Optical Cherenkov Radiation (ChR) is a well-known type of radiation, which is utilized in different fields of physics such as charged particle detection or generation of intense THz radiation. It is also widely used in beam diagnostics, for instance, in beam loss monitors or for bunch length measurements. [...]

FLASH, the XUV and soft X-ray free-electron laser at DESY, is currently undergoing the 2nd of two long upgrade shutdowns within the FLASH2020+ project. The 1st half of 2024 was dedicated to user operation. [...]

Various methods to measure the dynamic behavior of particles require the calculation of autocorrelation functions. For this purpose, fast multi-tau correlators have been developed in dedicated hardware, in software, and on FPGAs. [...]

This paper addresses the mode switching problem in piecewise smooth implicit multilinear initial value problems (IVPs), which are relevant for modeling hybrid dynamical systems like HVAC and power systems. Unlike traditional switched systems with explicit mode descriptions, this work focuses on systems where mode information is implicitly encoded in binary-valued variables and switching conditions are defined by inequality constraints. [...]

The physics program of the HL-LHC requires high-precision (≲1%) luminosity determination. Two new luminosity detectors are being developed by the CMS BRIL (Beam Radiation, Instrumentation, and Luminosity) project: the Fast Beam Condition Monitor (FBCM), a standalone detector with unique timing capabilities, and the Tracker Endcap Pixel (TEPX) detector augmented with real-time cluster reconstruction in the FPGA of a dedicated back-end board at 10% of the full level-1 trigger rate. [...]

The Worldwide Large Hadron Collider Computing Grid (WLCG) community’s deployment of dual-stack IPv6/IPv4 on its worldwide storage infrastructure has been very successful. Dual-stack is not, however, a viable longterm solution; the HEPiX IPv6 Working Group has focused on studying where and why IPv4 is still being used, and how to flip such traffic to IPv6. [...]

The National analysis Facility (NAF) at DESY has constantly been evolving since its inception in 2007. Starting as a distributed computing platform between the DESY sites in Hamburg and Zeuthen, it has been serving the German HEP users as well as international collaborators since as a experimentagnostic compute and data infrastructure. [...]

DESY (Deutsches Elektronen-Synchrotron) has been a center of German high energy physics (HEP) research since 1959 with on-site experiments and theoretical research. Since the turn of the century, the research scope has evolved beyond HEP. [...]
