# Announcements
#* New graduate student at Regina, Giovanni Alcocer, will be working on reconstruction effort and then analysis. Learning C++ and ROOT
# [[GlueX-Collaboration-Oct-2013|October Collaboration Meeting]]
#* May not need the third slot, offer it to Curtis.
# Action Items
# Monitoring
#* Plexiglass sheets are in.
#* Documentation is being collected (primarily from Athens) for the sanding and painting. John hopes to start mounting next week.
#* NIM paper (Zisis) has been submitted. Preliminary communications with editors are taking place.
# FCAL
#* Cabling complete!
#* The cabling is very nice and neat. Will ease access during maintenance. Provide an example to the rest of the detectors.
# BCAL
## Reassembly of modules used in ESB during tests
##* The modules (#1's), which were used for testing modules in the ESB were opened and refurbished for use the the actual detector.
##* Traces of liquid were found inside the module on the silicon pad used for extracting heat off the electronics board.
##* Initial thoughts were that this was condensation, but closer inspection showed the liquid was somewhat oily. It could be anti-freeze from the cooling system.
##* Traces of the liquid were taken from the silicon pad and EH&S has sent them out for evaluation. The amount of liquid might not be sufficient for evaluation. No report yet.
##* We want to make sure the system is kept under nitrogen flow.
## Moved BCAL into solenoid! 
##* Photos [http://gluex.phys.uregina.ca/content/photo/downstream-view-bcal-after-installation Downstream View], [http://gluex.phys.uregina.ca/content/photo/upstream-view-bcal-after-installation Upstream View], [http://gluex.phys.uregina.ca/content/photo/closeup-upstream-view-bcal-after-installation-four-support-strips-are-visible Closeup Upstream View]
##* Removed readout assemblies from both sides of six modules (33-37 and 41) for inspection
##* All electronics dry. No visible damage
##* Assemblies on the rail pads very tight. Need to remove inside plate on some in order to take them off. This should be standard procedure.
##* Downstream no visible anomalies. 
##* Upstream, boundary between module 41 and 40 showed a thicker dark band at interface (about 1-2 fibers instead of 0.5-1), but did not appear to be due to insertion of the module. Seems consistent with Regina archival photo [http://kronos.phys.uregina.ca/~zisis/travellers/Mod41/photos/Mod41R.jpg End 2 Image].
##* Conclude: no damage found due to insertion of the BCAL into the solenoid.
## Cosmics Analysis [https://halldweb.jlab.org/doc-private/DocDB/ShowDocument?docid=2292 | Shaun K.]
##* Fits using two Gaussians. "Mean" parameter indicates the place where the two Gaussians are joined (it is not the mean of the distribution).
##* Elton: Expectations are based on beam test data, so they probably effectively include the acceptance for the light guides of the inner layer
##* Many of the runs with insufficient events has been traced to the use of root files that did not contain the full data set. These will be rerun.
# Reconstruction and Simulation: [[BCAL Reconstruction Meeting 2013-09-17]]
#* Giovanni has joined the effort. George has been stalled due to the closure of universities. Will has investigated the reason for slow daily reconstruction of clusters and implemented a fix. He will give a talk at the collaboration meeting.
