How complex is the conversion of Oracle DB to XAL lattice? Does the db contain enough to emit a lattice
...
- ? Mark Woodley warns that there are probbaly many things necessary in the XAL lattice which need not be in the DB (marker points), and many things in the DB which should not be in the lattice. This latter class includes things like dummy BPMs, so not simply the case that everything of a given class should be in the lattice. People change the z of things in the DB. May be a good idea to have a "Skeleton" XAL file (maybe processed by xsl/php).

Which XAL applications allow one to update the EPICs magnet k-values after a successful model run?- Does XAL really not model acceleration? If not how is it useful for SNS?
- Verify that XAL does not model a plane coupled system.
- Does XAL offer matrix manipulation, linear algebra and fitting adequate for the LCLS? Ans: yes, uses JAMA.
- How long does XAL take to parse an XAL beamline? It has to build a DOM tree, which can't be negligible. Since that is a requirement of every XAL application at initialization its an important performance bottleneck.
How many beamline descriptions should there be?Anchor q_numbeamlines q_numbeamlines - What is the canonical list of XAL physics apps?
- Does LCLS need SVD based orbit minimization? Is there an orbit minimization in XAL?
