Hybrid Pixel Detectors

ASI's imaging technology is based on the hybrid pixel imaging technology developed within the international Medipix collaboration.

The detection principle is based on the direct conversion of radiation into charge in a sensitive layer. It can be electronically collected, detected and processed by an imaging ASIC. For example, absorption of X-rays in a silicon sensor leads to the generation of electrons and hole pairs in the sensor with a charge proportional to the X-ray energy. The applied electric field allows fast signal collection with small spread of the signal. Therefore, high sensitivity and high spatial resolution can be achieved.

The readout principle is based on pixelized imaging ASICs. Each sensor pixel is bump bonded to an ASIC pixel by a miniature bump bond. The basic architecture of each ASIC pixel consists of a signal amplifier, a discriminator and a counter. The threshold level can be controlled by the user through software and only incoming pulses above the threshold are counted. The digital detection provides noise free detection of X-rays and because of the energy threshold also spectral resolution.

Hybrid Pixel Detectors are a kind of ionizing radiation finder comprising of a variety of diodes. They are made to work in single-photon mode are known as Hybrid Photon Counting Detectors (HPCDs). These finders are intended to check the quantity of hits inside a specific time span. They have gotten a norm in most synchrotron light sources and X-beam location applications.

Hybrid Pixel Detectors are developed by holding a pixelated sensor (generally a variety of semiconductor diodes) to an application specific integrated circuit (ASIC). The ASIC gives fundamental charge-taking care of and readout hardware to each pixel of the sensor. The intensity of mixture pixels is that the ASIC rationale can be custom fitted to make identifiers streamlined for a specific application. The innovation is especially fit to synchrotron light sources, where the quantity of test procedures is colossal and the interest for specific locators is high.

Inside it the indicator part comprises basically of a micro strip identifier structure, each strip being partitioned into some number of short pieces, which establish the pixels. The sensor exhibit and the coordinating read-out chip are handled freely and are associated together just in the last advance. Thusly the material and procedures can be exclusively upgraded for the genuine reason for example identifier and gadgets. This methodology makes it conceivable to accomplish quick enough read-out and radiation hardness good with the LHC condition. The finder substrate is high resistivity silicon, albeit different materials than silicon, for example precious stone like diamond, are likewise thought of.

The advancement of hybrid pixel indicators for molecule identification with high spatial goal in high vitality material science tests has spun off various improvements with applications in imaging, most eminently biomedical imaging, and furthermore imaging in X-beam space science.

For the part of sensing element every pixel covers, actually, a little zone (10^(−4)cm2) over a slim (300μm) layer of silicon. It subsequently displays a low capacitance (0.2 - 0.4pF), which is commanded by the coupling to the neighbouring pixels instead of to the rear plane. The low capacitance is one of the key focal points of pixel identifiers since it permits quick sign moulding with extremely low clamour.

What is Hybrid Pixel Detectors?

Hybrid Pixel Detectors are ionizing radiation finder comprising of a variety of diodes dependent on semiconductor innovation and their related gadgets. The expression "mixture" originates from the way that the two principle components from which these gadgets are fabricated, the semiconductor sensor and the readout chip (otherwise called application-explicit incorporated circuit or ASIC), are produced autonomously and later electrically coupled by methods for a knock holding process. Ionizing particles are distinguished as they produce electron-opening sets through their connection with the sensor component, generally made of doped silicon or cadmium telluride. The readout ASIC is fragmented into pixels containing the fundamental gadgets to enhance and measure the electrical signs incited by the approaching particles in the sensor layer.
