Description
In some external microbeam applications the knowledge of a precise number and timestamp of delivered ions is required. Among others, these include single event upsets, timing applications and investigation of radiation effects on living cells. Different triggering techniques have been developed to fulfill this requirement. In our approach, exit window acts as a trigger detector at the same time. Approximately 6μm thick membrane made of low cost optical quality scCVD diamond material was produced at CEA-Saclay. The membrane was mounted to a flange as a vacuum exit window and fully characterized at Zagreb microprobe facility. The negligible intrinsic noise of the device provides an excellent signal-to-noise ratio, even for energetic protons. In addition, the outstanding results of the radiation-hardness test indicate a wider possible range of device applications, including those that involve high currents of charged particles or long exposure to radiation. Production, characterization and applications in time resolved charge transport measurements of the newly developed membrane detector will be presented.
