Common Readout Unit (CRU) - A new readout architecture for the ALICE experiment

PhD Research Work

The ALICE experiment at the CERN Large Hadron Collider (LHC) is presently going for a major upgrade in order to fully exploit the scientific potential of the upcoming high luminosity run, scheduled to start in the year 2021. The high interaction rate and the large event size will result in an experimental data flow of about 3 TB/s from the detectors, which need to be processed before sending to the online computing system and data storage. This processing is done in a dedicated Common Readout Unit (CRU), proposed for data aggregation, trigger and timing distribution and control moderation. It act as common interface between sub-detector electronic systems, computing system and trigger processors. The interface links include GBT, TTC-PON and PCIe. GBT (Gigabit transceiver) is used for detector data payload transmission and fixed latency path for trigger distribution between CRU and detector readout electronics. TTC-PON (Timing, Trigger and Control via Passive Optical Network) is employed for time multiplex trigger distribution between CRU and Central Trigger Processor (CTP). PCIe (Peripheral Component Interconnect Express) is the high-speed serial computer expansion bus standard for bulk data transport between CRU boards and processors.

My PhD work involves firmware development and performance characterization for the CRU hardware at ALICE experiment. As part of the research work I got trained in latest state of the art interfacing standards, like ATCA, PCIe, 10GbE, GBT, and PON. Also got skilled in coding languages like VHDL, Verilog and scripting language like tcl.

DETECTION AND CLASSIFICATION OF CEREBRAL ANEURYSM FROM DIGITAL SUBTRACTION ANGIOGRAM

M.E. Research Work

The Circle of Willis is in the junction of two carotid arteries and two vertebral arteries that supply the brain with nutrition. Junctions where these arteries come together may develop weak spots that can balloon out and fill with blood, creating aneurysms. These sac-like areas may leak or rupture, spilling blood into surrounding tissues which may cause artery spasm leading to potential stroke or even death. Clipping and coiling are two treatment options preferred by neurosurgeon which require proper detection of an aneurysm. Medical practitioners are therefore emphasizing on the prior detection of a cerebral aneurysm (CA) before rupture occurs leading to subarachnoid haemorrhage (SAH). The research work presents two methods by application of those techniques on the image extracted from Digital subtraction angiography (DSA) aids in proper detection of the location, size and type of an aneurysm.

8085 SIMULATOR

B.Tech. Research Work

Understanding of Intel 8085 microprocessor is fundamental to getting insight into the Von-Neumann Architecture. It was first introduced in 1976, since then many generations of computer architecture have come up, some still persists while others are lost in history. This microprocessor still survives because it is still popular in university and training institutes to get students acquainted with basic computer architecture. For this purpose 8085 trainer kit are available on the market. However, with more popular technologies to learn, technical syllabus has very low time bandwidth available for this topic. All that is necessary for the students is to understand the functional working model of this basic architecture and then proceed on to next advance level of the subject. With this academic learning purpose in mind this simulator software is designed. It helps in get started easily with example codes, and to learn the architecture playfully. It also provides a trainer kit as an appealing functional alternative to real hardware. The users can write assembly code easily and get results quickly without even having the actual hardware.
