Test results are reported on TQS02a, a second model in support of the development of a large-aperture Nb{sub 3}Sn superconducting quadrupole for the US LHC Accelerator Research Program (LARP). The magnet uses key and bladder technology with supporting iron yoke and an aluminum shell. Changes from the previous first model (tested in 2006) include: (1) Titanium island poles; (2) no axial island gaps during reaction; and (3) RRP Nb3Sn conductor. Design changes resulted from previous tests with three different magnet assemblies (TQS01a, TQS01b and TQS01c) using coils with bronze segmented islands, with gaps and MJR conductor The paper summarizes the assembly, cool-down and performance of TQS01a, TQS01b, TQS01c, and TQS02 and compares measurements with design expectations.
