  Recent developments in the field of accelerator-domain and computer-domain modelling have led to a better understanding of the "art" of control system specification and design. It now appears possible to "compile" a control system specification to produce the architectural design. The information required by the "compiler" is discussed and one hardware optimization algo­rithm presented. The desired characteristics of !he hardware and software components of a distributed control system architecture are discussed and the shortcomings of some commercial products.

  A 92 MHz auxiliary accelerating cavity has been designed for installation inside the 1RIUMF cyclotron, operating up to a maximum peak voltage of 200 kV. The cavity doubles the energy gain per turn for accelerating hydrogen ions in the energy region of 400-500 MeV, and reduces by 50 % the stripping loss of the ion beam. The control system for the booster comprises a PC-based processor in a VME crate, for local control, and a 68030 processor with an Ethernet connection as the interface to the TRIUMF Central Control System. The requirements for the booster control system were established by an object-oriented requirements analysis. Afterward, an object-oriented architectural design step was used to produce the processor allocation of the design, which was then implemented using C, for the VME processor, and a commercial database and screen generator product, for the VAX user interface.
