Flexibility in Accelerator Housings

Flexibility in the design of Accelerator Housings is achieved by: 1. Proper site selection and planning; 2. Study of critical areas of design; 3. Proper selection of shielding materials; 4. Maximum use of non specialized spaces; 5. Correct selection of crane capacity and coverage; 6. Location of offices, laboratories and utilities to facilitate expansion; and 7. Provision of adequate space for counting room expansion. Proposals are presented for building construction techniques and arrangements that facilitate future expansion and modification of an accelerator housing. Recommendations are presented for shielding techniques which permit flexibility. Relationships between flexibility and cost are discussed for both building and shielding construction.
