DPS ready for dust testing

The dust position sensor (DPS) is finished and ready to give the position of its first dust particles during a test run in the small accelerator tomorrow. Similar to the dust trajectory sensor (DTS), DPS reads the pulses from induced charges on a grid of wires as a charged particle flies through. Comparing the pulses from each wire allows us to pinpoint the position of the particle. Unlike the DTS, the DPS is small enough to fit inside the beamline and can be placed in a number of locations.
