It seems that QCD Explorer stage(s) of the LHeC, together with providing necessary information on PDF’s and QCD basics, could play essential role on the BSM physics, also. 

Concerning color octet electrons. LHeC/QCDE-1 will cover M$_{e}$ 8 mass up to O( 1200 GeV), whereas LHeC/QCDE-2 will enlarge covered mass range up to O( 1700 GeV). 

The discovery of e 8 at this machine, simultaneously will determine compositeness scale. 

For example, if M$_{e}$ 8 = 500 GeV LHeC/QCDE-2 with L$_{int}$ = 10 fb − 1 will be sensitive to ∧ up to 570 TeV.
