This project is a multi-institutional Cluster project for the development of system-on-chip (SOC) Platform for secure speech communication involving CSIR-CEERI, IIT Jodhpur, NITKurukshetra, NIT-Hamirpur, ABV-IIITM Gwalior and TU-Patiala. It is part of DeitY/MCIT sponsored Special Manpower Development Programme for VLSI Design and Related Software for Chips-to-System Design (SMDP-C2SD). CSIR-CEERI is the Programme Coordinating Institute that covers [...]

The MEMS-based accelerometer is extensively used in applications like automobile, avionics, etc. One system comprising of an accelerometer and its interface circuit were developed. An analog interface circuit has been developed for piezo-resistive MEMS accelerometer for application in Micro Air Vehicle (MAV). The system specifications were provided by CSIR-NAL. The designed circuit in the form of [...]

CSIR-CEERI has been engaged in the design and development of a 6 MW peak, 24 kW average power S-band Klystron with financial support from Bhabha Atomic Research Centre (BARC), Mumbai. The Klystron would be used as high power RF source for 10 MeV Industrial Linear Accelerator, which is under development at BARC. One of the primary [...]

An RF coupler fabricated at CSIR-CEERI for the indigenously developed Indus-2 RF cavity at RRCAT, Indore has qualified the high power RF testing conducted during November- December, 2015. The high-power RF coupler has been brazed entirely at CSIR-CEERI and it has been able to transfer 35 kW of CW RF power into the Indus-2 RF cavity. [...]

A Beam Stick Tube which consists of the electron gun and collector suitable for use in actual klystron has been tested to evaluate electron beam transmission characteristics in presence of focusing magnetic field (Fig. 1). The desired beam transmission characteristics have been achieved. The RF cavity having a resonant frequency of 352.2 MHz has been cold [...]

As a precursor to the klystron development, a Gun Collector Test Module (GCTM) was developed and tested with pulsed supply. The measured perveance of the electron gun is in close agreement with the design value. The RF cavity with input coupler and tuning arrangement has been developed (Fig. 1). One intermediate cavity with a tuner has [...]

The first complete prototype was integrated as shown in Fig. 1. In addition, two electron gun assemblies, one set of RF sections, loss coating on APBN rods, helix-rod bundle, set of RF couplers and one multi-stage depressed collector were developed and characterised.

The design of W-band folded waveguide TWT was completed. Two numbers of leak tight gun stacks, one collector assembly and one rectangular block with 600-micron beam hole were fabricated. One beam stick tube with electron gun stack, rectangular block and collector were integrated to optimise the process of axially aligned integration within 5 micron with leak [...]
