Patrick Krejcik LCLS April 16-17, 2007 Breakout Session: Controls Controls Commissioning Experience

Patrick Krejcik LCLS April 16-17, 2007 First Beam LCLS commissioned a new injector with beam AND commissioned a new Control System

Patrick Krejcik LCLS April 16-17, 2007 Overview This presentation summarizes which control system components are currently working for the injector commissioning phase Screen shots from EPICS show functionality of each system Data from the Elog is shown to illustrate acquisition Comments on what works and what doesn’t are included Summary includes lessons learned and what still needs to be done

Patrick Krejcik LCLS April 16-17, 2007 Everything is accessible from this screen

Patrick Krejcik LCLS April 16-17, 2007 Beam line graphic used for most GUIs e.g. injector vacuum summary

Patrick Krejcik LCLS April 16-17, 2007 PPS Summary status displays

Patrick Krejcik LCLS April 16-17, 2007 BCS Summary status display: - Calibration of detectors not completed yet - SubBooster Interface timing “difficult”

Patrick Krejcik LCLS April 16-17, 2007 MPS - working with SLC processor and timing - ion chambers do trip beam - several MPS inputs (limit switches on obstructions) not available yet New optical fiber Loss monitor screen

Patrick Krejcik LCLS April 16-17, 2007 Conventional facilities - interfaced to EPICS controls - gun LCW temp feedback working ok at 30 Hz - need to add alarm interface for temperatures, flows etc.

Patrick Krejcik LCLS April 16-17, 2007 Timing System - see separate presentation by S. Allison - LCLS Event system and SLC Timing working in consort

Patrick Krejcik LCLS April 16-17, 2007 Laser Systems - Image Acquisition and Steering Feedback

Patrick Krejcik LCLS April 16-17, 2007 Magnet Controls

Patrick Krejcik LCLS April 16-17, 2007 Low Level RF Control

Patrick Krejcik LCLS April 16-17, 2007 Gun RF Feedback in Operation - closing the loop between PAD and PAC

Patrick Krejcik LCLS April 16-17, 2007 RF Phase Scans Data acquired with Matlab Data acquired with SCP Correlation Plot (diagnose a satellite peak from laser)

Patrick Krejcik LCLS April 16-17, 2007 Profile monitors - control and diagnostics through EDM screens

Patrick Krejcik LCLS April 16-17, 2007 Image acquisition with Matlab Gun spectrometer YAG Profile Monitor Screen Using physicist’s scripts up till now ImageManager package coming online now

Patrick Krejcik LCLS April 16-17, 2007 Beam Position Monitors - see separate presentation from S. Smith

Patrick Krejcik LCLS April 16-17, 2007 Asynchronous Beam Acquisition via SCP e.g. Gun charge vs. laser power Measured on the SCP Correlation Plot But some people still plotting data offline

Patrick Krejcik LCLS April 16-17, 2007 Beam Synchronous Acquisition is working through Matlab – example of orbit display - BSAP via the SCP coming next

Patrick Krejcik LCLS April 16-17, 2007 Motion control -BC1 chicane movers in use - next to be commissioned: wire scanners, collimators

Patrick Krejcik LCLS April 16-17, 2007 Generic Tools that are working SCP Configuration save and restore EPICS Channel Watcher Correlation plots Strip chart tools Archive Viewer Alarm handler Electronic logbook Matlab for higher level applications

Patrick Krejcik LCLS April 16-17, 2007 Strip Tool monitoring gun temperatures during RF trips

Patrick Krejcik LCLS April 16-17, 2007 Electronic logbook gives instant overview

Patrick Krejcik LCLS April 16-17, 2007 Control Room Conditions Still a Bit Cramped (first beam to end of BC1!) Reorganizing the control room layout Purchasing more workstations Injector commissioning involved 12 or more in the room, so its likely to increase as the linac and undulator systems are commissioned

Patrick Krejcik LCLS April 16-17, 2007 Summary and lessons learned Remarkable commissioning achievement for the control system Controls commissioning time was squeezed How do we ask for more? Planned BC2–linac installation is tight Improve liaison with mechanical engineering We are still learning how to handle large number of IOCs and the huge number of PVs e.g. Restoring after a reboot Large number of EDM displays can confuse operators at times (looking for a screen that may be already open) Controls group is a great TEAM!
