MWA and ORT
3. Halos and Relics in Galaxy Clusters GMRT and MWA
50 MHz system for GMRT
4. Multi-frequency observations of Compact objects ,
MWA is a low-frequency imaging radio interferometer facility being built in the radio-quiet area of Western Australia
MWA-LFD Kick-Off June 2006
Each receiver receives outputs from 8 tiles , digitize them, do 512 CH PFB and send them through fiber links after serializing.
i) A/D and Filter Bank (ADFB) Architecture
ii) Firmware for ADFB board
i) Backplane and
ii) Clock for 32 T digital receiver
i) Hardware and firmware architecture for AGFO
ii) Design of Board and firmware development
Challenges for MWA, LOFAR, GMRT, Global Signal Detection Experiments are same
The screen is made resistive to ensure required phase diff. between transmitted and reflected signals exists and has equal transmission and reflected signals
Take it to a radio quite zone
The development of a Thomson polarimeter including
proportional counter detectors,
associated front-end electronics,
event processing logic,
data acquisition system, and
test and calibration system
have been completed successfully.
Engineering Model is being developed
