The possibility of polarized-proton-beam acceleration in the proposed low-field 3-TeV VLHC booster is considered. We find that the low-field combined function magnets in the booster`s long FODO cells cause an inadvertent cancellation of most depolarizing fields due to a mechanism suggested earlier by Chao and Derbenev [Part.thinspthinspAccel.thinspthinsp{bold 36}, 25 (1991)]. The strongest spin-depolarizing resonances in the 3-TeV booster seem to be similar in strength to those in the 250-GeV RHIC. Moreover, the strength of the 3-TeV booster`s strongest intrinsic depolarizing resonances decreases with energy, in contrast with the energy growth of the depolarizing resonance`s strength in most proton synchrotrons. {copyright} {ital 1999} {ital The American Physical Society }
