25/01/2001 PS days - Evian Application software: status & trends  Automatic Beam Steering and Shaping (ABS)  New Java application environment  Linux deployment  Consoles & servers  Network & communications  Front-end I/O Controls infrastructure: tomorrow by tomorrow by Franck di Maio

25/01/2001 PS days - Evian ABS Communication architecture OPTICS DATABASE Layout, optics, correctors, monitors Corrector magnets CORRECTION MICADO Mathematica algorithm MEASUREMENT

25/01/2001 PS days - Evian Automated Beam Steering & Shaping  Key achievements 2000 Review of generic correction program Version 1. (1999) considered by operators as MD tool Version 2. (2000) in operation. Proved to be satisfactory. Removal of design-inherent limitation Problem 1999: correction of coherent oscillations at PS injection diverged when actual tune was different from model tune Cure 2000: “universal” tune defined as model

25/01/2001 PS days - Evian ABS Communication Architecture

25/01/2001 PS days - Evian ABS Present status Operational corrections  PSB LIN2 to PSB steering (individual or global) PSB to PS steering (individual or global)  CPS Closed orbit at low energy Injection coherent oscillations (fully PPM) Injection bump oscillation (specialist) TT2 (PS) steering for all particles & energies & optics

25/01/2001 PS days - Evian ABS Objectives 2001  New corrections Global line TT2+TT10 steering (PS + SL devices) FTN steering for TOF beam CTF3 corrections: to be clearly defined  Architecture consolidation Java interface for ABS generic program Link between Optics & CO databases Automatic update of response matrices from database

25/01/2001 PS days - Evian ABS Objectives 2001 (cont’d)  Studies [A.Jansson PS/OP] PS injection matching using Q pickup Effectiveness of existing correction schemes Collaboration with Y-C.Chao (JLAB visitor) Verification of adequacy of correctors w.r.t. monitors “Intelligent” ABS program On-line construction of measured matrix Verification of the machine model by confronting measured and theoretical matrices.

25/01/2001 PS days - Evian New Java application environment  PS Java history 1998-mid99: performance evaluation + eqpt access June 99: Java activity launched  Motivations for Java Powerful language (Object-oriented, industrial tools) Platform independent=> possible sharing of code + control applications with SL/CO Attractive application development environment

25/01/2001 PS days - Evian New Java application environment  Key features of the new environment Transparent integration in the operator desktop Cohabitation Java & C programs Very close collaboration with OP developers for User Requirements specification + coding New concepts are introduced: data abstraction, acquisition coherency toolkit of reusable components Contact people: R.Hoh + M.Pace

25/01/2001 PS days - Evian New Java application environment  Current status Java = key product for new developments 13 under development 5 operational in 2000 Large involvement & interest from CO + OP + BD Weak point: environment is NOT yet stable  Environment’s evolution force applications to re-adapt Significant effort devoted to support + follow-up of developers  First objective Application interface stabilization

25/01/2001 PS days - Evian New Java application environment  Architecture

25/01/2001 PS days - Evian Linux deployment in the PS control system  Migration from IBM WS to PC/Linux  Aim Replacement of ALL IBM WS by PC/Linux control room consoles dedicated servers (DSC boot, passerelle)  Motivations for PC/Linux open source + portable + Unix software centralized IT support for Hardware + Linux cheap CERN-standard hardware platform

25/01/2001 PS days - Evian Linux deployment (cont’d)  1999 Migration evaluation tests. Librairies porting.  2000 Application porting under Linux. Tests on 2 MCR consoles for control of Lin2, PSB, PS  2001 Ctrl rooms: all consoles Linux-equipped (except LPI) Offices: dual-boot Windows-Linux proposed as standard configuration

25/01/2001 PS days - Evian Linux deployment (cont’d)  Porting status globally 80% of all existing applications: ported + validated by operators Reported problems from tests (end 2000): corrected  Short-term objectives Validation of ported applications for AD at startup 2001 Porting of Oracle Forms (used by CO people) Contact people: N.de Metz Noblat +J-M.Elyn
