Re: rapid scans

[Brian Tieman <tieman@aps.anl.gov>]

We are in the preliminary stages of looking at detector driven 
acquisition.  That is, when the detector registers an event, read the 
current position values and time and store the event with all this info 
in a table that can be parsed into "cells" later on.  The positioners 
can then run at a constant speed.  If a longer "dwell" time is needed, 
one can scan the area multiple times.

There is a heavy burden on the software, but at this early stage, the 
hardware looks manageable enough.
