Multichannel Scaler Quick Scans
- Uses an MCS to rapidly collect thousands of data
points during a continuous scan of one or more motors.
- Can take data around 50 to 100 times faster than a traditional step scan.
- Uses the EPICS MCA record to control Struck or SIS multichannel scalers.
- The scans are implemented using a generic MX MCS device class, so they
could be used with future alternate MX MCS record types.
- Intended to be used in combination with motor encoders, but can operate
with reduced functionality without encoders.
- Ultimately, most MX motor drivers will support quick scanning as well as
single axis pseudomotors such as energy.
MCS-related Record Types
- MCS Scaler - Uses a single MCS channel as a standard MX scaler
either for quick scans or step scans.
- MCS Timer - Uses the MCS timer as a standard MX timer either
for quick scans or step scans.
- MCS multichannel encoder - Uses a pair of MCS channels as
buffers to record motor encoder pulses for quick scans.
- APS ID quick scan - A variant of the MCS quick scan that includes
a synchronous scan of the undulator gap.
