This paper presents an approach to analyze the performance of a liquid flat plate collector which is used to raise the temperature of water by utilizing solar radiation. With the help of some basic equation of heat transfer and equations related to calculation of the intensity of solar radiations, the study has been done to determine the rise in temperature of water for domestic and commercial purposes for the Indore region with longitude 77°50' east and latitude 22°44' north of Madhya Pradesh, India. For analysis liquid flat plate collector with 100-litre capacity has been considered and results have been used for further calculation in saving electricity for various months of the year.

The Laser Plasma Division of the Raja Ramanna Centre for Advanced Technology (RRCAT), Indore has been engaged in research and development activities on laser plasma interaction using a 10 TW, 45 fs, Ti:sapphire laser and a variety of in-house developed diagnostic systems for ultrashort laser pulses, plasma, and x-ray radiation. Our recent studies include high order harmonic generation and optimization, laser driven electron acceleration, enhancement of x-ray yield in the water-window spectral region, ultrashort high brightness K-α x-ray generation, and MeV energy bremsstrahlung radiation. This paper briefly describes these studies and the important results obtained. [ABSTRACT FROM AUTHOR]

Indus Synchrotron Radiation complex at Raja Ramanna Centre for Advanced Technology at Indore, India houses two synchrotron radiation sources: Indus-1 and Indus-2 respectively. Indus-1 is a 450 MeV source emitting in VUV and soft x-ray region and operating at 100 mA since 1990 and Indus-2, designed for 2.5 GeV, 300 mA and is currently operating at 2 GeV and 100 mA. Indus-1 has five operational beamlines while Indus-2 has six beamlines installed and operational. Several materials research related problems have been investigated using the reflectivity and photo-electron spectroscopy beamlines at Indus-1 and also the beamlines at Indus-2. Here we will report the current status of both these sources and discuss a few of our studies carried out using these beamlines. [ABSTRACT FROM AUTHOR]
