Title: underground beam transfer line for Bevalac
Description: Two miners started at a pit in the SuperHILAC parking lot and alternately crawled into the liner pipe to dig ahead two feet. Then a hydraulic jack pushed in more pipe, and the process was repeated until 14 ten foot sections had been welded together and pushed into place. The Bevalac link joins the SuperHilac to the Bevatron, allowing the accelerators to work together in a tandem mode known as the Bevalac. The Bevalac began operation on August 1, 1974, and for a long time was the most powerful heavy ion accelerator in the world. In the Bevalac, the Bevatron was linked to the SuperHILAC linear accelerator. Nuclei began their journey in the SuperHILAC and then were passed through a transfer line to the Bevatron, where they were accelerated almost to the speed of light. With the later addition of an improved vacuum system and other modifications, the Bevalac became the only machine the world capable of accelerating all of the elements of the periodic table to relativistic energies. The Bevalac finally ceased operations on February 21, 1993. - JG
