Data

Arrival time data

The data in the time stamped ROOT files include the beam arrival time stored in the branch Conversion.arrivalTime as TArrayF. All events can be chained to get the contiuous beam arrival time stream.

In addition the delay stage position and temperature inside the BAM box is stored in BAMData.root:

• DAQCollector.motor.actualValue: Delay stage motor position in steps
• DAQCollector.motor.encoder: Delay stage motor encoder readback
• DAQCollector.temperature.t1/t2: Temperature measured inside the BAM box

Low level RF performance measurements

The *.dat files includes measurements of the additive noise (phase noise and amplitude modulation) measuered with an FSWP. The measurements were done by using the ELBE MO reference and the cavity probe signals of cavity LA2-RC01 (C3) and LA2-RC11 (C4).
