OP Monitoring How To

This page aims to point out common pitfalls/operating procedures that may be encountered whilst operating the various monitoring tools in the CCC. This is meant to focus primarily on beam observation tools (BBQ, FBCT, Headtail monitor etc.) but may also cover other useful tools such as vacuum monitoring.

Headtail Monitor

This is a device for measuring the transverse displacement of the beam. It is capable of measuring short time resolutions over arbitrarily (to within memory limitations) time periods. Further details can be found here (presentation to ICE section by B. Salvant).

Some pitfalls

• Auto-save must be active for data to be read! See image below
• A screenshot illustrating the autosave check box in the headtail monitor application:
  

• Note it is not known whether it is possible to read the vertical and horizontal headtail monitors for one beam at the same time. If you wish to try, please do so.
• Each monitor will require a new instance of the application to be opened. There is no known limit to the number of simultaneous instances. Only one instance may read any one channel at a time. i.e. two different instances may not both read the horizontal beam 1 channel at the same time.
• If the beam is dumped during an acquisition there is a chance that the time stamp on the saved file will be incorrect.
