The low density of beryllium allows collision products to reach the surrounding detectors without significant interaction, its stiffness allows a powerful vacuum to be produced within the pipe to minimize interaction with gases, its thermal stability allows it to function correctly at temperatures of only a few degrees above absolute zero , and its diamagnetic nature keeps it from interfering with the complex multipole magnet systems used to steer and focus the particle beams.
