Abstract: Time walk is one of the major issues associated with leading edge triggering techniques when used to measure the signal of varying pulse height. In this article, we are exploring the use of discrete analog front end design based on monolithic microwave transistor amplifier IC(MMIC) and constant fraction discriminator for resistive plate chamber detectors.

TL;DR: In this paper, an 8-channel amplifier and discriminator chip has been developed to exploit the excellent timing properties of the multigap resistive plate chamber (MRPC), which is fabricated with 0.25 μ m CMOS technology.
Abstract: For the full exploitation of the excellent timing properties of the Multigap Resistive Plate Chamber (MRPC), front-end electronics with special characteristics are needed. These are (a) differential input, to profit from the differential signal from the MRPC (b) a fast amplifier with less than 1 ns peaking time and (c) input charge measurement by Time-Over-Threshold for slewing correction. An 8-channel amplifier and discriminator chip has been developed to match these requirements. This is the NINO ASIC, fabricated with 0.25 μ m CMOS technology. The power requirement at 40 mW/channel is low. Results on the performance of the MRPCs using the NINO ASIC are presented. Typical time resolution σ of the MRPC system is in the 50 ps range, with an efficiency of 99.9 % .

TL;DR: In order to revive underground neutrino experiments in India, a multi-institutional collaboration has been formed with the objective of creating an India-based Neutrino Observatory (INO), which has decided to build a magnetized Iron CALorimeter (ICAL) detector with Resistive Plate Chambers (RPCs) as the active detector elements.
Abstract: Important developments have occurred recently in neutrino physics and neutrino astronomy. Oscillations of neutrinos, and the inferred evidence that neutrinos have mass, are likely to have far-reaching consequences. This discovery has come from the study of neutrinos from the Sun and those produced in interactions of cosmic rays with the earth’s atmosphere. The pioneering Homestake Mine Neutrino Experiment in the USA, the gigantic Super-Kamiokande detector and the KamLAND detector in Japan, the heavy-water detector at the Sudbury Neutrino Observatory in Canada, and a few other laboratories, together, have contributed in a very fundamental way to our knowledge of neutrino properties and interactions. Impelled by these discoveries and their implications for the future of particle physics, plans have been made world-wide, for new neutrino detectors, neutrino factories and long base-line neutrino experiments. Indian scientists were pioneers in atmospheric neutrino experiments. In fact, neutrinos produced by cosmic ray interactions in the earth’s atmosphere were first detected in the deep mines of the Kolar Gold Fields (KGF) in south India in 1965. In order to revive underground neutrino experiments in India, a multi-institutional collaboration has been formed with the objective of creating an India-based Neutrino Observatory (INO). Considering the physics possibilities and given the past experience at KGF, the INO collaboration has decided to build a magnetised Iron CALorimeter (ICAL) detector with Resistive Plate Chambers (RPCs) as the active detector elements. In the first phase of its operation, ICAL will be used for atmospheric neutrino physics with the aim of making precision measurements of the parameters related to neutrino oscillations. The detector will be magnetised to a field of about 1.3 T, enabling it to distinguish the positive and negative muons and thus identifying muon-type neutrino and anti-neutrino produced events separately. This will be useful for ICAL to provide an exciting possibility to determine the ordering of the neutrino mass levels. Finally, this detector can also be used as the far-detector of a futuristic long-base-line neutrino experiment
