The Distributed Oscilloscope: A Large-Scale Fully Synchronised Data Acquisition System Over White Rabbit / Lampridis, Dimitrios (CERN) ; Gingold, Tristan (CERN) ; Malczak, Milosz (CERN ; Warsaw U.) ; Vaga, Federico (CERN) ; Włostowski, Tomasz (CERN) ; Wujek, Adam (CERN)
A common need in large scientific experiments is the ability to monitor by means of simultaneous data acquisition across the whole installation. Data is acquired as a result of triggers which may either come from external sources, or from internal triggering of one of the acquisition nodes. [...]

Renovation of the Trigger Distribution in CERN’s Open Analogue Signal Information System Using White Rabbit / Lampridis, Dimitrios (CERN) ; Gingold, Tristan (CERN) ; Michalik, David (CERN ; Aalborg U.) ; Poscia, Aurelien (CERN) ; Serans, Miguel (CERN) ; Shukla, Mamta (CERN) ; Pereira da Silva, Tiago (CERN)
The Open Analogue Signal Information System (OASIS) acts as a distributed oscilloscope system that acquires signals from devices across the CERN accelerator complex and displays them in a convenient, graphical way. Today, the OASIS installation counts over 500 multiplexed digitisers, capable of digitising more than 5000 analogue signals and offers a selection of more than 250 triggers for the acquisitions. [...]

SAMbuCa: Sensors Acquisition and Motion Control Framework at CERN / Masi, Alessandro (CERN) ; Andreassen, Odd (CERN) ; Arruat, Michel (CERN) ; Danzeca, Salvatore (CERN) ; Di Castro, Mario (CERN) ; Donzé, Mathieu (CERN) ; Fargier, Sylvain (CERN) ; Ferraro, Rudy (CERN) ; Gulin, Marco (CERN) ; Kozsar, Ioan (CERN) et al.
Motion control systems at CERN often have challenging requirements, such as high precision in extremely radioactive environments with millisecond synchronization. These demanding specifications are particularly relevant for Beam Intercepting Devices (BIDs) such as the collimators of the Large Hadron Collider (LHC). [...]

Trigger and RF Distribution Using White Rabbit / Włostowski, Tomasz (CERN) ; Daniluk, Grzegorz (CERN) ; Lipinski, Maciej (CERN) ; Serrano, Javier (CERN) ; Vaga, Federico (Pavia U.)
White Rabbit is an extension of Ethernet which allows remote synchronization of nodes with jitters of around 10ps. The technology can be used for a variety of purposes. [...]

Managing your timing system as a standard Ethernet network / Wujek, Adam (CERN) ; Daniluk, Grzegorz (CERN) ; Lipinski, Maciej (CERN) ; Rubini, Alessandro (GNUDD, Pavia)
White Rabbit (WR) is an extension of Ethernet which allows deterministic data delivery and remote synchronization of nodes with accuracies below 1 nanosecond and jitter better than 10 ps. Because WR is Ethernet, a WR-based timing system can benefit from all standard network protocols and tools available in the Ethernet ecosystem. [...]

Processing High-Bandwidth Bunch-by-Bunch Observation Data from the RF and Transverse Damper Systems of the LHC / Ojeda Sandonís, Miguel (CERN) ; Baudrenghien, Philippe (CERN) ; Butterworth, Andrew (CERN) ; Galindo, Javier (CERN) ; Höfle, Wolfgang (CERN) ; Levens, Thomas (CERN) ; Molendijk, John (CERN) ; Vaga, Federico (Pavia U.) ; Valuch, Daniel (CERN)
The radiofrequency and transverse damper feedback systems of the Large Hadron Collider digitize beam phase and position measurements at the bunch repetition rate of 40 MHz. Embedded memory buffers allow a few milliseconds of full rate bunch-by-bunch data to be retrieved over the VME bus for diagnostic purposes, but experience during LHC Run I has shown that for beam studies much longer data records are desirable. [...]
