized rad-hard DC/DC converters for HEP applications / van der Blij, Nils H (CERN) ; Koseoglou, Sokratis (CERN) ; Bantemits, Georgios (CERN) ; Ripamonti, Giacomo (CERN) ; Michelis, Stefano (CERN)
The development of 48 V compatible DC/DC converters that are tolerant to high magnetic fields and radiation helps to reduce the cost and weight of the cabling, power supplies and cooling of High Energy Physics (HEP) experiments.In this paper, a new, optimized and compact bPOL48V module is presented aimed at 48 V to 5–12 V power conversion.This new module, which is available for purchase and as a reference design, reduces the size by 93% compared to previous designs while exhibiting similar efficiency.Furthermore, a framework for optimizing and comparing converter topologies is also introduced, which identifies the 3-level buck topology as a promising topology for future research and development.Moreover, experimental validation of different optimized converters is also provided.The experimental results show that the 3-level buck topology is promising for 48 V to 5 V conversion stages, and that the Berkeley buck topology is promising for the development of 48 V to 1 V conversion stages..
