Rachel physical detector files

Several physical detectors (crystal types, not laboratory positions) can be defined by reading a text file of the following format.  

(See also the [[Rachel_format_detector_array_files|physical detector format]] for defining detector positions in the laboratory.  This is useful for defining and sharing the definitions of large detector arrays.)

This file can be read by selecting option ip from the Tools button menu.

The user-readable text file format is as follows:

<pre>
somecrystal
description Some type of Ge crystal
distance 20
outer_radius 4
inner_radius .4
length 9

someother
description some other type of Ge crystal
distance 30
outer_radius 3
inner_radius .3
length 10
