you anticipate submitting a proposal, get started.
iii)	CHL2: Pump down, good news and bad news
(1)	Got to 2K
(2)	Couldn?t stabilize
iv)	There?s beam in the injector (30 microAmps, 500 keV)
v)	U-tube incident has resulted in the development of an OSP. 
It?s being reviewed for Physics (Chris Keith)
vi)	The ?Priorities PAC? is tentatively scheduled for mid-
May 2014
vii)	Software review:
(1)	Ole Hansen: External review in 2 weeks  reviewing 
software developments for 12 GeV
viii)	Space:
(1)	Testlab High Bay is set up (naturally there is 
some flexibility)
(2)	Physics Chalet is a work in progress
(3)	Next in line are EEL 125 and TEDF High Bay
ix)	Expect an inventory of electronics soon. Will focus on 
pmt?s, calorimeter blocks, and electronics modules. It 
isn?t clear how thorough. Want to assess what we have, 
where it is, what can be shared, and what can be thrown 
out.
x)	Chris Cuevas reported on Electronics developments (long 
impressive talk). Some topics:
(1)	Beam Raster monitoring module is ready for testing
(2)	New database being started (PEER) to track 
electronics (service record, repairs, etc.)
(3)	Lots of new stuff
b)	SBS review:
i)	John LeRose:
(1)	Went well, we got at least an A
(2)	Scintillator coordinate detector was well received
(3)	Have a to do list
c)	SOLID:

b)	SBS:
i)	Working on assembly hardware
ii)	Working on support structure
iii)	Received best and final offers on the magnet coils
c)	APEX septum going into drawing system
d)	PREX: Al Gavalya has given feedback on collimators
e)	Continuing on Cherenkov detector designs
f)	Attended Hall dump meeting:
i)	We need to define what things can be done in January
ii)	We also need to define what we need
g)	Tritium vent system work continues
3)	Ed Folts
a)	Compton is finished for now (will revisit after the optics 
are installed)
b)	Picked up the raster beam tubes today (11/12)
c)	Cryo is ready for clean up
d)	Documenting what?s been changed or repaired
e)	Making a beamline punch list
4)	Charles Hightower
