XAL Work in More Detail

Due to tight schedule, hacked into XAL code directly for SMF, online model.Still need to add *Lots* of very LCLS-specific device/PV support, e.g. the “beam synchronous acquisition” PVs.Manually adding RF cavity “gaps” to XAL XML file.

XAL Setup

Besides the XAL XML file preparation, XAL setup is relatively easy

Following the “How-to” comes with the packageSet up a couple environment variablesGet source code, build JAR files(optional) Set up JCA

(optional) Choose JCA/JNI or JCA/CAJ in Java Preferences

(optional) Set up “default” accelerator(optional) Set up “default” database connectivity

Conclusion

Significant amount of work is for database -> XAL XML file setupExperience

if not using Eclipse, things get slightly easierXAL GUI frame can be used

So far, our difficulty is mainly from Eclipse, not XALBut, we only did in “quick-and-dirty” way
