BTOF Simulations

 

Barrel TOF/CTB Geometry Configurations

The definitions of Barrel TOF/CTB geometry configurations are shown here:

BtofConfigure = 1;      /// All CTB trays

BtofConfigure = 2;      /// All TOFp trays

BtofConfigure = 3;      /// big TOFp path (trays from 46 to 60), rest are CTB trays

BtofConfigure = 4;      /// Run-2: one TOFp tray (id=92), rest CTB

BtofConfigure = 5;      /// Run-3: one TOFp (id=92) tray and one TOFr (id=83) tray, rest CTB

BtofConfigure = 6;     /// Full barrel MRPC-TOF

BtofConfigure = 7;      /// Run-4: one TOFp (id=93) tray and one TOFr (id=83) tray, rest CTB

BtofConfigure = 8;      /// Run-5: one TOFr5 (id=83) tray, rest CTB

BtofConfigure = 9;      /// Run-6: same as Run-5

BtofConfigure = 10;    /// Run-7: same as Run-5

BtofConfigure = 11;    /// Run-8: Five TOFr8 trays (id=76-80), rest CTB

BtofConfigure = 12;    /// Run-9: 94 installed trays, rest slots are empty

 

TOF selections in different geometry tags should be in the followints:

year 2002:     Itof=2;    BtofConfigure=4;

year 2003:     Itof=2;    BtofConfigure=5;

year 2004:     Itof=2;    BtofConfigure=7;

year 2005:     Itof=4;    BtofConfigure=8;

year 2006;     Itof=5;    BtofConfigure=9;

year 2007:     Itof=5;    BtofConfigure=10;

year 2008:     Itof=6;    BtofConfigure=11;

year 2009:     Itof=6;    BtofConfigure=12;

All geometry in UPGRxx should use BtofConfigure=6 (full TOF configuration).

TOF Simulation Resolution Database

 Variables:
    unsigned short resolution[23040]; // The BTOF time resolution for a given cell used in simulation.
    octet algoFlag[120]; // information about granularity of parameters 0-cell by cell, 1-module by module, 2-TDIG, 3-tray
 
Frequency:
This table will be updated whenever the Calibrations_tof::* tables are updated, generally once per RHIC Run
 
 
Index:
*table is not indexed
 
 
Size:
The size of one row is 2*23040 + 1*120 = 46200 bytes (also verified by compiling and checking).
