NSRL Data Library for Run 07B

This is the data repository for transferring data files out of NSRL.  It is organized by Run, Ion Species, Energy and Date.

These file contain the ADC values for the silicon stack, plus a selection of either a BGO crystal or an Elgin Counter.  The event record looks llike this for files Cary_1 through Cary_9A:

In the middle of run Cary_9, starting with run Cary_9B the event record format changed to just 10 words per event.  As listed below.

All files are ascii, approximately 3 MBytes in length.  Runs Cary_1 through Cary_8 have some synchronization problems, with event records occasionally getting out of step.  This problem did not appear after Run Cary_9.
