【 摘 要 】

A low-{beta} insertion has been designed for the BTeV experiment at C0. With {+-} 12 m for detector space, a {beta}* of 0.5 m can be achieved using 170 T/m magnets in the final focus triplets. A total half-crossing angle of 240 {micro}r is necessary to keep the beams separated by 5{sigma} at the 2nd parasitic crossing. There are 2 possible Tevatron collision scenarios: B0 and D0, but not C0, and; C0, but not B0 or D0.
