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

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
