Limit on beam radius, based on
RHIC/AP25, S. Tepikian, April 1994

First check calculation against Fig.9

Guess this means at intersection

OK this agrees with Fig. 9

Now compare with Fig. 7

again looks like fig. 7

Verified (9/30/03) with Steve Tepikian that when they say 10 x s they are referring to the beam pipe radius and that the injection numbers below are correct. He said 10 x s is comfortable and the lower limit is 6 x s

Lowest limit for beam pipe radius:
