The numbers of signal and background events for 6 different M$_{e}$ 8 values are presented in Table 4 (the mass window used is the same as the one used in previous subsection). As seen from the Table very clean signal can be obtained up to M$_{e}$ 8 ⋍ 1500 GeV. 

Reachable Λ scales for 5 different mass values are given Table 5. Comparison with Table 3 show that twofold increasing of the electron energy results in: 1 . 5 times higher values of Λ for M$_{e}$ 8 = 500 GeV, 2 times - for M$_{e}$ 8 = 750 GeV and 4 times - for M$_{e}$ 8 = 1000 GeV. 

Moreover, multi-ten TeV scales can be achieved for M$_{e}$ 8 = 1250 and 1500 GeV, which are not available at LHeC/QCDE-1.
