Abstract
To reduce activation of the proton synchrotron pole tips and to reduce the ψ -ray background from activated components, the use of marble to line the pole tips is proposed. It has been shown that marble, which is a rather good absorber, is but slightly activated. With the recommended arrangement of marble slabs in the interpolar space of the proton synchrotron, it is expected that the background intensity will be reduced by a factor of three within the chamber and by an order of magnitude in the neighborhood of the chamber.
