◆ Medium() [2/2]

virtual void TVirtualMCGeometry::Medium ( Int_t kmed,
const char *  name,
Int_t  nmat,
Int_t  isvol,
Int_t  ifield,
Double_t  fieldm,
Double_t  tmaxfd,
Double_t  stemax,
Double_t  deemax,
Double_t  epsil,
Double_t  stmin,
Double_t ubuf,
Int_t  nbuf 
)
pure virtual

The same as previous but in double precision.

Implemented in TGeoMCGeometry.

◆ MediumId()

virtual Int_t TVirtualMCGeometry::MediumId ( const char *  mediumName) const
pure virtual

Return the unique numeric identifier for medium name mediumName.

Implemented in TGeoMCGeometry.

◆ Mixture() [1/2]

virtual void TVirtualMCGeometry::Mixture ( Int_t kmat,
const char *  name,
Float_t a,
Float_t z,
Double_t  dens,
Int_t  nlmat,
Float_t wmat 
)
pure virtual

Define mixture or compound with a number kmat composed by the basic nlmat materials defined by arrays a, z and wmat.

If nlmat > 0 then wmat contains the proportion by weights of each basic material in the mixture. If nlmat < 0 then wmat contains the number of atoms of a given kind into the molecule of the compound. In this case, wmat in output is changed to relative weights.

Implemented in TGeoMCGeometry.
