Gerrit Hörentrup (DESY) | 15 September 2011DESY’s ALPS experiment aims high by searching low, looking for lightweight particles in the low-energy range. The lightweight particles could clue us into the nature of dark matter or dark energy, and ALPS is being upgraded to make more precise measurements than it could before.

Christine Herman (FNAL) | 8 September 2011The halo of an electron beam does not make it angelic. It only adds to the beam's messy profile, making more work for physicists like Jefferson Lab’s Pavel Evtushenko, who was recently awarded funding for five years to look into developing high-range dynamics beam diagnostics that could help clean up electron beams.

Leah Hesla | 1 September 2011Accelerator cavities have their faults, and some pits and cracks hide deep in the walls or in out-of-the-way places where they aren’t easily found. Accelerator researchers help improve flawed cavities by taking their fault-finding missions beneath the cavity surface with X-ray computed tomography.

Leah Hesla | 18 August 2011Being holed up at Fermilab's Test Beam Facility for two weeks, 18 hours a day is no reason to go hungry. Researchers from the University of Texas at Arlington subsisted on instant noodles while they kept busy with their gas electron multipliers, one of the technologies being developed for the ILC detector.

Perrine Royole-Degieux | 4 August 2011The year 2012 will be a crucial one for particle physics. Physicists expect the Large Hadron Collider and astroparticle physics experiments to draw a clearer picture of the field so that, at the end of the year, the CERN Council could vote on an update of the European strategy for particle physics and, in this way, announce Europe’s top priorities for the five years to follow.

Leah Hesla | 28 July 2011Cryomodule 1 at Fermilab is now being powered as a complete, multi-cavity instrument. Scientists will subject it to superconducting radiofrequency tests over the coming weeks.

Leah Hesla | 7 July 2011Keeping accelerating cavities tuned to the right frequency requires continual, gentle hammering by a little device called a piezoelectric tuner. DESY scientists have mastered the art and science of applying the piezo to cavities, bringing them to within several ten-thousandths a percent of the desired frequency.

Rika Takahashi | 23 June 2011As the region around Tohoku University recovers from the March earthquake and regains its footing, scientists there look forward to rejoining ILC research efforts, and the local government highlights the ways recovery could be facilitated by bringing the ILC to Iwate prefecture.

Rika Takahashi | 2 June 2011On 26 May, a first test beam steered through the linac of the Accelerator Test Facility at KEK, Japan, with the same energy as before the March 2011 earthquake. Engineers are now working on the magnet alignment at the beam transportation line.
