Benchmarking massively-parallel Analysis Grand Challenge workflows using Snakemake and REANA
/ Donadoni, Marco (CERN) ; Feickert, Matthew (U. Wisconsin, Madison (main)) ; Held, Alexander (U. Wisconsin, Madison (main)) ; Povsten, Andrii (Princeton U. (main)) ; Shadura, Oksana (U. Nebraska, Lincoln) ; Šimko, Tibor (CERN)
We have created a Snakemake computational analysis workflow corresponding to the IRIS-HEP Analysis Grand Challenge (AGC) example studying ttbar production channels in the CMS open data. We describe the extensions to the AGC pipeline that allowed porting of the notebook-based analysis to Snakemake. [...]

Thoroughly testing and integrating hundreds of Pull Requests per month: ROOT’s new Cost-efficient and Feature Rich GitHub-based CI
/ Piparo, Danilo (CERN) ; Naumann, Axel (CERN) ; Muzaffar, Shahzad (CERN) ; Morud, Ole (CERN) ; Canal, Philippe (Fermilab) ; Hageböck, Stephan (CERN) ; Vasilev, Vassil (Princeton U. (main))
ROOT is an open source framework, freely available on GitHub, at the heart of data acquisition, processing and analysis of HE(N)P experiments, and beyond. It is developed collaboratively: contributions are not authored only by ROOT team members, but also by the user community at large: developers and scientists from universities, labs as well as the private sector.

FPGA-RICH: A low-latency, high-throughput online partial particle identification system for the NA62 experiment
/ Perticaroli, Pierpaolo (INFN, Rome) ; Ammendola, Roberto (U. Rome 2, Tor Vergata (main)) ; Biagioni, Andrea (INFN, Rome) ; Chiarini, Carlotta (INFN, Rome) ; Ciardiello, Andrea (U.

FPGA-RICH is an FPGA-based online partial particle identification system for the NA62 experiment utilizing Artificial Intelligence (AI) techniques. Integrated between the readout of the Ring Imaging Cherenkov detector (RICH) and the low-level trigger processor (L0TP+), FPGA-RICH implements a fast pipeline to process in real-time the RICH raw hit data stream, producing trigger-primitives containing elaborate physics information, such as the number of charged particles in a physics event, that L0TP+ can use to improve trigger decision selectivity.

H11(0) end cells for a 750 MHz IH structure
/ Moreno, Gabriela (Madrid, CIEMAT) ; Giner Navarro, Jorge (Madrid, CIEMAT) ; Gavela, Daniel (Madrid, CIEMAT) ; Calvo, Pedro (Madrid, CIEMAT) ; Leon Lopez, Miguel (Madrid, CIEMAT) ; Rodriguez Paramo, Angel (Madrid, CIEMAT) ; Oliver, Concepcion (Madrid, CIEMAT) ; Perez Morales, Jose (Madrid, CIEMAT) ; Carmona, José Miguel (Unlisted, ES) ; Alvarado Martin, Maria (Unlisted, ES) et al.
This article presents a study on the H11(0) end cell of an IH-DTL prototype for accelerating carbon ion beams from 5 to 5.5 MeV/u, which is designed for a hadron therapy linac injector. The voltage across the first and last gap in a drift tube linac tends to drop from a typical uniform voltage distribution along the inner cells. [...]

Analytic derivative of orbit response matrix and dispersion with thick error sources and thick steerers implemented in python
/ Franchi, Andrea (ESRF, Grenoble) ; Liuzzo, Simone (ESRF, Grenoble) ; Martí, Zeus (ESRF, Grenoble)
While large circular colliders rely upon analysis of turn-by-turn beam trajectory data to infer and correct magnetic lattice imperfection and beam optics parameters, historically storage-ring based light sources have been exploiting orbit distortion, via the orbit response matrix. However, even large collider usually benefit of the orbit analysis during the design phase, in order to evaluate and define tolerances, correction layouts and expected performances. [...]
