  This paper de­scribes the de­sign of a test beam­line for a new gen­er­a­tion of high-en­ergy, high-flux, and high-co­her­ence SR beam­lines. The beam­line will be built at ID42 of HEPS. The beam­line in­cludes two sources, a wig­gler and an un­du­la­tor, to pro­vide high-en­ergy, high ther­mal power, large size, and high-co­her­ence, high-bright­ness X-ray beams, re­spec­tively. In the cur­rent de­sign, the beam­line mainly has op­ti­cal com­po­nents such as mono­chro­ma­tors, CRLs, and fil­ters. With dif­fer­ent com­bi­na­tions of sources and op­ti­cal com­po­nents, the beam­line can pro­vide var­i­ous modes, in­clud­ing white, mono­chro­matic, and fo­cused beam. Using a Si111 DCM, the beam­line cov­ers a wide pho­ton en­ergy range from 5 to 45 keV. In the fu­ture, the beam­line will be ca­pa­ble of pro­vid­ing mono­chro­matic beam with pho­ton en­ergy over 300 keV. The wig­gler’s white beam can pro­vide high ther­mal load test con­di­tions over 1 kW. The beam­line of­fers high flex­i­bil­ity and ver­sa­til­ity in terms of avail­able beam size (from mi­crom­e­ters to over 100 mm), en­ergy res­o­lu­tion, and pho­ton flux range. Var­i­ous ex­per­i­men­tal tech­niques in­clud­ing dif­frac­tion, spec­troscopy, imag­ing, and at-wave­length mea­sure­ment can be per­formed on this beam­line.
