1 LHC Systems Providing Post-Mortem Data
Stephen Jackson Diogo Miguel Louro Alves Manuel Gonzalez Berges Enrico Bravin Marek Gasior Lars Jensen Ana Guerrero Ollacarizqueta Stephane Bart Pedersen Athanasios Topaloudis BI-TB 16/5/2019

2 Introduction (recap) Request from LMC and Evian for a “postmortem button” For any reason at any time, be able to record all data usually recorded in postmortem. There should be a way to trigger this from the CCC, or from timing event. Are there drawbacks (acquisition dead-time, limited storage)? The idea is to provide a list of what is easy/difficult, free/expensive to the management Example of use cases: 10 Hz oscillations (BPMs, diamond BLMs, BLMs) What happens at the beginning of the ramp Storing of ADT kick signals (not yet in postmortem) Identifying PM-like LHC data available from BI systems – BITB 16/5/2019

3 Introduction Task Identify LHC data available from BI systems With the view to acquiring from an on-demand trigger (MTG or soft) Issued by an LHC Operator or another intelligent source Only a few systems with interesting data at the TxT level So extended this presentation to include lower resolution data as well Identifying PM-like LHC data available from BI systems – BITB 16/5/2019

29 A Comment “The data is already in logging so not interesting”
Is there not an interest to identify a time of interest and package the same data as an event? The could be used as input to future machine learning ? BRAN, BSRT, … Identifying PM-like LHC data available from BI systems – BITB 16/5/2019

30 Possible New Data for Run 3
Orbit Feedback system 25 Hz BPM data and status Full frequency BBQ tunes (from all systems) COD+QUAD deflection / status + current requests As much history as you can consume BLM 100 Hz data Already used in several cases (collimation feedback, loss-maps, …) Create a new Capture type (called CAPTURE) Return all 43’690 80us samples Covering seconds STUDY currently covers seconds With new f/w, MBLT means readout will be several times faster BBQ Raw data for 10s of seconds on new MENA25 CPU?
