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.
