Tests clear way for Big Bang experiment

GENEVA (Reuters) - Tests have cleared the way for the start-up next month of an experiment to restage a mini-version underground of the "Big Bang" which created the universe 15 billion years ago, the project chief said on Monday.

Lyn Evans of the European Organisation for Nuclear Research (CERN) said weekend trials in the vast underground LHC machine in which the particle-smashing experiment will take place over the coming months and years "went without a hitch."

"We look forward to a resounding success when we make our first attempt to send a beam all the way round the LHC," said Evans, who heads the multinational team of scientists that shaped the project and the machine, the Large Hadron Collider.

The final tests involved pumping a single bunch of energy particles from the project's accelerator into the 27-km (17-mile) beam pipe of the collider and steering them counter- clockwise around it for about 3 kms (2 miles).

Earlier in the month a clockwise trial in the LHC -- which runs deep under French and Swiss territory between the Jura mountains and Lake Geneva -- had been equally successful, CERN said.
