The surface detector array of the Telescope Array experiment

The Karoo Array Telescope

The Karoo Array Telescope (KAT) will be a “1% demonstrator” for the SKA, located in a radio quiet reserve in the Karoo region of the Northern Cape province of South Africa. Besides developing technologies for the SKA project, the KAT will perform wide-field surveys that will be precursors to the eventual SKA products. The nominal specification for the KAT are listed, and the proposed science th...

30TH INTERNATIONAL COSMIC RAY CONFERENCE Calibration and monitoring of the air fluorescence detector for the Telescope Array experiment

The air fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been constructed in a dessert of Utah, USA. We can measure the longitudinal developments of EASs directly with the FDs by detecting air fluorescence lights and determine the primary energies of ultra-high energy cosmic rays. In order for accurate observation and measurements of EASs, elaborate detector calibrations...

The FPGA Pixel Array Detector

A proposed design for a reconfigurable x-ray Pixel Array Detector (PAD) is described. It operates by integrating a high-end commercial field programmable gate array (FPGA) into a 3-layer device along with a high-resistivity diode detection layer and a custom, application-specific integrated circuit (ASIC) layer. The ASIC layer contains an energy-discriminating photon-counting front end with pho...

Callibration of a homemade 4-fold Water Cherenkov Detector array, by detection of EAS events

The Cable Array Robot: Theory and Experiment

Cable array robots are a class of robotic mechanisms which utilize multiple actuated cables to manipulate objects. This paper discusses the defining characteristics and the important issues relating to this class of robots. One particular type of cable array robot with three cables is presented in detail including kinematic relations and dynamic modeling. The resulting models are used to design...
