== Agenda ==
Updates from Rakitha,
* Plastic Shielding Design Update - 3 [http://ace.phys.virginia.edu/HAPPEX/2942 elog-2942]
Updates from Lorenzo
* Septum pipe magnetic field implementation in PREX geant4 simulation [http://ace.phys.virginia.edu/HAPPEX/2937 elog 2937]
Present:<br/>
Rakitha, Dustin, Paul, Lorenzo, Nickie, Seamus, Guido, Juliette, KK and Kent

== Minutes ==
* Plastic shielding 
** Some concerns for putting plastic in the vacuum include,
*** Thermal damage : we are able to reduce the power down to about 3 W at 100 uA now and Lorenzo is planning to do a analysis to estimate the upper limit of the temperature due to this power for the plastic in vacuum.  
*** Out-gassing in vacuum 
*** Get more literature on this
* Magnetic Shielding
** If we can get TOSCA model from Paul Brindza, Juliette could optimize the magnetic shielding. We have never used TOSCA to do this before.
** We want to compare the fringe field with added 10 cm at the ends of septum pipe.	
** Then compare magnetic field on/off power in the hall.

== Misc.==
* From Last Meeting
**Beam parasitic studies

=== TO DO Lists ===
* Organizing a PREX Collaboration meeting (discussed in 02/6 and 02/13 of 2014 meetings)
* Have a optic calibration run plan (discussed in 01/16/2014 meeting)
* It would be nice to have real-time viewer for optics studies in commissioning (disussed in 01/16/2014 meeting)
