Fermilab has recently completed a series of 2 m long model magnets to develop and prove the design of the MQXB Inner Triplet Quadrupoles for the LHC. The MQXB has a 70 mm bore, and provides a gradient of 215T/m at IP2/8 and 205T/m at IP1/5. In the high luminosity interaction regions, the magnets are subjected to large energy deposition from particles generated by the collisions at the IP. The presentation will include the quench performance, thermal margin, and field quality demonstrated in the model magnets. Furthermore, the series of model magnets was constructed with a number of design and production process variants, and the effect of these variations on magnet performance will be discussed.
