LANSCE Controls Computer Hardware

Moving from Sun Microsystems to “commodity” PCs running Linux (e.g. RHEL)» They want to say good-bye to the Vax workstations as

well

Move Front-End-Processors to VME-CAMAC, VME, and PLC-etherIp» Good-bye to the micro-Vax» When all of this is done the CA/Vax-gateways will no

longer be needed. Pure EPICS is where they are headed.

LANSCE Controls Software

Standardize on java for most of the high-level applications. There will still be TCL/TK apps running around as well.» They are very interested in XAL and plan to use it. This

is something we pull from CVS before I left.

Stay with edd/dm for now. Let’s see what EPICS Office is going to do.

Move to Channel Archiver data collection and retrieval software

vxWorks 6.X (PowerPC targets)

LANSCE uses shared Captive accounts.» This helps make a consistent and stable environment

for the operators» The shared accounts are easy to manage.
