We present a novel Laplacian design method for a finite length magnet with perfect field homogeneity. It will be used to study TRansmit Array Spatial Encoding (TRASE) MRI at low field. As TRASE does not require the application of switched B0 gradients, we propose to build the magnet on an aluminum housing which acts both as a heat sink and effective low-frequency RF shield.
