The T2K experiment is a long baseline neutrino oscillation experiment. Its main goal to measure the last unknown lepton sector mixing angle θ13 by observing νe appearance in νμ beam. It also aims make precision measurement of known parameters, Δm232 and sin22θ23, via disappearance studies. Other goals include various cross-section measurements sterile searches. uses an intense proton beam generated J-PARC accelerator Tokai, Japan, composed beamline, near detector complex (ND280), far...
The T2K (Tokai-to-Kamioka) experiment is a long baseline neutrino oscillation in Japan, for which near detector complex (ND280), used to characterize the beam, will be built 280 m from target off-axis direction of beam produced using 50 GeV proton synchrotron J-PARC (Japan Proton Accelerator Research Complex). central part ND280 including 3 large Time Projection Chambers based on Micromegas gas amplification technology with anodes pixelated into about 125,000 pads and requiring therefore...
Today with the advent of intense radioactive beams, we have access to nuclear spectroscopy and reaction studies nuclei far from stability. It has been demonstrated that Time Projection Chambers (TPC) method can be very effective as an active target for such yielding low thresholds, efficiency luminosity [1]. To this end a Generic Electronic system TPCs (GET) is in development will cover small medium sized instrumentation (64 32 k channels) relatively wide charge dynamic ranges event rates up...
Two prototype chips for the analogue readout of silicon strip detectors in ATLAS Semiconductor Tracker (SCT) have been designed and manufactured, 32 channel 128 versions, using radiation hard BiCMOS DMILL process. The SCTA chip comprises three basic blocks: front-end amplifier, pipeline output multiplexer. circuit is a fast transresistance amplifier followed by an integrator, providing shaping with peaking time 25 ns, buffer. front end values are sampled at 40 MHz rate stored 112-cell deep...
A low-background Micromegas detector has been operating in the CAST experiment at CERN for search solar axions during first phase of (2002–2004). The detector, made out low radioactivity materials, operated efficiently and achieved a very high level background rejection (5 × 10−5 counts keV−1 cm−2 s−1) without shielding.

The recent progresses in detector developments have raised the requirements for associated readout electronics. High-end oscilloscopes are well adapted test and characterization setups, but their cost per channel is high number of channels very limited. Precision benches can also make use ADC-based fast digitizers, most these modules expensive performing house few channels. progress speed Switch Capacitor Arrays (SCA) now permits offering sampling rates far above 1 GHz over 12 bits at low...
The High Energy Stereoscopic System (H.E.S.S.) is one of the three arrays imaging atmospheric Cherenkov telescopes (IACTs) currently in operation. It composed four 12-meter and a 28-meter one, sensitive to gamma rays energy range ~30 GeV - 100 TeV. cameras 12-m recently underwent substantial upgrade, with goal improving their performance robustness. upgrade involved replacing all camera components except for photomultiplier tubes (PMTs). This meant developing new hardware trigger, readout,...
Abstract The Compact Muon Solenoid collaboration is designing a new high-granularity endcap calorimeter, HGCAL, to be installed later this decade. As part of development work, prototype system was built, with an electromagnetic section consisting 14 double-sided structures, providing 28 sampling layers. Each layer has hexagonal module, where multipad large-area silicon sensor glued between electronics circuit board and metal baseplate. pads approximately 1.1 cm 2 are wire-bonded the readout...
