Two Fermilab deflector prototypes being considered for the Project X chopper. In both cases, each rectangular copper plate sets up an electrostatic pulse that kicks the bunch farther and farther away from the beamline, chopping it out. At the recent Project X collaboration meeting, attendees confronted the proposed accelerator’s wide-band chopper, a system that would allow scientists to cherry-pick particle bunches from beams to be routed to multiple experiments. Though its design is a formidable challenge, researchers now believe it’s…

This 4-meter-long quadrupole coil recently achieved the ultimate magnetic-field strength expected for niobium tin coils of this design. This month, scientists are celebrating the centennial of the discovery of superconductivity, a fundamental phenomenon that has made possible the newest achievement in Fermilab’s Technical Division. Shortly before the anniversary, researchers with the laboratory’s High Field Magnet (HFM) program successfully demonstrated optimal performance of a 4-meter-long niobium tin quadrupole coil in the temperature range from 1.9 to 4.6 Kelvin. The achievement is…
