==Construction==
 
−
* Ian Winger sent Chuck a 3-D drawing of the split light guides.
 
−
* Paul will be busy with his DOE annual for the next week or so.
 
−
* Three more light guides have been made from the UVT material.
 
−
** These will be compared to non-UVT versions.
 
−
* FSU Physics machine shop playing with procedure for fabrication.
 
−
** They are getting good finishes with the new bit.
 
−
* One light guide, was sent to Polymer Plastics for vapor polishing. It was due back this week.
 
−
* Paul has talked to folks at Eljen about how they do polishing
 
−
** Although vapor polishing will give good results, it is likely not better than hand polishing.
 
−
** Paul purchased got some polishing compounds to try.
 
−
** The Physics Department bought a new buffing station suitable for light guides.
 
−
* No testing with the new light guides has been done yet.
 
−
* Paul will send Chuck the dimenions of the steel tube.

==Time-Walk Correction Tests==

−
Sasha tried out the technique that Elton described in a [http://argus.phys.uregina.ca/cgi-bin/private/DocDB/ShowDocument?docid=1719 recent note]. See [https://halldweb1.jlab.org/talks/2011-3Q/Time-walk%20corrections.html his plots] for details. Cosmic data taken with prototype counters show some of the general features expected, but there is a non-Laudau distributed background in the sample that complicates the fits.
