The integration of heterogeneous resources in the CMS Submission Infrastructure for the LHC Run 3 and beyond / Pérez-Calero Yzquierdo, Antonio (Madrid, CIEMAT ; PIC, Bellaterra) ; Mascheroni, Marco (UC, San Diego) ; Kizinevic, Edita (CERN) ; Khan, Farrukh Aftab (Fermilab) ; Kim, Hyunwoo (Fermilab) ; Flechas, Maria Acosta (Fermilab) ; Tsipinakis, Nikos (CERN) ; Haleem, Saqib (NCP, Islamabad) /CMS Collaboration
While the computing landscape supporting LHC experiments is currently dominated by x86 processors at WLCG sites, this configuration will evolve in the coming years. LHC collaborations will be increasingly employing HPC and Cloud facilities to process the vast amounts of data expected during the LHC Run 3 and the future HL-LHC phase. [...]

Repurposing of the Run 2 CMS High Level Trigger Infrastructure as a Cloud Resource for Offline Computing / CMS Collaboration
The former CMS Run 2 High Level Trigger (HLT) farm is one of the largest contributors to CMS compute resources, providing about 25k job slots for offline computing. This CPU farm was initially employed as an opportunistic resource, exploited during inter-fill periods, in the LHC Run 2. [...]

HPC resources for CMS offline computing: An integration and scalability challenge for the Submission Infrastructure / Pérez-Calero Yzquierdo, Antonio (Madrid, CIEMAT ; PIC, Bellaterra) ; Mascheroni, Marco (UC, San Diego) ; Kizinevic, Edita (CERN) ; Khan, Farrukh Aftab (Fermilab) ; Kim, Hyunwoo (Fermilab) ; Flechas, Maria Acosta (Fermilab) ; Tsipinakis, Nikos (CERN) ; Haleem, Saqib (NCP, Islamabad) /CMS Collaboration
The computing resource needs of LHC experiments are expected to continue growing significantly during the Run 3 and into the HL-LHC era. The landscape of available resources will also evolve, as High Performance Computing (HPC) and Cloud resources will provide a comparable, or even dominant, fraction of the total compute capacity.

The optimization, design and performance of the FBCM23 ASIC for the upgraded CMS beam monitoring system / Kaplon, Jan (CERN) ; Wegrzyn, Grzegorz (CERN) ; Shibin, Konstantin (CERN ; NICPB, Tallinn) ; Barendregt, Marnix (CERN ; Cambridge U.)
We present the development of the FBCM23 ASIC designed for the Phase-II upgrade of the Fast Beam Condition Monitoring (FBCM) system built at the CMS experiment which will replace the present luminometer based on the BCM1F ASIC [1]. The FBCM system should provide reliable luminosity measurement with 1ns time resolution enabling the detection of beam-induced background. [...]

Status and prospects of the HL-LHC project / Zerlauth, Markus (CERN) ; Brüning, Oliver (CERN)
This contribution summarizes the status of preparations and series production of key technologies for the HL-LHC upgrade project. The upgrade will be deployed in the LHC tunnel at the end of the currently ongoing third operational run of the LHC, by creating new underground areas and upgrading the existing LHC equipment, aiming to increase the data set collected by the main LHC experiments by another order of magnitude and starting operation as of 2029..

Status of the International Muon Collider Complex Study at 10 TeV / Skoufaris, Kyriacos (CERN) /International Muon Collider Collaboration
A circular muon collider, due to strong suppression of synchrotron radiation (muons are about 207 times heavier than electrons), can provide high energy (multi-TeV) collisions using fundamental (point-like) particles improving that way the energy frontiers of lepton-antilepton machines. A unique feature of muon colliders, is the significant increase of the luminosity per beam power with beam energy. [...]

Innovations in the Next Generation Medical Accelerators for Therapy with Ion Beams / Benedetto, E (Unlisted, CH) ; Vretenar, M (CERN)
Modern hadron-therapy accelerators have to provide high intensity beams for innovative dose-delivery modalities such as FLASH, pencil beams for 3D scanning, as well as multiple ions with radio-biological complementarity. They need to be compact, cheap and have a reduced energy footprint. [...]
