BASIC MODELLING ENVIRONMENT
This will proceed in 4 phases:
- Phase 0: For BC-1 commissioning, physicists will use the SLC online model system. DIMAD decks generated in the familiar way. The only addition will be to use AIDA's interface to the SLC model system for new (matlab) applications and ad-hoc analysis in matlab.
PRJ-ADDFILEMODELDATA: Add to the model data acquisition already in Aida, the ability to get QUAD, BEND etc data from SLC model output file.Anchor PRJ-ADDFILEMODELDATA PRJ-ADDFILEMODELDATA - Phase 1
PRJ-MADTWISSTODB: Put Mad model run results in the Oracle database. Both "design" and "extant" machine should be supported. Modelling the extant machine will be done by running the mad input through a filter, which will find the epics PV or slc db name associated with each device (via the "symbols" Oracle schema), and create an output file which can be run by Mad. The resulting Twiss and R-mat will then be loaded into Oracle.Anchor PRJ-MADTWISSINDB PRJ-MADTWISSINDB
PRJ-BDESTOKMOD: We will need a "bdes-to-kmod"Anchor PRJ-BDESTOKMOD PRJ-BDESTOKMOD

...
- If
...
- after
...
- analysis
...
- that
...
- seems
...
- hard,
...
- we
...
- should
...
- consider
...
- jumping
...
- straight
...
- to
...
- phase
...
- 2,
...
- since
...
- XAL's
...
- tracking
...
- will
...
- acquire
...
- klystron
...
- readings
...
- and
...
- make
...
- the
...
- conversion
...
- directly,
...
- at

- the
...
- time

- of

- so
...
- in

- this

...
- it
...
- would
...
- be
...
- easier
...
- than

- implementing

...
- model.
...
- Phase
...
- 2
...
- will
...

...
- involve
...
- adapting
...
- XAL
...
- for
...
- the
...
- LCLS
...
- beamline
...
- requirements

- (acceleration,
...
