2 Intro q About COSY q Orbit correction based on ORM q Implementation at COSY q Results and conclusions
3 COSY (FZJ) q Cooler Synchrotron q Forschungszentrum Jülich q Polarized and non polarized beams q Beam cooling q Internal or external target q Preparations for EDM measurements
4 Orbit control based on ORM q
5 Orbit control based on ORM q
6 ORM and Bump Creation q Measured ORM empirically q Model -> ORM with a python script q Data from MAD-> bump creation q Bump creation confirms that model is realistic
7 COSY Control System q Custom CPU with Motorola processors q Ethernet based timing on 10 Megabit non switched network q Non distributed q Tcl/Tk GUIs, TCP
8 Control system design
9 COSY cycle operation
10 COSY cycle operation + OC
11 Full orbit correction state machine
12 Orbit correction GUI
13 Creation of a vertical bump
14 Correcting a vertical bump
15 Correction to zero over multiple cycles
16 Solving possible bottlenecks
17 Conclusions q COSY is an interesting machine with a great team q Implemented orbit correction in EPICS with virtually no hardware changes and minimal downtime q Introduced distributed ACS q Really interesting project
