SVT Meeting Minutes: Wednesday, August 5, 2009

Present: Amrit Yegneswaran, Anna Shabalina, Brain Eng, Dave Kashy, J.J. 
Robertson, Latifa Elouadrhiri, Peter Bonneau, Saptarshi Mandal, Werth 
Teachey

•	Discussion on the current status of the mechanical design effort. The 
alignment and manufacturing tolerances of the SVT components need to be 
established. A CLAS-note by Amrit on SVT alignment issues based on what 
other labs have done is available. Mechanical group will review the 
paper and comment on what they think is possible in regards to 
alignment, etc. for Jlab’s SVT support structure. This would include an 
independent costs analysis by the mechanical group.

•	Discussion on mechanical creep and temperature excursions and the 
effect on the SVT components (wirebonds, etc.). Research into this 
subject will be conducted.

•	The preparations for the upcoming review were discussed.  The items 
that will be presented on the SVT mechanical design need to be 
determined soon. The specifications need to be well defined for this review.

•	Anna showed her progress on the simulation of the FST. The simulation 
of the copper assemblies was discussed. Anna figured out how to add the 
geometry of the copper slot assembly into the simulation. Work is 
continuing on the FST simulation.

•	SVT silicon sensor Sources Sought Notice and the Statement of Work 
(specifications) have been completed and sent to Mitch Laney for final 
review and comments.

•	The MSU MOU has been edited and returned to Latifa. The price of the 
construction of the first modules by MSU is need next for the 
sole-source module construction procurement.

•	All of the parts of the resource loaded schedule need to be completed 
and added to the master list before funds can be dispensed to any SVT 
sub-system. It is therefore imperative to have the Mechanical Group, 
MSU, & UNH complete their detailed section of this resource loaded 
schedule.
