“…A single-shot HEDP experiment on a low-repetition rate facility may produce hundreds of gigabytes of raw data [50], while at even modest repetition rates of 1/min., a HRR experiment may collect > 3000 shots in a single experiment day. Even assuming a more modest data rate of 1 GB per shot, such a facility would produce >3 terabytes of data per day.…”

This paper discusses experimental techniques and considerations associated with the transition to high repetition-rate experiments in High Energy Density Physics (HEDP). We particularly highlight approaches to experimentation that become practical only at a threshold of repetition rate. We focus on the transition from operation at several-shots-per-day towards operation in the range of 1/min. to 1 Hz.

“…For example, if 127 I were loaded in the capsule ablator, the 127 I(d, 2n) 127 Xe reaction produces a noble gas that can be collected and quantified using RAGS. If 124 Xe was coloaded with the 127 I, the ratio of the (d, 2n) reactions on the iodine to the 124 Xe(n, 2n) 123 Xe reaction would provide a symmetry and mix diagnostic where the xenon provides both yield normalization and a measure of collection efficiency. The ratio is integrated over the peak burn (width) while uncertainties in energy and space are eliminated.…”

The generation of dynamic high energy density plasmas in the pico-to nanosecond time domain at high-energy laser facilities affords unprecedented nuclear science research possibilities. At the National Ignition Facility (NIF), the primary goal of inertial confinement fusion research has led to the synergistic development of a unique high brightness neutron source, sophisticated nuclear diagnostic instrumentation, and versatile experimental platforms. These novel experimental capabilities provide a new path to investigate nuclear processes and structural effects in the time, mass and energy density domains relevant to astrophysical phenomena in a unique terrestrial environment. Some immediate applications include neutron capture cross-section evaluation, fission fragment production, and ion energy loss measurement in

This participatory action research aimed to develop a database system for the care of elders in the community, Pak Poon sub-district, Nakhon Si Thammarat, Thailand. The key informants were composed of public health officers, community leaders, representatives of the Local Administrative Organization, elders and their families, and lecturers and nursing students of Walailak University. Research instruments included interview questions, an elderly health assessment form, a developed elderly health database system as an experimental tool, and a usability evaluation form. Data collection was conducted by survey, interview, group discussion, and observation. Quantitative data analysis was conducted by frequency distribution and percentage; the validity and reliability of the questionnaire were confirmed with experts for Cronbach’s alpha. The qualitative data revealed content analysis. The results show that the database system consists of, elder health assessment, comprising general information, prior illness and treatment, functionality, mental health risk, risk for fall, and environment, the required features to support achievement of the goal for well-being, consistent with their life style, social capital, and local wisdom. In addition, the database could be used to reduce early risk factors to protect from chronic illness, injury, and decline in physical and psychosocial function. The reporting requirement comprised frequency distribution in terms of capital, problems, and need. Perception of the system and its effectiveness were evaluated using a questionnaire after participants had had an approximately one month period of experience of using the system. The responses to the questionnaire were positive about the system features and system process. From executives and health officers and elders using the database system, it has been improved, based on feedback continuum.
