-The Electronic Systems Engineering Department of the Computing Division at the Fermi National AcceleratorLaboratory has developed a data acquisition system flexible and powerful enough to meet the needs of a variety of high energy physics applications. The system described in this paper is called CAPTAN (Compact And Programmable daTa Acquisition Node) and its architecture and capabilities are presented in detail here.The three most important characteristics of this system are flexibility, versatility and scalability. These three main features are supported by key architectural features; a vertical bus that permits the user to stack multiple boards, a gigabit Ethernet link that permits high speed communications to the system and the core group of boards that provide specific capabilities for the system.In this paper, we describe the system architecture, give an overview of its capabilities and point out possible applications.

Abstract-The Electronic Systems Engineeri the Computing Division at the Fermi NatiLaboratory has assembled a pixel test beam t energy physics detector research and developm features CMS PSI46 readout chips and a dat control system known as the Compact And Pro Acquisition Node or CAPTAN. The CAPTAN powerful system that meets the readout and con variety of pixel and strip detectors for hig applications. The CAPTAN functions in a network, which facilitates the coordination of planes of the telescope. Through the use hardware, a unified telescope system is attain both the CMS PSI46 pixel components and a This paper discusses results from the telescope mechanical design, alignment procedure, precision.
