Abstract

We present the design and preliminary calibration results of a novel highly miniaturised particle radiation monitor (HMRM) for spacecraft use. The HMRM device comprises a telescopic configuration of active pixel sensors enclosed in a titanium shield, with an estimated total mass of 52 g and volume of 15 cm$^3$. The monitor is intended to provide real-time dosimetry and identification of energetic charged particles in fluxes of up to 10$^8$ cm$^{-2}$ s$^{-1}$ (omnidirectional). Achieving this capability with such a small instrument could open new prospects for radiation detection in space., Comment: 17 pages, 15 figures

Abstract

We present a conceptual design for a low-mass, all pixel vertex detector using the CMOS quadruple well INMAPS process, capable of working in the very high luminosities exceeding 10^36 /cm^2 /sec that can be expected at the next generation e+e- B factories. We concentrate on the vertexing requirements necessary for time-dependent measurements that are also relevant to searches for new physics beyond the Standard Model. We investigate different configurations and compare with the baseline designs for the SuperB and BaBar experiments., Comment: 8 pages and 8 figures, submitted to NIM

Abstract

Progress is reported on the development and testing of Monolithic Active Pixel Sensors (MAPS) for a Si-W ECAL for the ILC. Using laser and source setups, a first version of the sensor has been characterised through measurements of the absolute gain calibration, noise and pedestal. The pixel-to-pixel gain spread is 10%. Charge diffusion has been measured and found to be compatible with simulation results. The charge collected by a single pixel varies from 50% to 20% depending on where it is generated. After adding detector effects to the Geant4 simulation of an ILC-like ECAL, using the measured parameters, the energy resolution is found to be 35% higher than the ideal resolution, but is still lower than the resolution obtained for an equivalent analogue ECAL., Comment: 4 pages, 5 figures, to appear in the proceedings of the LCWS08 conference

Abstract

In this paper we present a novel, quadruple well process developed in a modern 0.18mu CMOS technology called INMAPS. On top of the standard process, we have added a deep P implant that can be used to form a deep P-well and provide screening of N-wells from the P-doped epitaxial layer. This prevents the collection of radiation-induced charge by unrelated N-wells, typically ones where PMOS transistors are integrated. The design of a sensor specifically tailored to a particle physics experiment is presented, where each 50mu pixel has over 150 PMOS and NMOS transistors. The sensor has been fabricated in the INMAPS process and first experimental evidence of the effectiveness of this process on charge collection is presented, showing a significant improvement in efficiency., Comment: 15 pages, 10 figures, submitted to "Sensors"

Abstract

A novel design for a silicon-tungsten electromagnetic calorimeter is described, based on Monolithic Active Pixel Sensors (MAPS). A test sensor with a pixel size of 50x50 um2 has been fabricated in July 2007. The simulation of the physical sensor is done using a detailed three-dimensional charge spread algorithm. Physics studies of the sensor are done including a digitisation algorithm taking into account the charge sharing, charge collection efficiency, noise, and dead areas. The influence of the charge sharing effect is found to be important and hence needs to be measured precisely., Comment: 4 pages, 4 figures. Talk presented at LCWS07

Abstract

This paper reviews the development of CMOS Monolithic Active Pixel Sensors (MAPS) for future vertex detectors. MAPS are developed in a standard CMOS technology. In the imaging field, where the technology found its first applications, they are also known as CMOS Image Sensors. The use of MAPS as a detector for particle physics was first proposed at the end of 1999. Since then, their good performance in terms of spatial resolution, efficiency, radiation hardness have been demonstrated and work is now well under way to deliver the first MAPS-based vertex detectors., Comment: Invited talk at International Symposium on the Development of Detectors for Particle, AstroParticle and Synchrtron Radiation Experiments, Stanford Ca (SNIC06) 4 pages, pdf, 2 TIFF figures, PSN0006

Abstract

The physics goals at the future e+e- linear collider require high performance vertexing and impact parameter resolution. Two possible technologies for the vertex detector of an experimental apparatus are outlined in the paper: an evolution of the Hybrid Pixel Sensors already used in high energy physics experiments and a new detector concept based on the monolithic CMOS sensors., Comment: 8 pages, to appear on the Proceedings of the International Workshop on Linear Colliders LCWS99, Sitges (Spain), April 28 - May 5, 1999

Abstract

The physical performance characteristics of a prototype scanning digital mammography (DM) system have been investigated. The I-ImaS system utilises CMOS MAPS technology promoting on-chip data processing; consequently statistical analysis is therefore achievable in real-time for the purpose of exposure modulation via a feedback mechanism during the image acquisition procedure. The imager employs a dual array of twenty CMOS APS sensing devices each individually coupled to a 100 [micro]m thick thallium doped structured CsI scintillator. The x-ray performance of the sensors was characterised where the presampled modulation transfer function (MTF), normalised noise power spectrum (NNPS), and the detective quantum efficiency (DQE) was determined. The presampled MTF was measured utilising the slit technique and was found to be 0.1 at 6 1p/mm. The NNPS measured utilising a W/A1 target/filter combination hardened with 38 mm PMMA was seen to decrease with increasing exposure as expected and the manifesting DQE was 0.30 at close to zero spatial frequency at an exposure of 1.75 mR. Preliminary image stitching of the individual steps acquired from the scanning system is presented. A conventionally acquired image that is without the implementation of beam modulation or off-line intelligence is compared and contrasted to an intelligently off-line processed image. Results indicate the implementation of real-time intelligence into the image acquisition phase of digital mammography is foreseeable. Index Terms--CMOS active pixels sensors, data acquisition, detector characterisation, digital mammography, medical imaging.

Abstract

We are developing CMOS monolithic active pixel sensors for high energy physics applications. We have successfully produced three test structures. They feature several different pixel types including a Flexible APS (FAPS). The FAPS has a 10 deep pipeline in each pixel. This is specifically designed with the beam structure of the TESLA proposal for the Linear Collider in mind. Here results demonstrating that the standard active pixel devices are still operating well after a fluence of [10.sup.14] p/[cm.sup.2] will be reported. Furthermore, the response of the FAPS to minimum ionizing particles (MIPs) from a [sup.106]Ru [beta]-source are presented. The obtained S/N ratio for the 10 cells of the FAPS varies between 15 and 17. Index Terms--Active pixel sensors, CMOS imaging, solid-state detectors, tracking.

Abstract

CMOS monolithic active pixel sensors are currently developed for particle physics vertex detectors. Their radiation resistance has already been proved to be high enough for the devices to be used at machines like the linear coilider, where the radiation fluence is expected to be of the order of [10.sup.12] proton/[cm.sup.2]. However, in order to address more radiation-harsh environments, we proposed a novel sensor structure based on the deep n-well, which is found in triple-well CMOS technologies. Potential benefits arising from this technology are investigated and simulation results for standard and novel structures compared. Index Terms--Minimum ionizing particle, monolithic active pixel sensors.
