If the different odd and even bin size is corrected the DNL is about 0.3 time bins (120 ps). 7.5 Radiation tolerance (OTIS1.3) The OTIS TDC chip (OTIS1.2) was part of a total ionising dose irradiation campaign in February 2005 at the X-ray irradiation facility of the CERNs microelectronics group [MIC]. Two chips were subject to irradiation and accumulated a total dose of 1 Mrad(SiO2) (chip A) and 10 Mrad(SiO2) (chip B). For the operating conditions of the X-ray tube (an accelerating voltage of Utube =40 kV and a X-ray tube current of Itube=60 mA) the dose rate (DR) at a distance of 1 cm from the collimator is given by: DR[rad(SiO2)/min] = 92 + 631 : 30 × Itube [mA] A total ionising dose of 1 Mrad is accumulated within less than half an hour. No significant changes in the power consumption or in the DLLs control voltage were found after the irradiation campaign. The measured voltage and currents for the two chips before and after irradiation are given in table 7. The third column gives the results from a repeated measurement after 3 1 2 months of chip storage at room temperature. The small change of the values compared to the ones measured during the irradiation campaign is caused by a different ambient temperature. Figure 21 23
