Question of the Referees:
A more detailed description of the chambers, especially an evaluation
of the performances required by the physics (ex. resolution, calibration
and alignment errors necessary to get M = 10 MeV in
Details on the calibration strategy and alignment, especially for the
consequences in the chamber design. An assessment on the possibility
to make prototypes. A plan on the manpower necessary to build, calibrate
and operate the chambers, including laboratory responsibilities.
