What devices can I acquire "beam synchronous" and what is their PV name?

Question

​What devices can I acquire "beam synchronous" and what is their PV name?

Answer

At FACET, we can acquire data on a pulse-by-pulse basis from multiple devices. These devices are specially set up with hardware that allows us to tag the data with a unique pulse id that means that we can collect the data in the DAQ and guarantee that the data collected for a specific pulse really is all related to the same pulse.

 
Not all devices in the FACET controls system is set up such that this is possible. If the device doesn't have an "event receiver", which is a particular piece of hardware, then it is not possible to get pulse-by-pulse, id tagged data. These devices are often things like pressure gauge controllers and temperature sensors where pulse by pulse information isn't useful anyway.
 
Devices that are available on a pulse-by-pulse basis tend to be camera images and ADCs. A full list of devices (except for cameras) that can be acquired this way is available here:
 
The "root_name" relates to the nomenclature used in the control system. For a handy guide to what these mean in a practical sense, you can compare it to the device map:

 

Please note that if you are not getting data on a pulse by pulse basis with BSA, this is a problem that should be reported. It may indicate a hardware failure.
