Pixels (including CCD's) - Charged particle tracking
ORAL
Micro-systems, based on MEMS technology, have been used in miniaturized low power and low mass smart structres in medicine, biology and space applications. Recently similar features found their way inside high energy physics with applications in vertex detectors for High-Luminosity LHC Upgrades, with 3D sensors, 3D integration and efficient power management using silicon micro-channel...

An improved technology for double-sided 3D sensors with passing-through columns has been developed at FBK in collaboration with the University of Trento and INFN for the fabrication of 3D pixels for the ATLAS IBL [1]. The IBL production was successfully completed in 2012, with good results in terms of electrical characteristics and yield. On the same production wafers (p-type, 230±20 μm...

Pixels (including CCD's) - Charged particle tracking
The aim of AEgIS is to measure the gravitational acceleration for anti-hydrogen in the Earth’s gravitational field, thus testing the Weak Equivalence Principle, which states that all bodies fall with the same acceleration, independent of their mass and composition. AEgIS will make use of a silicon detector in order to measure the deflection of anti-hydrogen from a straight path under the...

Monolithic detectors integrate sensor and readout in one piece of silicon and therefore favorably compare with hybrid detectors in terms of detector assembly, production cost and detector capacitance. Several functional devices on high resistivity silicon have been developed but often require fabrication steps incompatible with high volume manufacturing in standard semiconductor foundries....

The high-voltage (HV) CMOS pixel sensors offer several good properties: a fast charge collection by drift, the possibility to implement relatively complex CMOS in-pixel electronics and the compatibility with the commercial processes. The sensor element is a deep-n-well diode in a p-type substrate. The n-well contains CMOS pixel electronics.
The main charge collection mechanism is drift in a...

Within the R&D activities for the upgrade of the ALICE Inner Tracking System (ITS), Monolithic Active Pixel Sensors (MAPS) are being developed and studied, due to their lower mass (~0.3% X/X0 for the inner layers) and higher granularity (~20 μm x 20 μm pixels) with respect to the present pixel detector.
This paper presents the design and characterization results of the Explorer0 chip,...

Pixels (incl. CCD's) - X-ray imaging
ORAL
We are developing monolithic pixel detectors using a Silicon-on-Insulator (SOI) technology for X-ray and charged particle applications. It is based on a 0.2 um CMOS fully-depleted (FD-)SOI process of Lapis Semiconductor Co. Ltd. The SOI wafer consists of a thick, high-resistivity substrate for the sensing part and a thin Si layer for CMOS circuits.
To overcome back-gate effect affected by...

We have been developing monolithic active pixel sensors based on the Silicon-On-Insulator (SOI) CMOS technology, called XRPIX, for next-generation X-ray astronomy satellites. Compared to CCDs, which are currently used as standard sensors for X-ray astronomy, our devices have much better time resolution of ~ microsecond since they can issue triggers to determine X-ray arriving time. Therefore,...

The successful heavy flavor factory KEKB, operating between 1999 and 2010 at KEK, Tsukuba, Japan, is currently being upgraded to SuperKEKB, whichis foreseen to start commissioning in the fall of 2014. SuperKEKB will provide an instantaneous luminosity of 8x1035 cm2/s, 40 times higher than the current world record set by KEKB. For SuperKEKB, a nano-beam scheme is applied to achieve this...
