“…One such application [64] uses Firewire for distributed data acquisition in Relativistic Heavy Ion Collider (RHIC) beam position monitoring. All this formed a sophisticated control system, with four independent Firewire position monitoring devices connected to each of several VMEbus control systems.…”

The objective of this paper is to present a historical overview of design choices for data acquisition and control systems, from the first developments in CAMAC, through the evolution of their designs operating in VMEbus, Firewire and USB, to the latest developments concerning distributed systems using, in particular, wireless protocols and time-triggered architecture. First part of the overview is focused on connectivity aspects, including buses and interconnects, as well as their standardization. More sophisticated designs and a number of challenges are addressed in the second part, among them: bus performance, bus safety and security, and others.

“…Each analog sampler resides on a circuit board that also contains the data acquisition hardware. Each board includes two 16-bit digitizers, a fixed point digital signal processor (DSP) subsystem, an in-system programmable gate array, a beam synchronous timing interface, and an IEEE1394 Serial Bus (Firewire) interface (15). Two boards are packaged together in each module, but each board functions as a completely independent position channel.…”

The Relativistic Heavy Ion Collider (RHIC) consists of two 3.8 km circumference rings utilizing 396 superconducting dipoles and 492 superconducting quadrupoles. Each ring will accelerate approximately 60 bunches of 10 11 protons to 250 GeV, or 10 9 fully stripped gold ions to 100 GeV/nucleon. Commissioning is scheduled for early 1999 with detectors for some of the 6 intersection regions scheduled for initial operation later in the year. The injection line instrumentation includes: 52 beam position monitor (BPM) channels, 56 beam loss monitor (BLM) channels, 5 fast integrating current transformers and 12 video beam profile monitors. The collider ring instrumentation includes: 667 BPM channels, 400 BLM channels, wall current monitors, DC current transformers, ionization profile monitors (IPMs), transverse feedback systems, and resonant Schottky monitors. The use of superconducting magnets affected the beam instrumentation design. The BPM electrodes must function in a cryogenic environment and the BLM system must prevent magnet quenches from either fast or slow losses with widely different rates. RHIC is the first superconducting accelerator to cross transition, requiring close monitoring of beam parameters at this time. High space-charge due to the fully stripped gold ions required the IPM to collect magnetically guided electrons rather than the conventional ions. Since polarized beams will also be accelerated in RHIC, additional constraints were put on the instrumentation. The orbit must be well controlled to minimize depolarizing resonance strengths. Also, the position monitors must accommodate large orbit displacements within the Siberian snakes and spin rotators. The design of the instrumentation will be presented along with results obtained during bench tests, the injection line commissioning, and the first sextant test. OVERVIEW OF RHIC Upon completion in 1999, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will accelerate and collide protons, polarized protons, and heavy ions (1) (2). Heavy ion collisions up to Gold on Gold at 100 GeV/u beam energies will produce extended nuclear matter with energy densities an order of magnitude greater than that of the nuclear ground state. This should result in temperatures and matter densities that prevailed a few microseconds after the origin of the universe. It is also believed that these extreme conditions could produce a phase transition to a quark-gluon plasma. The Spin Physics program at RHIC will utilize polarized protons at up to 250 GeV and 70% polarization. The primary goal is to study the spin structure function of the proton. The collider consists of two rings separated horizontally by 90 cm in a tunnel 3.834 km in circumference. Collision points are provided in six insertion regions that are connected by six arcs. The total complement of magnets for both rings include 288 arc dipoles, 276 arc quadrupoles, 108 insertion dipoles, and 216 insertion quadrupoles. Additional magnets include 72 trim quadrupoles, 288 sextupoles, and 492...

The TMO (Time-triggered Message-triggered Object) model is a well-known real-time object model for distributed timeliness computing. In a couple of years ago, we developed a Linux-based real-time kernel, named TMO-Linux, supporting deadline driven executions of TMO's. TMO-Linux and its distributed IPC subsystem have been used well in developing networked control systems consisting of cooperating embedded devices, but there have difficulties in executing some TMO applications accurately due to the lack of timeliness in distributed communications. To overcome this problem, we newly developed a real-time distributed IPC over IEEE1394 for the TMO-Linux kernel. In the new system, predictable delivery services for real-time messages are provided by isochronous transmissions of IEEE1394. To implement predictable delivery services, each node is set to have its own isochronous channel for receiving data that is allocated to a fixed time-slot bandwidth in an IEEE1394 frame.This paper presents an implementation technique for the IEEE1394-based real-time distributed IPC and collaborations of computing nodes using TMO-Linux.
