Variations

These are interesting variations related to the CDC:

  • CDC_8mm_0T, CDC_9mm_0T, CDC_10mm_0T - versions of time-distance tables for different sized straws, no magnetic field. only 25 tables generated, with mixtures of 47/53 to 53/47 of Ar/CO2, in 0.25% increments.

Tables

CDC/timing_offsets

1-3522 timing offset, t0 (ns)

CDC/wire_gains

1-3522 gain correction factor

CDC/wire_alignment (3522 rows)

dxu upstream wire end displacement - X
dyu upstream wire end displacement - Y
dxd downstream wire end displacement - X
dyd downstream wire end displacement - Y

CDC/alignment

CDC_ALIGN_UPSTREAM_DZ upstream endplate z displacement
CDC_ALIGN_DOWNSTREAM_DZ downstream endplate z displacement
CDC_SAG_RADIUS

CDC/cdc_gas_tables, 41 rows

1-100 time-to-distance lookup tables

CDC/drift_parms

CDC_DRIFT_FUNCTION index for which row of CDC/cdc_gas_drift should be used

Note - maybe this should be a JANA parameter?

CDC/MC/drift\_func\_parms

CDC_DRIFT_A Transverse drift function parameters
CDC_DRIFT_B
CDC_DRIFT_C
CDC_DRIFT_D
CDC_DRIFT_A_L Longitudinal drift function parameters
CDC_DRIFT_B_L
CDC_DRIFT_C_L
CDC_DRIFT_D_L

CDC/fit\_parms

CDC_VARIANCE_A Kalman filter parameters
CDC_VARIANCE_B
CDC_VARIANCE_C

Deprecated

The following tables should not be used anymore:

  • CDC/cdc_drift - parameterized time-to-distance function
