TRiP98 dE/dx command
dEdx item / import() list energy() debug
export() delete projectile()
read display dx()
write inspect eps(0.002)
prefix() alias()
Purpose
Handles input and output and interpolation of energy loss (dE/dx) tables.
Parameters
- item
-
For the input options
(read and import())
specifies a list of files, optionally wildcarded or including
shell variables, to be read as
dE/dx tables.
Usually energy loss tables have the extension
".dedx"
For all other options: name of the material for which the dE/dx is
to be processed. A "*" means all types, a list of
types has to be put in double quotes.
- import()
-
Not yet implemented.
- export(fmt)
-
Exports a dE/dx table in some non-native format,
at present only <fmt>="gd" is implemented to export for the
gd plot program.
File name convention is:
<prefix><item>.dedx.gd
- read
-
Read a dE/dx table specified by item.
- write
-
Write the dE/dx table for material item
File name convention is:
<prefix><item>.dedx
- prefix()
-
Prefix for output (write,export()) file names.
- list
-
List the dE/dx table for material item
- delete
-
Delete the dE/dx table for material item
- display
-
Display the dE/dx table for material item.
Not yet implemented.
- inspect
-
Show some internal info about the dE/dx table for material item.
- energy(energy)
-
When specified together with projectile()
the dE/dx for the
specified beam energy (MeV/u) will be computed from the
dE/dx table for material item.
- projectile(proj)
-
When specified together with energy()
the dE/dx for the
specified projectile will be computed from the
dE/dx table for material item.
- dx(deltax)
-
A thickness (g/cm**2).
When specified together with projectile()
and energy() the amount of energy (MeV/u) lost
within
<deltax>
is computed.
- eps(eps)
-
Accuracy parameter effective together with deltax().
The specified thickness is subdivided into layers so that the energy loss
does not change more than
<eps>
.
- alias()
-
Define an alias name for a material.
- debug
-
Debug switch. Lots of output!
Remark
none
Examples
-
dedx $TRIP98/DATA/19990304.dedx /read
Reads the specified file in the directory "$TRIP98/DATA" and interpretes it as
a dE/dx table.
-
dedx H2O /proj(10B) energy(270) dx(1)
For the projectile 10B of 270 MeV/u the dE/dx in H2O as well
as the lost energy within 1 g/cm**2 is calculated.
-
dedx film / alias(H2O)
Defines a dummy energy loss table for material film
which points to a "real" table H2O
(which must exist).
