Product Description

Product Description

The 3-axis coil assembly consists of six coils arranged to apply magnetic bias fields and gradients across atomic samples in one of ColdQuanta’s vacuum cells, such as the RuBECi, Double MOT or miniMOT systems. The coils enable easy, low power generation of e.g. MOT fields, bias fields for atom chip traps, and make it simple to apply or cancel low-order fields. The assembly is mounted to around the vacuum cell by the use of the coil-rail system, installed standard on most of ColdQuanta’s vacuum systems. The coil assembly is designed to be driven in a standard configuration (X1, X2, Y, Z) with ColdQuanta’s four-channel coil driver. Coil sold with 3’ cable.
