Meeting Minutes:

1. About SMT monitoring [Xiaoling Fan]
The NWU group has been working on developing tools for monitoring and  calibrating the SMT, using the secondary data path. Most of the transparencies shown by Xiaoling can be found on his homepage 
http://svxjava.phys.nwu.edu/. There is a bit3 interface and a 68k processor (runnning VxWorks) in the VME crate. SMT data come from the sequencers (on the  platform) via Glink to the VRB's. The bit3 and the 68k have access to these data via VME (see http://svxjava.phys.nwu.edu/2nd_datapath.html). The 68k can access data in a special buffer in the VRB and send it to the 2nd data path host (presently a SGI). Software to generate and process monitoring information exists, as well as for downloading from the online database.
Quantities used for monitoring are hitmaps, mean and sigma of pulseheight,..

2. STT monitoring discussion

3. Goals for Nov19 meeting:
Tentative goals for the next STT engineering meeting (comments solicited):
   * understand influence of monitoring requirements on design 
   * make sure that tools for testing, monitoring, in situ diagnostic are              foreseen in design
   * make sure we understand all quantities (e.g. alignment info., beam 
      position,...) that need to be available to trigger, 
      provide for their   downloading and storage
   * finalize and sign off on motherboard design
   * decide on cluster algorithm
   * first pass at VHDL code for cluster finder and hit filter
   * make comparison of merits/problems with processors for track fitting
     (decide on processor if possible)
   * sign off on data transmission protocols
