25 Tesla Resistive NMR Magnet

The world’s first Bitter NMR magnet and also the highest field magnet with uncompensated field homogeneity better than 50 ppm. It has the standard NMR bore size of 52 mm. The field homogeneity is 12 ppm over 1 cm³ by ferro-magnetic shim and the temporal instability is 3 ppm using a magnetic flux stabilizer. 40 ppb linewidths have been demonstrated with HENPEC and IZQC.
