A test beam telescope has been built using the ALIBAVA system to drive its
data acquisition. The basic telescope planes consist in four XYT stations. Each
station is built from a detector board with two 80-micron-pitch sensors,
mounted one in each side and their strips crossing at 90 degrees. The
ensemble is coupled to an ALIBAVA daughter board. These stations act as
reference frame and...

Planar n-in-p strip sensors produced by Hamamatsu Photonics were irradiated in consecutive irradiation steps with pions of 280 Mev/c, protons of 25 MeV/c and reactor neutrons resulting in a combined fluence of up to 2.8x1015 neq/cm2.
The 320 mum thick devices with p-stop interstrip isolation structures are investigated using electrons from a Sr90 source based on the ALIBAVA readout system....

Effects of long term applied bias on charge collection properties in highly irradiated and annealed FZ n+-p silicon microstrip detectors were examined using the Alibava read-out system and Edge-TCT. A significant drop of both collected charge and the leakage current is observed after keeping the detectors under bias for longer periods of time (>1000 min). The time pattern is found to be fully...

We investigate the charge collection efficiency of specially designed charge multiplication silicon strip detectors produced by MICRON in Liverpool under the framework of the CERN RD50 collaboration. Sensors are tested before and after proton and neutron irradiation to fluences of 1e15 and 5e15 neq/cm^2. Charge multiplication structures on these devices include varying diffusion times and...

Dedicated sensors provided by RD50 were irradiated with neutrons or protons to 1e15neq/cm2 and 5e15neq/cm2. Charge collection, Signal to noise and leakage current of sensors with different pitch to width ratios have been measured as a function of annealing time and will be shown.

This project aims to fabricate p-type pixel detectors with a small gain, already shown in their pre-irradiated responses. It can be hoped that the gain implemented in the non-irradiated devices could retain some effect also after irradiation, with a higher multiplication factor with respect to standard structures. In addition, a moderate multiplication value will allow the fabrication of...

Protection of AC coupling capacitors from beam splashes has been studied on the heavy irradiated HPK ATLAS07 mini-sensors with special structures, BZ4A,B,C and D, for p-stop ion concentrations 2e12, 4e12 and 1e13 ion/cm^2. Punch through voltage is rapidly increasing with neutron fluence from 4e14 neq/cm^2 to 2e15neq/cm^2 for all tested ion concentrations and for 1E13 ion/cm^2 it is...
