Owing to a few unique advantages, the double-dot single electron transistor has been proposed as an alternative detector for charge states. In this work, we present a further study for its signal-to-noise property, based on a full analysis of the setup configuration symmetry. It is found that the effectiveness of the double-dot detector can approach that of an ideal detector, if the symmetric c...

Measurements using the LR 115 solid-state nuclear track detector (SSNTD) depend critically on the removed thickness of the active layer during etching, which cannot be controlled by the etching period alone. For example, the bulk etch rate depends significantly on the strength of stirring during etching. We propose here a fast, inexpensive and nondestructive method based on a color commercial d...

The authors propose a microwave photon number detector with single-photon resolution using cadmium arsenide at low temperature, the graphene-like surface state acting as absorber and superconducting bulk bolometer.

The silicon microstrip detector type with nþ readout fabricated on p bulk, nþ-on-p, is a candidate to be operational in radiation environments much severer than in LHC. We characterized nþ-on-p detectors which were irradiated up to 1:1 10 protons=cm 10 years ago. The noise level and charge collection were evaluated using the ATLAS SCT readout electronics system. Radiation-induced increase in th...
