====== AT-TPC ======

Currently the design of the AT-TPC is in the conceptual stages.  Presently the two primary objectives are to: 
  - produce a representation of the detector that can be used to convey the basic features to the public for talks & proposals
  - evaluate the mechanics of connecting the electronics to the pad plane
 \\   
__Overview of AT-TPC Chamber__ This design assumes FEC dimensions of 1.75cmx14.0cmx19.0cm which allows 3 connectors to the pad plane instead of 4.  This implies 3 ASICs per board and would require 46 cards for the number of channels.  A maximum of 48 cards will fit in the existing space.\\

__Endview of AT-TPC in Solenoid with Radial Electronics__ This design assumes FEC dimensions of 2.0cmx14.0cmx25.0cm which is thought to be the T2K dimensions.  Assuming a design that includes 4 ASIC's per card a total of 35 FEC's are required.  Two radial arrays of 18 FEC's each do not fit in the available space of the pad plane.\\

__Endview of AT-TPC with FEC Options__ This design assumes FEC dimensions of 1.0cmx9.3cmx17.0cm which are now known to be too small.\\
