Kolkata scientists gear up for more projects at CERN

From the Times of India:  Kolkata scientists gear up for more projects at CERN

KOLKATA: With the Large Hadron Collider (LHC) set to be shut down for two years from February 2013 for upgrade and maintenance, the city-based Saha Institute of Nuclear Physics (SINP) and the Variable Energy Cyclotron Centre (VECC) are readying for greater participation over newer experiments at the European Organization for Nuclear Research (CERN).

"SINP will be more actively associated with CERN for five more years for three experiments - ALICE, CMS and ISOLDE. We shall increase the exchange of faculty and students for these experiments," said SINP director Milan Kumar Sanyal while interacting with journalists on Tuesday.

Rolf-Dieter Heuer, director-general of CERN, and Rudiger Voss, international relations in-charge at CERN, were also present at the press conference.

"We shall increase the number of students involved in the experiments. As part of the current five-year plan, we are also getting involved in the upgrade and maintenance of experiments SINP was involved in," added Sanyal, indicating that the discussions with the director-general of CERN were quite satisfying.
"We welcome more participation from Indian scientists. If India becomes an associate member of CERN, all the offshoots of technology can be used here without any riders," said Heuer.

"We have a 20-years programme with the LHC. Scientists in Europe will sit together to decide on the particular subject in particle physics that will be researched on as the next step after LHC," added Heuer.

VECC scientists also held a series of meeting with officials of CERN, including Heuer and Voss, to discuss the role of the Kokata-based institute in the ALICE upgrade projects and data analysis of collision, which will be accumulated till February 2013. After that, LHC will be shut down for two years for upgrade and maintenance.
"We discussed VECC's plans regarding the maintenance and refurbishing of Photon Multiplicity Detector (PMD) for the ALICE experiment. The PMD will be examined and we shall make changes in hardware if the need arises," said Dinesh Kumar Srivastava, director of VECC, mentioning that the institute had been involved with CERN since 1989.

"We also discussed the researches conducted till date regarding the installation of another advanced detector beside the PMD for the ALICE experiment and the letter of intent has already been sent to the authorities at CERN," added Srivastava.

"It is called FoCal - Forward Calorimeter - and the cost is around 10million Swiss francs. India, Japan, The Netherlands, USA and Czeck Republic are partnering in the project. We are mainly trying to develop silicon detectors for it," said Tapan Nayek, senior scientist at VECC.

"In the meantime, our next work will be to analyse the huge data collected from the collisions at LHC," explained Premomoy Ghosh, senior scientist at VECC.
