Engineering Science students present design work at CERN
The student group is seen here inside the LHC with supervisors John Huber and Clive Siviour, and host Ray Veness of CERN’s Beam Instrumentation Group.The students worked on the design of wire scanner concepts for the Large Hadron Collider. These scanners are devices that monitor the position and cross-section of the hadron beam by rapidly passing a thin wire through the beam and collecting data about the resulting scattering events.
Accurate measurements of the beam position and cross section are crucial for controlling the LHC beam to enable experimentation. However, current designs are unable to scan the LHC beam at its full energy and intensity because the high energy beam can vapourise the wire.
The students proposed novel solutions based on modifying the wire motion both to reduce the time spent in the beam and also to spread the beam intensity along the wire length. As well as enabling scanning of higher intensity particle beams, the designs could also reduce maintenance requirements and so maximise the availability of the LHC for physics.
