The Cosmological Advanced Survey Telescope for Optical and UV Research (CASTOR) is a proposed CSA mission that would make unique, powerful, lasting contribution to astrophysics by providing panoramic, high-resolution imaging in the UV/optical (0.15 - 0.55 μm) spectral region. This versatile `smallSAT'-class far surpass any ground-based optical telescope terms of angular resolution, provide ultra-deep three broad lters supplement longer-wavelength data from planned international dark energy...

AbstractAbstractThe reactivity measurement in a subcritical assembly using the area ratio method is affected by detector location and needs to be corrected for spatial dependence. One of approaches calculate correction factor based on steady-state numerical simulation as proposed Bell Glasstone. This paper discusses evaluation BRAHMMA (BeO Reflected And HDPe Moderated Multiplying Assembly) assembly, India. The factors have been used correct experimentally measured values from at different...
Associated particle technique (APT) for detection of explosives is well established but has been implemented mostly fixed portal systems. In certain situations, a portable system required where the suspect object cannot be moved from site. This paper discusses development APT in single-sided geometry which can transported to site and requires only one-sided access object. The comprised D-T neutron source bismuth germanate (BGO) detectors on module. Different aspects have discussed such as...
AbstractAbstractThe use of accelerator-driven systems for incineration nuclear waste and energy production requires monitoring different parameters that govern reactor safety. One the most important is multiplication factor keff. The present paper describes results experiments carried out on a subcritical system (BRAHMMA) using pulsed neutron source. value keff obtained from time responses core were measured in situ detectors after insertion pulse matches well with calculated value.
The online reactivity monitoring of accelerator-driven systems is a crucial issue in reactor control and monitoring. area-ratio method one the techniques for measuring subcritical using pulsed neutron source. This technique has been used to measure at different locations assembly BRAHMMA developed Bhabha Atomic Research Centre, India. Since measured by spatially dependent on detector location, Bell-Glasstone correction factor was correct reactivity.
