First Beam
LCLS commissioned a new injector with beam
AND commissioned a new Control System

Overview
This presentation summarizes which control system components are currently working for the injector commissioning phaseScreen shots from EPICS show functionality of each systemData from the Elog is shown to illustrate acquisitionComments on what works and what doesn’t are includedSummary includes lessons learned and what still needs to be done

MPS- working with SLC processor and timing
- ion chambers do trip beam
- several MPS inputs (limit switches on obstructions) not available yet

Conventional facilities- interfaced to EPICS controls- gun LCW temp feedback working ok at 30 Hz
- need to add alarm interface for temperatures, flows etc.

Asynchronous Beam Acquisition via SCPe.g. Gun charge vs. laser power
Measured on the SCP Correlation Plot
But some people still plotting data offline

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

Summary and lessons learned
Remarkable commissioning achievement for the control systemControls commissioning time was squeezed
How do we ask for more?
Planned BC2–linac installation is tight Improve liaison with mechanical engineeringWe 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!
