Achromat The concrete girders, or cells, in the SLC arcs are called 'achromats' because their magnetic optics are designed to be achromatic. A beam line is called achromatic when its beam transport characteristics do not change momentum. For convenience of construction and operation, the arcs are divided into 23 subsections, each made up of 20 magnets. Each subsection is called an achromat.

APIARY An early ACROnymn for the B Factory. Alper Garren, an LBL accelerator physicist who first designed the lattice for what is now referred to as PEP-II, or the B Factory, coined the phrase 'Asymmetric Particle Interactions Accelerator Research Yard.' Pier Oddone at LBL used an alternate version that captured the physicist's perspective of the high luminosity: 'Asymmetric Particle Interactions At Roaring Yield.'

Arc One of the two curved, caliper-shaped transport lines of the SLC which transport the two beams from the switchyard to the final focus area for collision. Since the arcs are curved and without klystron accelerator stations, about two GeV of beam energy is lost in each arc. See also Achromat.
