The Spallation Neutron Source (SNS) is a partnership between six DOE Labs. Lawrence Berkeley National Laboratory (LBNL) is responsible for the Front End. To ensure a truly intergrated controls system, many standards have been agreed upon, including the use of EPICS as the basic toolkit. However, unique within the partnership is the requirement for LBNL to operate the complete Front End locally before shipping it to the ORNL site. Thus, its control system must be finished in 2001, well before the SNS completion date of 2006. Consequently many decisions regarding interface hardware, operator screen layout, VME equipment types, and so forth had to be made before the other five partners had completed their designs. In some cases the Front End has defined a standard by default. In others an upgrade to a new standard is anticipated by ORNL later. >From the beginning, all Front End devices have been commissioned with the EPICS control system. Of the approximately 1500 signals required, about 30% are now under daily operational use. This paper will discuss some unique interface requirements that led to adding new device families into the EPICS repertoire. It will also describe the choices and trade-offs made for all major areas.
