The MuCHAMBER® is a versitle magentic shield that can easily be modified to meet each users needs. The cubic shape has generous internal working volume of 1m x 1m x 1m with removable panels on all six sides. Maximum opening size with panles removed is 670mm x 670mm. Door opening is 472mm x 472mm. Combining both high permeability, MUMETAL® layer, and highly conductive, Aluminum layers, it achieves high attenuation (dB) across a large bandwidth (.01Hz-100kHz).  Low residual fields and high field homogenity are achievable with the degausisng coil system installed. The removable shield panels can be customized to add cable passthroughs or penetrations at the time of order to fit your exact needs. Hinged doors can be added for easy access. The MuCHAMBER® is mounted to 360 swivel casters with leveling for moving the shield around the lab. 

Measured Residual magnetostatic field: <200nT 

Measured Shielding Attenuation:
Quasi-static fields: .01-1Hz: 30dB minimum
AC Magnetic field: 10 Hz: 40dB minimum
AC magnetic field: 100 Hz: 50dB minimum
AC magnetic field: 1kHz: 60dB minimum
Attenuation(dB) = 20 log (External Field/Internal Field)
Measurements taken at center of shielded volume using low-noise fluxgate magnetometer with 100uT range. External AC excitation coil is 8ft.x 8ft and field amplitude is 16uT peak-peak.
