The characteristic of the dc current gain degradation with dose and current injection level for SiGe HBT during 60Co gamma irradiation are measured and analyzed. Additionally, the typical dc and ac parameters degradation mechanisms are discussed. The experimental results of the dc and ac electronic parameters before and after irradiation are shown to result in the base current Ib, the...

The first upgrade of the ATLAS Pixel Detector is the Insertable B-Layer (IBL), just installed in May 2014 in the core of ATLAS. Two different silicon sensor technologies, planar n-in-n and 3D, were used, connected with the new generation 130nm IBM CMOS FE-I4 readout chip via solder bump-bonds.
Production quality control tests were set up to verify and rate the performance of the modules...

A bidimensional dosimeter consisting of 12x12 pixels on a 2.5x2.5cm2-wide polycrystalline Chemical Vapour Deposited diamond (pCVD) has been manufactured. The prototype has been tested under Intensity Modulated Radiation Therapy (IMRT) fields for a possible application in pre-treatment verifications of cancer treatments.
Tests have been performed under a 6 MVRX beam with an IMRT field for...

The experimental system we established for evaluating the single event effects (SEE) and total ionizing dose effects (TID) of Xilinx MicroZed Zynq-7010 SoC was introduced in the paper. The variation of the output current of the test SoC during 60Co gamma irradiation was measured. The irradiation dose rate was 0.04Gy(Si).s-1. The test SoC output current changing characteristics under the...

The architecture of SRAM and single event upset cross section computation approach are presented. Deposited energy and single event upset cross section are analyzed by the simulation of single event upset in different characteristic dimensions SRAMs induced by low energy proton using Monte-Carlo code Geant4. The simulating result shows that the deposited energy will decrease with the increase...
