ISLAMABAD - The young scientists from Pakistan who participated in 'Big Bang' experiment on September 10 would bring new techniques and experience with them that would be used in the country. Dr Riazud Din, the student of Late Professor Abdus Salam and the first DG of National Centre for Physics (NCP), stated this while briefing media persons here on Tuesday. The briefing was held to highlight the contributions of Pakistani scientists and engineers to CERN, the European organisation for nuclear research on Swiss-French border, and for that enormous experiment that created the universe 13.7 billion years ago. Dr Riazud Din informed that as many as 15 physicists, 10 engineers, 5 lasers and Opto-electronics experts, 6 computer professionals and 6 students from NCP and Pakistan Atomic Energy Commission (PAEC) were involved in the experiment among other thousands of scientists of the world. CERN has provided an environment to Pakistani scientists and engineers to work in cutting edge technology, which is the only way to access that technology in the present scenario, said Badar Suleman, DG, PAEC. "PAEC personnel received extensive exposure to good technical practices who worked on various problems. PAEC brought in some very valuable inputs during the design phase in CMS detector." The activity in which these people were involved was the construction of components of Compact Muon Soleniod(CMS) detector, which consisted of assembling and testing of 288 Resistive Plate Chambers (RPS's) with 46,000 channels involving front-end electronics. They also participated in physics analysis involving advanced computing for CMS data production and infrastructure for LHC Computing Grid (LCG) Node at NCP, fabrication of mechanical pieces for LHC at a cost much less than the European cost, design of Tracker Alignment and other opto-electronic related work for the CMS. It was also disclosed that PAEC assembled carbon frames for the detector outer barrel at a cost, which was approximately a third of the European cost. The parts are sent to from CERN, assembled in Pakistan and are sent to Fermi Lab, USA, which added the front-end electronics and chipped them to CERN for final integration into rods. In recognition of PAEC's contribution, quality of work and adherence to schedule, in 2006, CERN awarded PAEC Best Supplier Awards. Dr Riaz said the relationship of Pakistan with CERN, one of the outstanding high-energy physics laboratories in the world, went back to 1973, which provided the first and crucial evidence of unification through experiments done at CERN.
