Neutral Particle Beam Distributed Data Acquisition System

Comparison of Laser and Neutral Particle Beam Discrimination

The relative ability of lasers and neutral particle beams (NPBs) to discriminate reentry vehicle (RV) and anti-satellite (ASAT) decoys is pivotal in assessing their relative worth as strategic defenses. This report evaluates their ability and assesses their relative contributions, concluding that NPBs can typically discriminate about 100 times as many objects as can lasers, and do so with signi...

Practical Considerations for Designing a Remotely Distributed Data Acquisition System

Distributed Data Acquisition System for Pachmarhi Array of Čerenkov Telescopes

Pachmarhi Array of Čerenkov Telescopes (PACT) consists of a 5×5 array of Čerenkov telescopes deployed over an area of 100 m × 80 m, in the form of a rectangular matrix. The experiment is based on atmospheric Čerenkov technique using wavefront sampling technique. Each telescope consists of 7 parabolic mirrors mounted para-axially on an equatorial mount. At the focus of each mirror a fast phototu...

A Smart Network Sensor System for Distributed, Synchronous Data Acquisition

Typical test and monitoring systems are based on stand-alone instrumentation and require point-to-point analog wiring, which usually results in cumbersome cabling and connectors, bulky instrumentation, susceptibility to EMI/RFI noise pick up, lack of system flexibility, and a compromised signal-to-noise ratio (SNR). This paper describes a smart network sensor solution with multi-drop sensor arc...

An alpha particle measurement system using an energetic neutral helium beam in ITER (invited).

An energetic helium neutral beam is involved in the beam neutralization measurement system of alpha particles confined in a DT fusion plasma. A full size strong-focusing He(+) ion source (2 A, the beam radius of 11.3 mm, the beam energy less than 20 keV). Present strong-focusing He(+) ion source shows an emittance diagram separated for each beamlet of multiple apertures without phase space mixi...
