# Announcements
# [[FCAL Fabrication Readiness Review]]\
#* Jim will send us the form that they use to review projects
#* Bruce (Lenzer) asked if they could visit subcontractors
#* Special questions regardind welding of Fcal frame and whether shops
were code qualilfied
#* Elton mentioned that following the Readiness Review there will be an
approvals for electronics and the support structure, which may be the time
that shop qualifications will be verified.
#* Ryan will have the John/Matt post the most up-to-date documents in
advance of the Review
# Review of Action Items
#* Will to remind Inaki to send drawings of light guides being produced.
# Calibration/Monitoring (Zisis)
# FCAL
## Construction status
## To shashlyk or not to shashlyk.
##* Radiation damage studies of the Pb glass will likely be repeated at
IUCF with a current monitor to check the normalization of doses to the
detectors.
# BCAL
## Construction Status
##* Module 11 60% complete, Module 12 65% complete
##* Fiber shipment #13 under test for attenuation lengths
##* Npe measurements postponed to allow DAQ to be used for test acceptance
for gaps between sensor and light guide
##* Cosmic ray measurements will start soon
##* Machining of 5-8 is 70% complete at Ross machining
## Fibre QA: [[Media:Shipment11_Npe.png]] and [[Media:Shipment12_Npe.png]]
##* Elton noted that exchanges with Kuraray regarding anomalous Kuraray
measurements of attenuation for 11 and 12 seem to have found a problem
with the Kuraray data. This is being tracked down.
# Simulations
#* Planing for simulations to calculate the energy deposited in cosmic ray
setup for a given trigger and geometry.
# USM update
#* 3 light guides completed
#* chiller arrived today
#* Serguei took 2 light guides to CERN to mail to Athens.
#* MOU is getting signatures today.
