Project summaryThe main goal of the project is the development of front-end electronics for the readout of information for relatively recently developed multi-pixel avalanche photodiodes, which operate in the Geiger mode, as well as design solutions for developing the detector systems for the future experiments.
In the muon systems of modern large physics setups the gas filled or scintillation detectors are mainly used. Both types of detectors have their merits and disadvantages. To register the signals from the scintillation detectors vacuum photomultiplier tubes (PMT) are commonly used. However, some properties of the PMTs (large sizes, difficulty of operation in strong magnetic field, high operating voltages) limit the possibilities of their application. There is a great interest in the possibility of usage of the muon systems with the laminated structures for the modern setups, when the particle detectors alternate with the iron layers of magnet yoke (detectors are inserted inside the magnet yoke). This arrangement of detectors sets additional constraints on compactness and possibility to work in the magnetic field and the long term stability of equipment. The avalanche photodiodes (APD) of the new type, solid-state electron multipliers based on the Geiger micro-cells, satisfy these conditions. These detectors were recently proposed by Russian scientists, and so far they do not have the established name. Further in the text the Geiger Avalanche Photodiodes (GAPD) will be used. These detectors can find wide application in many fields, including high-energy physics. At the same time, in spite of the essential progress in the development of GAPDs during the last decade, there are no widely available fast amplifiers intended to work with these detectors.
Within the project framework the eight-channel application-specific integrated circuit (ASIC) amplifier chip will be developed and optimized for this type of photodetectors. This ASIC chip can be used in many applications of GAPD. The detection channel with the analog and digital outputs based on this chip will be designed and printed circuit board (PCB) will be developed and produced. In this project, the characteristics of GAPDs and the possibility of their use with the long scintillation counters intended for use in the muon systems of modern physics setups will be investigated. The design solutions will be studied and the technologies of creation, assembly and testing such type of detectors will be developed.
The results of project will become major step in the development of electronics for GAPD and new detectors on their basis for the future experiments. The specialized detection channel can be used for other applications as well.
The participants of this project have wide experience in the development of front-end electronics and large systems of detectors for the big experiments in physics of elementary particles: DELPHI (LEP, CERN), D0 (Tevatron, Fermilab), ATLAS (LHC, CERN).
