- Decided what magnet to use: 2 m long 30D72 magnet with the maximum field of 2 T.
- The vaccum chamber design has to be optimized. Current chamber length 1.5 m.
- Consider symmetric detectors covering the energy range from 3 GeV to 6 GeV.
Detector width (position from the beamline) as a function of the magnetic field:
For the magnetic field of 1.5 T the detector width should be about 30 cm.
Contribution to the position/energy resolution from multiple scattering.
The converter is placed 1 m in front of the magnet. B = 1 T.
(the energy resolution of the scintillator counters corresponding to the default design is 12 MeV for 24 counters and 17 MeV for 8 counters).
