satisfy condition 0 < m_p < 4 and 0 < m_n < 4 gated w(1)=50 & w(2)=-50 20keV/channel nominal per DSSSD p+n junction strip versus n+n Ohmic strip - attachment 3 note - x/y channel ordering to be checked per DSSSD E_p versus E_n - attachments 4 & 6 check whether vertical structures (correct E_n but low E_p) are associated with specific strips or edge of DSSSD? per DSSSD E_p versus E_n -
