Pixel technologies - Monolithic detectors

ORAL

Monolithic detectors integrate sensor and readout in one piece of silicon and therefore present advantages compared with hybrid detectors in terms of detector assembly, production cost and detector capacitance. Despite years of intensive research they have not yet been widely adopted for high energy physics. Several functional devices on high resistivity silicon have been developed but often...

ORAL

High voltage particle detectors in commercial CMOS technologies are detector family that allows implementation of low-cost, thin and radiation-tolerant detectors with good time resolution. The unique property of these detectors is that the pixel electronic is embedded inside sensor diodes. For this reason, we refer to the detector type as the "smart diode” array - SDA. In the R/D phase of the...

Pixel technologies - Monolithic detectors

ORAL

Monolithic Active Matrix with Binary Counters (MAMBO) V ASIC has been designed for detecting and measuring low energy X-rays from 6-12keV. A nested well structure with a buried n-well (BNW) and a deeper buried p-well (BPW) is used to electrically isolate the detector from the electronics. BNW acts as an AC ground to electrical signals and behaves as a shield. BPW creates a homogenous electric...

ORAL

The Arachnid collaboration has been set up in the UK to develop CMOS Monolithic Active Pixel Sensors. The first device of this collaboration is named Cherwell. The Cherwell device consists of several arrays of pixel optimised either for vertexing or for calorimetry. For the former, two subarrays were designed. The first one has 96x48 pixels on a 25 um pitch. Each pixel consists of a low-noise...

Pixel technologies - Monolithic detectors

ORAL

The use of different semiconductor technologies in the field of particle detector has been always limited by the effects of radiation in both the sensors and the processing circuitry. This fact has encouraged the teams working in future developments to evaluate the use of different technological approaches to minimize the impact of radiation by using new detector material, connections and...

19. Monolithic Pixel on High Resistance Substrate and Sparsifying Redaout Architecture

Pixel technologies - Monolithic detectors

ORAL

We start by presenting the latest results on the LePix sensor, an innovative Monolithic Active Pixel Sensor (MAPS) aimed at tracking/triggering tasks where high granularity, low power consumption, low material budget, radiation hardness, and production costs are a concern. The detector is built in a 90nm CMOS process on a substrate of moderate resistivity. This allows charge collection by...

Pixel technologies - Monolithic detectors

ORAL

Reliable data on the ionising radiation environment are regarded as very important to ensure an efficient design and operation of spacecraft. Engineering such sensors, and their cost, anyway, still represents a limitation to their widespread adoption. Here we present a Highly Miniaturised Radiation Monitor (HMRM), developed by the Science and Technology Facilities Council and Imperial College...

16. PImMS1 and PImMS2, monolithic CMOS event-triggered time-stamping image sensors with storage of multiple timestamps at 25ns resolution

ORAL

PImMS, or Pixel Imaging Mass Spectrometry, is a family of high-speed monolithic CMOS imaging sensors tailored to the requirements of mass spectrometry and allied fields. PImMS pixels each compare step events of collected charge to an adjustable threshold, storing up to four significant events inside the pixel as 12-bit timestamps with a time resolution of 25ns. The pixels may be individually...

Pixel technologies - Monolithic detectors

ORAL

Monolithic CMOS Pixels (MAPS) integrate on the same silicon substrate the radiation sensor element with the processing electronics. Their fabrication is possible through an easy access to commercial high-volume foundries, resulting in low costs and high yield. However in the standard implementation these devices suffer from two major limitations. First, only NMOS transistors are allowed on top...
