Kinsey (State University of New York, Geneseo)Abstract: The Geneseo Nuclear Structure Laboratory operates a 2 MV Van De Graaf accelerator. A LabView data acquisition and control system has been designed and built and is currently monitoring critical accelerator systems. The first part of the project has been completed. A monitor and alarm system that checks the status of the accelerator and accelerator subsystems is operating. The system monitors; the accelerator, the analyzing magnet and diffusion pump coolant temperatures. It also displays the beam line vacuum pressures and accelerator operating parameters such as the corona current, terminal potential, slew rate, upcharge, quadrupole power supplies and NMR magnetic field strength. The monitoring and displays system parameters and notifies users with a series of visual and audible alarms allerting the users of conditions that are beyond allowed limits. The second part of the project is to have the computer intervene when a problem occurs and take action if the user is not present or does not respond to the alarm within a fixed period of time. This part of the projects requires that the computer software be modified to respond to alarms and actuate devices to eliminate the problem. Currently, our hardware has been modified to allow local, remote and computer control of the beam line valves and we are planning to modify vacuum pump hardware to allow similar control. It is our goal to design a system that can ensure the safe operation of the accelerator and react quickly to coolant failures, vacuum breeches, and power outages. |
