  In this contribution, I present some of the new beam diagnostic and monitoring tools developed by the MAX IV Operations Group. In particular, new BPM and accelerator tunes visualization tools and other simple but useful applications we have developed, such as our RF System Monitor, are presented. I also briefly share our experience with the development of audible alarms, which help operators monitor various parameters of the machine and explain how the implementation of all these tools have improved accelerator operations at MAX IV.

The beamline sections of an accelerator and different ion sources require a vacuum system capable of providing pressures down to 10-10 Torr. To control, monitor, and provide interlock protection of the vacuum equipment, a PLC-based vacuum control system was developed and tested at the Argonne Tandem Linear Accelerator (ATLAS). This system was designed to be highly flexible and scalable to meet the variety of equipment and configurations at ATLAS. The current FGPA-based system is reliable and fast, but is very difficult to maintain and upgrade. Particular attention was paid to the signal distribution to promote standard cable connections, minimize the usage of terminal blocks, and reduce the time to troubleshoot problematic channels. The system monitors the status of fast acting relays for interlock or control purposes, and utilizes RS-485 communication to gather lower priority information such as pump speeds or vacuum pressure readouts. The vacuum levels are monitored to interlock the high voltages of some beam instruments to protect against sparks as the Paschen minimum is approached. This paper mainly presents work on hardware interface to various vacuum devices.
