[Halld-pid-upgrade] Talk from Jerry

[Shepherd, Matthew]

Hi all,

I've uploaded a talk that Jerry sent me that he gave at Argonne a few weeks ago on development of DIRC detectors.  It has many interesting photos and potentially useful plots.  As we transition from concept to working detector, this may be a useful reference.

It is here:
