26. Greg White, Stanford Linear Accelerator Center, 2007 “Correlation Plots” * Steps any controllable thing, reads any, up to 160, readable values * Beam Synchronous - knows what to do * Total integration - eg step ring frequency, do orbit fit, read fit params * Includes plotting, fitting, optimization (eg implements quad scan)

27. Greg White, Stanford Linear Accelerator Center, 2007 History/Archive Data Chart Types: stripchart, Overlay, A vs B (interpolated), expressions in A, B and C Linear and Log axes Auto or manual scaling axes

45. Greg White, Stanford Linear Accelerator Center, 2007 Matlab java lessons datenum() converts time format data to plotable floats datetick tells current plot() to scribe axis with date/time textual date/time to float conversion is very costly ( soln. use say unix time rather than text ) Put java VM options in Matlab secret file java.opt.

46. Greg White, Stanford Linear Accelerator Center, 2007 Aida CORBA Performance Double: 1 or 2 ms, sometimes more Nd Vector DaValue: < 10 ms, Median 3 ms, sometimes more. Eg History, BPM, model Linear up to tested 4MBytes

51. Greg White, Stanford Linear Accelerator Center, 2007 What Did we Do Wrong - Bob Dalesio’s Slide Underestimated XAL integration (modelled elements, SMF layer, database integration) Underestimated db persistence Underestimated Eclipse questions –IDE RCP or our own Product –Building in a production environment –Distribution SWT <> Swing : Eclipse <> XAL Matlab pragmatism not accepted by everyone.

52. Greg White, Stanford Linear Accelerator Center, 2007 Questions - please talk to us! Macros (automatic script recording) over different hosts, OS? X11 only common factor! Headless, production, build of Eclipse? 3D visualization for accelerator physics? Impact/Parmela -> Elegant -> Genesis/Ginger
