The question has been raised concerning where to put lead shielding to reduce the synchrotron radiation dose to the electronics in the alcoves. Assuming that the alcoves are not near a collimator, the dominant radiation source is synchrotron radiation. Previous calculations indicate that a one-centimeter-thick lead door on the alcove would provide sufficient shielding. It was proposed that a one-half-inch-thick lead door be used (the next available thickness). The door would be roughly 36 square ft and weigh 1150 lbs. The alternative would be to shield the transport line, i.e., the open side of the magnets and the gaps between the magnets. We have done some further calculations concerning the possibilities of shielding the transport lines instead of the alcove. The point of contention in previous discussions is whether synchrotron radiation propagates as a gas down the tunnel or whether it is attenuated rapidly.
