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.
