DIRECTOR’S NOTES TRIUMF MAGNETS INSTALLED AT LHC very year, TRIUMF has a three-month Eperiod where the accelerators and associated infrastructure undergo extensive maintenance and any planned upgrade. The shutdown period is normally the fi rst three months of the calendar year, but this year, since the regulatory license for the ISAC-II accelerator to send a radioactive beam to an experiment was received at the beginning of January, the shutdown period was delayed to the fourth week of January. This enabled a Shown are six of the 52 Canadian twin-aperture quadrupole magnets two-week running period for MAYA, the fi rst installed in one of the straight “collimation” ISAC-II experiment.
