II.Verify electron beam is on gun axis:
Actuators: laser beam steering mirrors
Actuators:Gun rf amplitude
SOL1 current
Detectors:BPM2
Detectors: BPM2 X and Y position

Virtual cathode (X and Y position)
Virtual cathode (X and Y position)
a. Launch electron beam at 30 degrees relative
to zero-crossing phase
b. Measure beam X and Y position on BPM2
vs. SOL1 current
c. Move laser beam on cathode until there is no
electron beam motion at BPM2.

a. After completing I. above, vary
amplitude of gun rf and measure
electron beam X and Y position with
BPM2.
b. Plot BPM2 vs. RF gun amplitude
to determine steering by gun rf fields.

Applications provided by the SCP
Correlation Plots
Buffered Acquisition
Orbit Applications
Multiknob
On-line model
Configuration management
The slc-aware IOC allows the SLC to control and readback
all new magnets, and provides beam synchronous data to
Buffered Acquisition and Correlation Plots from:
BPMs, BLEN, PMTs, LLRF, Faraday Cups, Toroids, some Laser devices

Applications provided in MATLAB
Image Management
Bunch Length Measurement
Emittance and Energy Application
These applications are developed in MATLAB because they
require an interface to wires and screens (OTRs / YAGs).
The slc-aware IOC does not support the wire and screen
devices; they are not available to the SLC applications.

Feedback Prototypes in MATLAB
Goals for MATLAB prototypes
To evaluate feedback algorithms for use during
commissioning
We hope for a better than 1Hz feedback rate using
MATLAB
To learn more about the LCLS feedback requirements in
order to design and implement an IOC based fast
feedback subsystem in 2007.
