AGENDA TTO follow up Run 11 -12 Goals Efficiency TTO FOLLOW UP P - PowerPoint PPT Presentation

AGENDA • TTO follow up • Run 11 -12 Goals • Efficiency

TTO FOLLOW UP • P . Krejcik wrote a synopsis of the Twin Bunch TTO project. • I started a TTO website (with a link to it from the Performance Program site) https://portal.slac.stanford.edu/sites/lclscore_public/tto/SitePages/Home.aspx

GOALS FOR NEXT RUN • Capability goals • Stability goals • Still missing Quality, Reproducibility, and Photon

EFFICIENCY 1/21/16

CONTROL ROOM REPORT Efficiency 1. operators doing work outside of daily operation - need to add management (working on that) mainly using project driven priorities, who are the customers? Hardware : priority is very roughly in order of list 1. Motion control is really painful except undulator 2. Laser cathode profile reproducibility 3. Laser motion control system is unreliable: steering and feedbacks, hysteresis, home is lost, resolution is poor for needs 4. Ability to recover from klystron cycles: feedback go wild, 6x6 is dumb (continued)

5. Klystron reliability / trip rate 6. Modulator upgrade fallout 7. Weak steering software: LTU feedback and steering, jitter, dispersion correction is lost 8. LLRF is not too bad according to Stanek - failure modes are difficult to detect 9. Timing system is ok: laser timing / phase timing; some new improvement is well liked: Frisch and Justin 10. Dispersion correction is poor. routines don’t converge and don’t cover many areas of the beamline 11. Lutman setups are too hard 12. Need more one button push stuff 13. Flow charts for special setups would be helpful 14. Changing matrices when changing energies should be automatic: no hooks for model 15. MPS just trips instead of rate recovery, some project is going but it taking years 16. Phase error masked by feedback corrections

WHAT CAN WE DO • Assign one LFD person to each item and ask them to find out what the underlying issue is and what solutions are possible.
