[Nikolai Smirnov]

 Dear All,

 Let me comment on the status of 1. mm gap MPGD in "forward" position.
 It is clear that such a kind of gas detector can be useful only with high
tracking efficiency: it means with a very high gas gain.
 That is why the only option is MMG (my opinion).
 My measurements with two 10x10 cm2 MMG detectors demonstrated that stable
operation with very high gain is possible.
 With Cosmic setup the tracking efficiency are:
   Ar + CO2 (20%) -- 94%.   Ar + isoButane (10%) -- 98%.
  But the conclusion can be done only if the same result can be repeated
for the reasonably large detector(s) -- like TPOT chambers.

  Alternative options:
  - small drift (micro TPC). Three-four (or more) "points" in space with
the "standard" space resolution.
  - ScFibers to solve all problems including space

  Best regards, Nikolai.
.
