STANDARD FEATURES

High Sensitivity-DC SQUIDS: Magnetic Dipole Moment Noise of less than

10-12Am2 ( 10-9 EMU) RMS per root Hz for 7.6 cm access.

Low Helium Consumption - Approximately 900 days operation with 90 liters of helium.

No Helium Diffusion - All metal construction eliminates cycling system to room temperature to repump vacuum.

Heat Switch on Superconducting Shield - Can change field with system filled with helium in less than 10 minutes. About 0.2 liter of liquid per change.

Sample Access - Vertical or Horizontal Orientation.

Standard Access diameter of 7.6 cm.

Pass Through Access for Long Cores.

Performance is Independent of Liquid Helium Level .
