The D-Pace OWS-30 Oscillating Wire Scanner Probe performs two orthogonal intensity scans of a beam in one scanning operation. An interchangeable 0.5 mm diameter tungsten wire with two legs is pivoted about an axis within the case of the instrument. A high-sensitivity ammeter is used to measure the intercepted beam current. D-Pace can provide a custom vacuum box.1

The Wire Scanner Probe can be purchased separately, or D-Pace can provide a turnkey system, complete with the probe, current meter, PC, software, cables, and optional instrument rack. The software displays 2D intensity distributions in real time as scans are performed, allowing the operator to tune and center beams. A single oscillation results in two passes of both legs of the scanning wire through the beam.

The OWS-30 Oscillating Wire Scanner Probe is under a TRIUMF technology license.
