ATLAS
The ATLAS detector was built to study proton-proton collisions at a center of mass energy of 14 TeV. It provides an excellent chance of discovering new forms of matter such as supersymmetric states. The lightest supersymmetric state is a prime candidate for the dark matter in the universe.

MicroBooNE and MINERvA
MicroBooNE studies neutrino oscillations over a short-baseline (500 m) and address recent experimental anomalies in this area that could be understood as evidence for ‘sterile’ neutrino particles, if confirmed. The MINERvA experiment is making precision measurements of neutrino-nucleus interactions in support of future neutrino oscillation experiments.

doublechooz
Double Chooz
The Double Chooz experiment, which will be performed at a commercial nuclear power station near the border between France and Belgium, will search for the last unmeasured angle of the neutrino mixing matrix with an order-of-magnitude better precision than previous experiments. A nonzero value for this mixing angle would open the possibility of searching for CP violation in neutrino oscillations.

cpv
E14 at JPARC
This group primarily focuses on the measurement of the branching ratio of a very special rare kaon decay, a k-long particle decays into a neutral pion and two neutrinos (so called the "golden" mode). This decay mode provides the cleanest and best answer to the question of CP violation in elementary particle physics that the theoretical calculation (prediction) within the so called Standard Model is unambiguous and precise. Therefore no matter what the measurement result is, standard or non-standard; it will be most fascinating.

picosecond
Large-Area Picosecond Photo-Detectors
We have proposed using micro-channel plates (MCP-PMTs) with a novel equal-time anode and with capacitive-return-path coupling to measure the time-of-flight of relativistic particles with 1 psec resolution. The proposed readout electronics for each MCP-PMT unit consists of 4 identical front-end ASICs and one DAQ ASIC that digitizes the front-end outputs, distributes the system clock, and handles all digital traffic. The front-end ASIC chip is a `time stretcher', converting the difference in times between start and stop pulses into a digital pulse with width proportional to the input time interval but stretched by a factor of 200. We are designing in the IBM 0.13um SiGe BiCMOS 8HP process, The circuitry includes a limiting amplifier and a constant-fraction discriminator. The DAQ chip then digitizes the stretched time interval. The preliminary design and detailed simulations of the front-end ASIC chip will be presented.

snoplus
SNO+
SNO+ is a new kilo-tonne scale liquid scintillator detector that will study a variety of topics in neutrino physics. The primary goal of the experiment is the search for neutrinoless double beta decay of 130Te. The experiment is located approximately 2 km underground in VALE's Creighton mine near Sudbury, Ontario, Canada.
