Instrumented Coil

The coil is treated as a cylinder of `sensitive' aluminium material in the routine COILMAT so that the amount of energy lost in the coil can be obtained. In addition a cylindrical layer of scintillator is included at the outside of the coil to act as a coil `calorimeter'. The output is included in the common COILHITS:

      INTEGER NCLMAX
      PARAMETER(NCLMAX=1000)
      REAL ECLMAT,ECLSCN,ECLMTOT,ECLSTOT
      INTEGER ICLTRAK,NUMBVCL,NCLMAT,NCLSCN
      COMMON /COILHITS/ECLMAT(4,NCLMAX),ECLSCN(4,NCLMAX),ICLTRAK(NCLMAX),
     &                 NUMBVCL(NCLMAX),NCLMAT,NCLSCN,ECLMTOT,ECLSTOT

where NCLHITS is the number of coil hits, ECLMAT(4,IHIT),ECLSCN(4,IHIT) are the energy deposits and ECLMAT(I,IHIT),ECLSCN(I,IHIT) I=1,3 are the x,y,z coordinates of the deposits in the MATerial and SCiNtillator respectively. ICLTRAK is the GEANT track which produced the hit. The total energies deposited in the coil material and scintillator are returned in the variables ECLMTOT,ECLSTOT respectively.
