A double crystal based moderate resolution small-angle neutron scattering instrument has been built and commissioned at the guide tube laboratory of Dhruva reactor, Bhabha Atomic Research Centre, Trombay, India. The instrument consists of a non-dispersive ( I , -1) setting of 11 1 reflections of silicon single crystals with sample between the two crystals. The neutron wavelength used is 0.312nm. The analyser crystal rotates with smallest step size of 0.0012". At 65 MW of reactor power, the peak count rate of the blank rocking curve is about 55 counts per second at the detector position and the ratio of integrated signal to integrated noise is 450 for a typical experiment with sintered alumina. Experiments with sintered alumina specimens reveal that the accessible range of wave vector transfer q is 0.003-0.173nm-1. The instrument is calibrated with respect to the high resolution ultra small-angle neutron scattering instrument S18 at the Institute Laue-Langevin in Grenoble, France.

Pandemics like COVID-19 poses several challenges which not only include medical but also have a psycho-social impact on the society. It is important to understand how public appraise a pandemic in a large country like India and how do they mentally and behaviorally respond during this threat. A structured questionnaire was used to collect the data and examine the Health Anxiety, Coping and Locus of Control-Internal/External variables using five-point Likert Scale. Responses (n = 231 ) were collected during 24th March to 30th March; this duration is part of nation-wide lockdown period. There was a significant difference between various age groups and their Health Anxiety. (F (8, 222)=2.772. p<.05). Analysis of health related anxiety reveals that respondents are more worried over the health of their loved ones than theirs. With regard to coping mechanism, it was found that, during the Covid-19 outbreak period, respondents displayed high engagement with the social media and connect with their loved ones using technology. Respondents feel responsible towards disease control, prevention, spread and healthy protective behaviour. The study provides preliminary insights into people’s perception on Health Anxiety, Locus of Control and Coping mechanism.
