| Abstract | Silicon photomultiplier (SiPM) with bulk quenching resistor is one of the main SiPM technologies now under researches and developments. The device was first demonstrated at the Novel Device Laboratory (NDL). It has advantages of high micro cell density, short recovery time and has potential to alleviate the conflict between the high photon detection efficiency (PDE) and large dynamic range encountered by conventional SiPM, and it is beneficial to be applied in HEP calorimeters, PET, scintillator readout, radiation monitors and spectroscopy analysis, where high space resolution, large dynamic range and adequate high PDE are mandatory needed simultaneously. In the past years, with the optimization of the fabrication technology and structure of the device, the active area of the device has been increased from 1 mm × 1 mm to 2.2 mm × 2.2 mm, the peak PDE has been increased from 8% to 13%, while the density of the micro cells remains as large as $9000/mm^{2}$ and the recovery time remains to as low as ~5ns. Application of the device to the detection of natural background radiation by using a lutetium orthosilicate (LSO) scintillator has been performed. Energy resolution of 1-to-1 coupling of this device and a 2 mm × 2 mm × 10 mm lutetium yttrium oxyorthosilicate (LYSO) crystal yielded an energy resolution of 11.8% by using radiation sources of $^{137}Cs$ (662keV photons) without any high speed preamplifiers. These latest developments of SiPM with bulk quenching resistor will be presented in this record. |

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.
