Key achievements 2000Key achievements 2000Review of generic correction program

Version 1. (1999) considered by operators as MD toolVersion 2. (2000) in operation. Proved to be

satisfactory.

Removal of design-inherent limitationProblem 1999: correction of coherent oscillations at PS

injection diverged when actual tune was different from model tune

Cure 2000: “universal” tune defined as model

New New JavaJava application environment application environment

PS Java historyPS Java history1998-mid99: performance evaluation + eqpt accessJune 99: Java activity launched

Motivations for JavaMotivations for JavaPowerful language (Object-oriented, industrial tools) Platform independent=> possible sharing of code

+ control applications with SL/COAttractive application development environment



Key features of the new environmentKey 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 coherencytoolkit of reusable components

Contact people: R.Hoh + M.PaceContact people: R.Hoh + M.Pace



Current statusCurrent statusJava = key product for new developments

13 under development 5 operational in 2000

Large involvement & interest from CO + OP + BDWeak point: environment is NOT yet stable

Environment’s evolution force applications to re-adapt Significant effort devoted to support + follow-up of developers

First objectiveFirst objectiveApplication interface stabilization
