The CDF detector prepares for Run II
Within the next few weeks, the CDF (Collider Detector at Fermilab) will start once again to record proton-antiproton collisions at the world's high energy particle accelerator, the Tevatron at the Fermi National Accelerator Laboratory in the US. In 1995 CDF and is "sister" detector D0 discovered the top quark - the heaviest of nature's building blocks. Since 1997 the two detectors have been undergoing major refurbishment in preparation for higher energy collisions in the Tevatron, at 20 times the previous rate. These improvements are due to the construction of a new Main Injector to provide the particle beams for the Tevatron. CDF has built a new silicon vertex detector - this is the core of the detector which pin-points new particles close to their production in the collisions at the centre. The new detector, being installed in the image here, will allow CDF to make even more precise measurements than before, and to search for new phenomena - including the Higgs particle - during the Tevatron's imminent Run II.
