    Description
In my talk I will present the results of the first fabrication of
n-on-n 3D detectors. The sensors have been irradiated with neutrons at
fluences up to 1E17n/cm 1 M-ev/equivalent. Using the TCT set up
available at CNM we have been able to do the  measurements before
irradiation both of the charge collection efficiency and the timing
performance using a 50x50 pixel array with a pitch of 50um.  Using a
CFD of 50%  we can get a timing resolution of 83ps before irradiation
at room temperature. Reuslts on the irradiated detectors will also be
presented.
