CAMAC instrumentation in an HP/1000 environment
Experimental environments often have very diverse and demanding data acquisition requirements. This paper describes how we have expanded our HP data acquisition computer system to include the CAMAC standard of instrumentation and interface. A brief description of the CAMAC standard will be presented followed by hardware and software implementation details of the CAMAC standard on HP computers. We have chosen to implement this standard using a commercially available crate controller and our own software package. The CAMAC software library allows the user to perform all the basic CAMAC functions as well as transfer data to and from CAMAC modules in a number of different modes. Details of this library will be presented including manipulation of the crate controller and error handling. I/O performance of the MARS system using this library will also be presented. Included will be a list of published literature concerning the standard and a list of CAMAC equipment suppliers. This paper will introduce the HP 1000 computer user to the CAMAC standard of instrumentation and show how the MARS experiment at Lawrence Livermore National Laboratory has implemented this standard.
