[1] CDC R&D Status

[1-1] Lorentz Angle Measurement (Hoshina)
   	
   K.Hoshina described a new measurement system using two
   laser beams to measure two drift length points at one
   time. This is to overcome a known vibration problem with
   the previous measurement system. The data will be read
   out with FADC's.


[1-2] Two-Track Separation (Kuroiwa)

   H.Kuroiwa showed preliminary results on the per-wire
   efficiency as a function of the two-hit distance.
   The efficiency started dropping at around 5mm in the
   two-hit distance, possibly due to space charge effects.
   More studies are necessary to draw any solid conclusions.
