Slaughter Coordination, monitoring, analysis Controls Department T. Bolshakov, M. McCusker, K. Cahill, B. Hendricks, J. Patrick and others Infrastructure and applications Computing Division K. Genser, P. Lebrun, S. Panacek Analysis and applications

SDA- Jean Slaughter – Apr 5, 2004 – All experimenters’ Meeting3 Two Aspects of Shot Data Analysis Acquiring and archiving the data SDA - sequenced data acquisition - main source of information sequencer driven processes that collect a defined set of information from multiple sources at specific times during a “store”.. Data loggers Not “store” oriented Now has a backup node for permanent storage Analyzing the data Standard tables and plots built automatically Browsers – SDA Viewer Special purpose studies

SDA- Jean Slaughter – Apr 5, 2004 – All experimenters’ Meeting8Supertable One line per store Built automatically every store 130+ quantities of general interest Dates, time on helix, length of store, how store ended Luminosities, intensities, lifetimes, efficiencies, emittances at various steps in store Web Accessible – HTML, EXCEL analysis with plots, tables also on Web Standard source of performance data Dave McGinnis’ Plots

SDA- Jean Slaughter – Apr 5, 2004 – All experimenters’ Meeting10 Derived Tables- Bunch by Bunch Information Table per store – built automatically All 6 emittances Intensities Average and bunch by bunch information Use best algorithms to get physics quantities Not always available directly from front-end. Interactive plotting interface

SDA- Jean Slaughter – Apr 5, 2004 – All experimenters’ Meeting12 Store Checker Purpose Monitor instrumentation and DAQ Monitor accelerator performance – soon Checks SDA data for specified cases/sets Min < device value < max Min < ( difference in time of 2 devices ) < max Min < ( difference in value of 2 devices) < max Jobs run automatically every store “Standard” and “private” lists Results on WWW for “standard” list Lists on WWW Used to give email notification of initial luminosities

SDA- Jean Slaughter – Apr 5, 2004 – All experimenters’ Meeting13 Calculated Luminosity. (1) N = numbers of protons, anti-protons per bunch (10 9 ) B = number of bunches (36) f = revolution frequency (47.7 KHz) r r = relativistic factor, 1045 = interaction point (cm, assumed equal in x and y). H = hourglass factor, function of l, bunch length, * = transverse emittances
