Radiation-resistant WDM Optical Link for Thermonuclear Fusion Reactor Instrumentation

The future International Thermonuclear Experimental Reactor (ITER) is a complex installation that will require permanent monitoring and frequent maintenance operations. The high-gamma dose rates, the high neutron fluence and other radiological hazards call for the use of remotehandled equipment. The management of heavy umbilicals connecting the control systems with the remote tools is therefore...

Optical Radiation Measurements Based on Detector Standards

A near-IR radiometer standard with similar performance to silicon trap-detectors has been developed to calibrate detectors and radiometers for absolute spectral power, irradiance, and radiance responsivities between 950 nm and 1650 nm. The new radiometer standard is utilized at the Spectral Irradiance and Radiance Responsivity Calibrations using Uniform Sources (SIRCUS) which is the reference c...

Pilot: Optical Configuration and Instrumentation

PILOT, the Pathfinder for an International Large Optical Telescope, is proposed as a 2.4 m diameter optical/infrared telescope to be located at Dome C, Antarctica. The “strawman” optical configuration and instrument suite for PILOT described here is designed to take advantage of the unique atmospheric characteristics found at this site.

Methods and Instrumentation for Bunch Shape Measurements

Bunch shape is one of the most important and interesting characteristics of a beam in ion linear accelerators. Recently detectors of bunch shape with a transverse scanning of low energy secondary electrons found application in several accelerators. The principle of operation of the detectors is based on a coherent transformation of a longitudinal structure of a beam under study into a transvers...
