[Live version](https://www.ncnr.nist.gov/resources/activation/)

Installation
============

The activation web frontend is in the activation subdirectory and the cgi
backend is in cgi-bin. Update the server with something like:

sudo cp -rp activation/* /var/www/resources/activation
sudo cp -p cgi-bin/nact.py /var/www/cgi-bin

The web page uses the date of activate/index.html to show the last
modification date on the program, so be sure to preserve attributes in copy.

Be sure the web server is configured to use python 3, with the periodictable
package updated to the latest version:

sudo pip3 install periodictable --upgrade

Be sure that changes to the periodictable backend are noted at the end of the
help section in index.html in the repository. As well as informing users
of updates this will also set the last modification date on index.html.

Additional files in the repository:

* endf/* was used to generate the graphs of thermal resonances. It is not
needed unless you wish to update the graphs, for example, when new versions of
the endf database are released.

* server.py is used to run a test server for debugging the web application, or
showing potential new features to users. See the help inside the file for
details on running the server.

* cgi-bin/massfrac.py computes mass fractions for the elements in a compound. It
is not yet used by the web frontend.

* cgi-bin/hello.py is a minimal test script for python cgi.

/* TODO: show cool-off date.
The implementation below will confuse users since cool-off date is relative
to the time off beam rather than the current time. This is okay when the
"Decay" field is set for an existing sample, but the common case is to
estimate activation for a sample you are planning to put on the beam not
one that you have already measured and removed. We could tweak the interface
so that we only display the cool-off date when decay time is negative or
decay time is a time stamp, or we could just live with the confusion.
I'm going to punt on this for now.
