The cryogenic control software for the GeN target
runs on an VME-based MVE162-232
input-output computer (IOC) located in the Hall, on the
target platform. The computer name is VMEC4 (129.57.168.104).
The operating system for the IOC is VxWorks, and the
EPICS software must be loaded onto the IOC each time
it is rebooted. This is an automatic process, and is performed
from the JLab Accelerator server, OPServ. The boot
directory is /cs/op/iocs/vmec4.
Additional information can be found online
at http://devweb.acc.jlab.org/internal/llapps/hcptarg/0.html.
Most of the data acquisition and communication is performed with the
use of several GreenSpring Industry Packs (IPs) mounted on the IOC
board itself, or on an IP carrier board (see table below).
The JT valves are controlled by a JLab constructed VME card,
labelled ``IO-Flex''.
