| Abstract | Since Roentgen discovered X-rays, X-rays have been widely used in medical diagnosis and industrial non-destructive testing. With the improvement of the performance of aviation technology and instrumentation, higher requirements have been set for the calibration of detectors. X-ray machine performance is very important for calibration. Tube voltage, tube current, and inherent filtration are important parameters of the X-ray machine and directly affect the image imaging quality and radiation dose. Here, the voltage performance of the X-ray machine was measured using HPGe detector. Measure the tube voltage of the X-ray machine using the end of the spectrum method, it is shown that the performance of the X-ray machine shows the tube voltage within ±2%. Measurement of the linearity of the X-ray tube current and current stability using the PTW30013 ionisation chamber. The relative deviation of the actual measured tube current is 0.08%. The inherent filtration of the X-ray machine was measured by the half-value layer method, and the inherent filtration was 0.058 mm Al. The inherent filtration of the K-fluorescent device was measured to be 1.487 mm Al. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
