Highly unlikely that the machine will attract any form of extraterrestrial beings. If anything the planet would attract said hostile beings rather than it's technology
the hadron collider has a diameter of 3.8 metres and has a circumference of 17 miles (27 kilometres)
No you can find updates on the Large Hadron Collider's (LHC) progress at the link below.
CERN's Large Hadron Collider has been repaired and is in full operation. (January 2012)
No. As far as is known there are no aliens. The large hadron collider is a research tool, not a weapon.
The Large Hadron Collider (LHC) weighs approximately 38,000 tonnes, which is equivalent to about 84 million pounds.
We don't know, but probably not. Questions like this are the sorts of things that the Large Hadron Collider (LHC) were designed to discover. But don't worry; any such mini-black holes would be below the Hawking size limit, and would "evaporate" through Hawking Radiation.
