New two-dimensional position sensitive silicon detector with good position linearity and resolution

First application of the Trojan horse method with a radioactive ion beam: Study of the18F(p,α)15Oreaction at astrophysical energies

“…In particular a pair of double-sided multistrip silicon detectors (DSSSD), was used to detect the heaviest ejecta. The lighter ones were detected by using the ASTRHO (A Silicon Array for TRojan HOrse) modular system of INFN Laboratori Nazionali del Sud equipped with 8 bidimensional position sensitive detectors (BPSD, 45×45 mm 2 , 500 µm thick, spatial resolution 1 mm) similar to those described in [33,34]. For each detector the x and y position and the energy of the impinging particles were recorded together with the time of flight.…”

Performance evaluation of position-sensitive silicon detectors with four-corner readout

“…This kind of PSD structure consists of a reverse biased p + -n junction with extended lateral contacts to the nlayer in a square layout. Compared to the duo-lateral type, the multiple electrodes required on the front surface produce serious distortion in the position pattern ⎯ the commonly seen 'barrel' effect [6] ⎯ due to interaction between the electrical contacts which occurs near the corners of the active area. But the tetra-lateral type features an easy-to-apply reverse bias voltage and a small dark current.…”

“…The tetra-lateral PSD type uses only the junction side of the detector for obtaining twodimensional position having all four signal contacts on the front surface [6]. This kind of PSD structure consists of a reverse biased p + -n junction with extended lateral contacts to the nlayer in a square layout.…”

“…This ratio value of 2 is much smaller than the value of 10÷15 found in Doke et al's work. The ratio of 2 was a result of taking the value of 20 kΩ/ from previous works [6], [13] as the best starting point for the anode surface resistance, then implanting the periphery resistive strip with the highest ion dose we would consider economically viable. From a manufacturer position, one always looks to minimise the ion implantation dose.…”

“…Characteristics of isotope telescopes The telescopes consist of all Si detectors utilizing the well-established AE x E method for the isotope identification. They consist of mult-layers of Si detectors, of which top two layers are position-sensitive Si detectors (PSDs) in order to achieve a high mass resolution for isotopic analysis of incident particles and to increase the geometric factor of the telescope (Doke et al, 1987;Hasebe et al, 1988Hasebe et al, , 1992Yanagimachi et al, 1988). Each PSD provides a two-dimensional position information using the chargedivision method.…”
