Realistic Optics and Beam Dynamics Simulation Realistic Optics and Beam Dynamics Simulation

Study of the possible locations space, better optics conditions Tracking studies the model should be completed adding all possible machine imperfections Modelisation of the OTR measurements Comparison with the multi-wire scanner measurements

Controls and Software Analysis Controls and Software Analysis

Control needs Low-levels drivers for:

CCD frame grabber, V/H movers, lens focus movers, OTR insertion actuator

EPICS drivers and Data Base choose hardware controls with EPCIS module support High-level interface EDM, Flight Simulator… Hardware protection for:

Target damage CCD radiation sensitive

Controls and Software Analysis Controls and Software Analysis Software analysis

Can be done in any scripting/programming environment supported by EPICS CA (C, C++, Perl, Python, Matlab, TCL…)

Output processed data to EPICS Process Variables when done Scripts/code should also be controlled via PVs

2D Gaussian filter, taking CCD image and generating beam matrix data

Online Twiss/Emit calculations Upgrade FS EXT emittance minimisation application

Beam finder and tracker Track interpolated beam position in OTR target locations using adjacent BPMs for faster OTR insertion Intermittent target insertions to check trackingPiggyback on the software planned for multi-wire system

Conclusions Conclusions

The tasks has been identified

We are working on the schedule of the different phases:Design and Hardware fabrication (~4 months) Realistic Optics and Beam Dynamics simulations (~2 months) Controls and Software analysis (~4 months)

We could give a realistic schedule mid-September 2009
