The latest test beam results of 3D detectors fabricated with poly-crystalline
chemical vapor deposition (CVD) diamonds will be shown. The devices have
50$\mu$m $\times$ 50$\mu$m cells with columns 2.6$\mu$m in diameter. In
one of the devices the cells were ganged in a 3$\times$2 cell pattern and
in the other the cells were ganged in a 5$\times$1 cell pattern to match
the layouts of the pixel read-out chips currently used in the CMS and
ATLAS experiments at the LHC, respectively. In beam tests, using tracks
reconstructed with a high precision tracking telescope, both devices
achieved tracking efficiencies greater than 97\%. In the same beam tests,
the first pulse height distributions from poly-crystalline CVD
diamond 3D pixel devices were measured and will be presented. Finally,
the latest test beam results of irradiated poly-crystalline CVD
diamond pad and pixel detectors will be presented.
