1. Progress report on multi-OTR fabrication and schedule IFIC-SLAC  Design and Hardware fabrication  Realistic Optics and Beam Dynamics simulations  Controls and Software analysis Outline

2. Design and Hardware Fabrication Design and Hardware Fabrication  Finalize design shortening beam tubes until 300 mm overall length  Purchase movers  V/H movers,  Pneumatic target inserter  Focus adjustment  X/Y camera positioner  Purchase hardware control  Two 8 channels stepper motor driver  12 channels digital control target actuator  12 ADC channels for read back of linear pots  Purchase Optics  Camera  C-mount optics tubes 150 mm for each OTR  Mitutoyo 10X long working distance microcope  90º C-mount mirror

3. Design and Hardware Fabrication Design and Hardware Fabrication  OTR main fabrication  OTR body and optical windows parts  Fabricate and weld flanges on tubes and tubes to OTR body  Fabricate and weld bellows and flanges  Fabricate OTR moving system adaptors

4. 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

5. 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

6. 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 tracking  Piggyback on the software planned for multi-wire system

7. 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
