Linac & BC2 Controls Installation

Detailed plans were in place Feb-March 2007The scope includes

Adding new magnets including pulsed horizontal pulsed horizontal dipole magnetdipole magnetAdding BPM, x-collimator, OTR screenExtending the new timing systemSafety systems (MPS, BCS)

BC2 installation, similar scope to BC1Very little engineering developmentThe biggest challenge has been meeting the schedule

Controls for LTU, Undulator, E-dump

Identification of cable plant is nearing completion and documented in CAPTAR

We have developed electronics rack profiles for nearly all systems

We have an installation plan which is being integrated with the over all 2008 schedule

The challenge is coordination with other installations

Plans for the Next Six Months

Complete the BC2 installation and support the commissioning effort

Develop detailed plans for LTU, Undulator installation

Make major progress on the next generation high level applications software

LCLS FAC Review – October 200730

ConclusionsWe have been providing ongoing support for the injector controls

The commissioning experience and the collaboration with physicists have been very effective in refining the systems

BC2/Linac Controls installation is proceeding well and close to the original schedule

We are developing detailed controls installation plans for the remainder of the e- regions

With the exception of a few systems, we are over the engineering curve, and the remaining challenge is maintaining the schedule
