Class Dsc2Scaler

java.lang.Object

org.jlab.detector.scalers.DaqScaler

org.jlab.detector.scalers.Dsc2Scaler

public class Dsc2Scaler
extends DaqScaler

The DSC2 is a JLab-designed discriminator board with 2 thresholds, called TDC and TRG, with independent outputs, both gated and ungated, and corresponding VME-readable scalers. The CLAS12 DAQ uses this board to periodically readout run-integrated scalers like the Faraday cup and SLM, for the purposes of total beam-charge measurements, and that's what this class is geared towards.

public Dsc2Scaler(org.jlab.jnp.hipo4.data.Bank bank,
 org.jlab.utils.groups.IndexedTable fcupTable,
 org.jlab.utils.groups.IndexedTable slmTable,

slmTable - /runcontrol/slm CCDB table

seconds - dwell time, provided in case the clock rolls over

Dsc2Scaler

 org.jlab.utils.groups.IndexedTable fcupTable,
 org.jlab.utils.groups.IndexedTable slmTable,
 org.jlab.utils.groups.IndexedTable dscTable)

Parameters:

bank - RAW::scaler bank

fcupTable - /runcontrol/fcup CCDB table

slmTable - /runcontrol/slm CCDB table

dscTable - /daq/config/scalers/dsc1 CCDB table

Method Details

calibrate

protected final void calibrate(org.jlab.utils.groups.IndexedTable fcupTable,
 org.jlab.utils.groups.IndexedTable slmTable,
 double seconds)

During some run periods, the run-integrating DSC2 scaler's clock frequency was too large and rolls over during the run. So here we can pass in seconds (e.g. based on RCDB run start time) instead.

Parameters:

fcupTable - /runcontrol/fcup CCDB table

slmTable - /runcontrol/slm CCDB table

seconds -

read

public final void read(org.jlab.jnp.hipo4.data.Bank bank)

Parameters:

bank -
