3d detectors

[Ankner, John]

Kristian,
     I modified your PSD_monitor routine to handle time-of-flight data
(called PSDTOF_monitor.comp).  The new detector generates data in x, y, and
t and I find I now have a major file-size problem.  For example, a 140×140
PSD_monitor generates about a 150 kB file.  If we divide 16.7 msec (1/60 for
the SNS source) into 10 mu-sec bins, we need 1670×150 kB or several hundred
MB.  These files are quite sparse, so there should be great gains to be made
via data compression.  In addition, the ideal way to view this data would be
by looking at x-y plots over a specified range of time channels.  This
viewing would best be done interactively.  In other words, import the entire
data set into a viewer to which one can specify a range of time channels.
My impression is that Nexus can help with both the compression and the
viewing.  Do you have any plans for generating Nexus files?  I will look
into this, but I suspect you are the most-qualified person for the job.

P.S. Is the source code for the DETECTOR_OUT_2D macro available?
