How will we provide these Applications?

SLC Applications, via the SLC-aware IOCs

XALDeveloped by and proven successful at SNS

Java based; platform independent

Has a future with the EPICS community

Includes an online model

Includes many applications already developed at SNS

SLC Applications Available to LCLSSLC-aware IOC provides BPM data, data from other gated acquisition devices, and magnet control to the SLC Control System

An online model of LCLS in the SLC system will provide model data

Injector, linac, BSY only for now

Therefore, the following SCP applications will work for LCLS:

Orbit applicationsOrbit display

Orbit fitting

Orbit correction

Bump calculations

Power steering

Energy Management

Support softwareBuffered acquisition

Correlation plots

Multiknob facility

SLC CA server (CAMAC device readback)

Configs (configuration management)

Applications not provided by SLC

Bunch Length Measurements, and

Emittance and Energy Spread ApplicationsThe slc-aware portion of the IOC will not perform wire scans, does not control the bunch length measurement devices (OTRs, YAGs, RF deflector), nor does it provide images to the SLC system.

These measurements will be done by the IOCs in EPICS only.

The control, readback, data PVs are accessible by Channel Access.

Control of CAMAC devices is not available through Channel Access.

Concerns and solutions

Bunch Length Measurement, Energy Spread, Emittance applications not available via SLC

Fully develop these applications in XAL; start with existing SNS applications

Backup: Develop in Matlab for commissioning. Aida provides SLC model data, Channel access or Aida gets IOC measurements via PVs.

Energy Management

Energy management will not be needed until commissioning beyond BC1 is started

XAL Issues

Configuring the online model to work for LCLS

Adjusting XAL’s SMF device classes to match LCLS devices; add new devices

SNS is a smaller system; we must be mindful of difficulties with ‘scaling up’ for LCLSLCLS – we want more calculations performed by IOCs; data reduction

LCLS - we want to add more status checking

LCLS – the online model is much larger, more time required to run model

network traffic with Channel Access and files required by XAL apps.

LCLS will have more users running apps

CAMAC device control is not available from the SLC

Slc-aware IOCs will not control CAMAC devices; MCC CA Server is read-only; no control

Magnet control via Aida is under development now; or Change CA Server to read / write
