Hi,

I've been tasked with developing a new correlation application to replace
the storied Correlation Plots from the old SLC control system.

My intent was to develop an eclipse-based java app to accomplish this.

However, Earnest Williams and Stephanie Allison suggested that I should look
into sscan and SynApps.

While these tools do seem feature-rich, they don't provide all of the things
that we want.  So my questions are

(1) can they provide the functionality we want?
(2) do we need the functionality that we think we want?

The main issues:

(a) user-extensibility
We want our physicists and other users easily to define steps, measures, and
step functions using tools they are familiar with, like Matlab.

(b) beam synchronous data acquisition
We need to use our specially developed beam synchronous data acquisition
system to acquire pulse-synchronous data.  How can the sscan record support
this?

(c) concurrent use
Can one perform multiple scans concurrently with the sscan record, or must
one pre-create multiple instances of the record to achieve such?

(d) data types
Can this system retrieve data of types other than simple numbers?

(e) design philosophy
Is it a good idea to put this sort of functionality in an IOC?  It seems
sort of limiting to me.  Why do it?  Is it a matter of using the tools at
hand, or are there more compelling reasons that I don't see, being mostly
unfamiliar with IOC level applications?

Thanks for your comments,

Chris
